HELP NEWS.9
For most recent news, see HELP NEWS

Dec 13 1984
    The procedure *NEWANYARRAY has been changed so that arrays can be made
    that share elements with other arrays.

Dec 11
    * The procedure ved_print has been modified to take another argument, so
    can now be used with different printers.  Error messages tidied.
    See TEACH PRINTING.

Dec 7 - Version 10
    * External procedures can now be dynamically linked into both UNIX and VMS
    POPLOG systems, using the procedure EXTERNAL_LOAD. See REF EXTERNAL.

    * $poplocalauto has been moved to the front of POPLIBLIST (it should have
    always have been there). This means that a definition in the local library
    will override one in the main library. Similarily, the local "lib"
    directory now appears before the main one in POPUSESLIST.

    * The VM code-planting procedures (sysPUSH, sysPOP, etc) are now procedure
    variables. This means that with LIB SHOWCODE loaded (and POP_SHOW_CODE set
    true), 'tracing' output will be produced for POP-11 compilation.

Nov 28 1984
    POPLOG now dies on receipt of a hangup signal (e.g. when terminal exchange
    times out) instead of getting into a state in which it just consumes
    resources. Later it will be modified to die more gracefully,
    saving files in the VED buffer.

Oct 24
    Library procedure *FULL_IDENTPROPS added.  HELP *IDENTIFIERS added to
    clarify the different attributes.  Now it's possible to get at all
    information for an identifier.

Oct 20
    Library files to do with interactive mode and interactive cshell in ved
    (im.p, ved_im.p, imcsh.p, ved_imcsh.p etc) moved into main library.

Oct 19
    The macro #_< ... >_# allows evaluation of expressions at compile-time.
    See HELP * HASH_< .

Oct 15
    Added HELP CRSV and modified HELP SYSSAVE to refer to REF SYSUTIL

Oct 4 1984 -- Version 9.3
    * Compilation inside VED has been tidied up and generally rationalised.
    Specifically this means:
        1. The commands ENTER l, l1, c, c1, x and x1 now all use the load
           marked range mechanism, e.g. running ENTER l1 on a file is
           equivalent to marking the whole file as a range and doing ENTER
           lmr. This means that output produced (and terminal input requested)
           by the compiled program will go to whereever lmr would put it.
               The c, c1, x and x1 commands now also have a facility for
           returning after compilation to a given ved file, rather than to the
           compiler outside ved. if the variable VED_POP_BACK_FILE is a
           string, then return will be to the file of that name; if otherwise
           TRUE, return will be to the current file at the time of doing the
           command. FALSE (the default) means leave ved and go to the outside
           compiler.

        2. The load mark range facility now makes provision for programs which
           attempt to read from the terminal (i.e. from charin). If this
           happens, the compilation process is suspended and input is
           requested from whatever file is specified for output by
           VEDLMR_PRINT_IN_FILE. When input is requested from a file, the
           current prompt is inserted in the file, and the character "I"
           appears on the status line, indicating that there is a process
           waiting for input. Input can then be typed into the file, and given
           to the waiting process either by (a) lmr'ing the input as a
           marked range or (b) if the variable VEDCRINTERACTIVE is true by
           simply typing RETURN on any line.
               Note that this applies to input from CHARIN, and NOT from the
           current proglist when compiling, e.g. as currently, compiling
                            READITEM()=>
           will return <termin> because the marked range is exhausted. (To
           surmount this problem READLINE is redefined so that when VEDEDITING
           is true, it reads from a new proglist set up from CHARIN -- this
           means that VEDREADLINE is now redundant).

        3. An 'ongoing' compilation process can be set up in any ved file by
           calling the procedure VEDSETPOP inside that file. The compilation
           process reads input from, and produces output in the file, so that
           the interaction will appear like normal 'terminal' mode. Otherwise
           VEDSETPOP behaves like SETPOP, in that it calls POPSETPOP before
           calling COMPILE(CHARIN). Calling SETPOP inside VEDSETPOP resets
           only back to VEDSETPOP and not right up to the top-level.

    * POPPROMPT can now be a procedure, to allow for 'intelligent' prompts;
    see *POPPROMPT.

Sep 27
    The environment variable "popsavelib" names the directory where system
    saved images reside (i.e. currently pop/lib).
Sep 12
    TEACH PRIMER is a long, incomplete, introduction to POP-11 for
    people who already have programming experience. It replaces
    TEACH PRIMER.*, TEACH POPNOTES, TEACH POPSUMMARY, TEACH LISTSUMMARY.
    TEACH TEACHFILES updated

    HELP CONTENTS has been slightly extended.

    HELP POPLOG gives information about versions of Poplog for other
        machines and operating systems.

    VED ENTER H, and the macro HH have been withdrawn, owing to
    unsatisfactory performance. Apologies.
Sep 10
    VEDCHARINSERT altered so that when VEDBREAK is TRUE, and current
    line is too long, it looks for a space to the right, or to the left
    at which to break the line. It used to break at cursor location.
Sep 4
    VEDSETKEY altered to accept a word as second argument. E.g. its value
    may be a procedure or character table.
Sep 3 1984
    Entry for VED_SW put in HELP * VEDCOMMS
Aug 30
    HELP * EFFICIENCY provides hints on writing more efficient POP-11
    programs
Aug 21
    A bug deep in the VT100 version of VED, which caused wrong screen
    addressing to be used for column numbers > 99 has been fixed.
    This bug interfered with VED ENTER LL.
Aug 17th
    LIB TVI925 provided by Jim Hunter (unsupported) for Televideo 925
    VDU. For details: SHOWLIB TVI925

    New version of LIB V55 for Visual 55 VDU. See HELP * V55
August 17
    VEDSTATUSLINE now made accessible to users
August 10
    HELP VEDWYSE describes LIB VEDWYSE for use of VED with WYSE VDU
    The stack of marked ranges manipulated by vedmarkpush and vedmarkpop is
    now local to each file. ENTER LCP has been altered to use this stack in an
    attempt to stop the appearance of spurious marked ranges under certain
    circumstances.

    VEDLINEDELETE now checks that current line is before the end of the
    current file before doing anything.

    On switching to another window, the current line is only indicated as
    being marked if the current value of vedscreenmark is not `\s`.
August 6
    Prolog predicates now keep their local values in stack variables: speed
    improvement is around 20 percent.
    Spy no longer dereferences arguments to predicates -- this could make
    predicates written in POP11 easier to debug.
August 3 1984
    The LISP saved image is no longer constructed in such a way that
    it loads vedinit.p independently of whether you run VED. Loading
    is delayed until you first run VED.
July 25
    ENTER LL
    To convert VT100 to long line mode, used not to work. A temporary
    fix has been provided which will deal with most simple cases of use.
    It assumes the VT100 can only handle 14 lines in 132 column mode.
    For details SHOWLIB VED_LL. For more advanced terminals, alter
    14 to 24, or whatever.

July 23
    LIB SLOWPROCS extended to enable checking procedures to be switched in
    and out, by addition of procedure slowprocs.  See SHOWLIB SLOWPROCS.

July 16
    LIB KEYPAD
      This may be of use for VDUS without 'alternate keypad' mode.
      For details SHOWLIB KEYPAD

    LIB VEDIOCONTROL
    This command makes more control characters accessible to
    VED instead of being trapped by UNIX. See HELP * VEDIOCONTROL
July 12 1984
    * ENTER h fixed to work on unix 4.2 (see HELP HELP for info about h)

June 9
    * "strnumber" now uses the itemiser to produce a number from a string.
    This means it will cope with any valid number representation allowed by
    the latter, e.g. radixes etc. It will also allow a number with leading or
    trailing spaces.

    * "systranslate" now does NOT attempt to produce a number from the
    translation of the given environment variable (i.e. using strnumber on
    it). It was a mistake that it ever did (and the fact that it did was
    never advertised in the documentation). If you want a number, use
    strnumber to get it.

June 4
    * (Unix Only) "sysdaytime" now produces a date string without forking a
    shell to run Unix "date". It does this by using two new procedures:
    "sys_real_time" returns the time as a number of seconds since midnight
    1 Jan 1970, and "sys_convert_date" which takes such a number and produces
    the date string from it. (The VMS system will also possess these
    procedures in the near future...). See REF SYSUTIL.

    * The quotient and remainder operation "//" can now take integer-valued
    ddecimal arguments (single-length decimals are not allowed, since the
    point is to allow the representation of large integers as ddecimals, and
    decimals can't represent these.)

June 2
    LISPNEWS updated
June 1 1984 -- Version 9.1
    (1) Changes to printing in the system:

        * Problems with redefining the "class_print" procedure for a data type
    and then calling "syspr" inside that procedure have now been fixed. syspr
    is now defined simply as

                define syspr(x); class_print(datakey(x))(x) enddefine;

    and the actual task of doing printing has been moved to the new procedure
    "sys_syspr", which will print any object in the system (including user
    records and vectors), and is the default class_print for all objects.
    if you do

                syspr -> class_print(key)

    class_print will assume you meant sys_syspr and not syspr, otherwise
    infinite recursion would occur ...

        * Two new variables which control printing have been introduced. The
    first, "pop_pr_exponent", will cause decimals/ddecimals to print in
    exponent format if set true. E.g.

                1234567890.0   prints as   1.23456789e+9
                0.1234567890   prints as   1.23456789e-1

    The second is "pop_pr_quotes", which if true causes strings to be printed
    inside string quotes. Note that this is now set true locally by
    "sysprmishap" when printing the INVOLVING list, so that strings are
    distinguishable from words.

        * In the interests of consistency the variable "popdplaces" which
    controls the number of fractional places to which decimals are printed
    (including in exponent format), is now renamed "pop_pr_places"
    ("popdplaces" remains as an autoloadable synonym, however). There are thus
    4 "pop_pr_" variables controlling sys_syspr:

                pop_pr_radix
                pop_pr_places
                pop_pr_exponent
                pop_pr_quotes

    (2) (VMS only) SYS_FILE_MATCH now returns all file names in lower case,
    for compatibility with the rest of the system.

    (2) (VMS only) Problems with restoring saved images after the DCL command
    SET COMMAND has been used are now cured.
May 29
    LIB FINDLINES fixed to work with VTURTLE
May 24
    LIB VEDKEY5 altered so that you can create blank space below the cursor
    when at the end of file.

May 3 1984
    The * EXPLAIN library macro has been fixed to work for UNIX.
    It prints out help files, using the unix 'more' facility.
    This enables people without suitable VDUs for VED to access help files.

    LIB WINDOWS had stopped working owing to changes in the heart of VED.
    It has been patched temporarily. See HELP WINDOWS for details. Nothing
    is guaranteed.
April 24
    * The procedure "sys_io_control" now makes available the functionality of
    the UNIX "ioctl" system call. It can also be used to change the
    characteristics of a terminal device like popdevraw so that shell control
    characters can be enabled or disabled inside ved, etc. See sys_io_control
    in REF SYSIO.

    * $, % and ! at the start of an ordinary terminal line and ENTER $,
    ENTER % and ENTER ! from ved now call /bin/sh, /bin/csh and
    systranslate('SHELL') respectively.

    * The library procedure "random" has been improved.

April 19
    Bug in lib actor fixed (procedure GPO now works)
April 16
    Bug in vedchardelete involving tabs has been fixed. It also affected
    VED substitutions with search strings crossing line boundaries.
April 9
    The changes made to the ved terminal interface have now been removed, i.e.
    all shell control characters (^S, ^Q, etc) have been restored. Instead, a
    new facility will be introduced to enable the terminal characteristics of
    popdevraw and other terminal devices to be user-assignable.
April 6th 1984
    Bug in CATCH and THROW fixed. THROW previously caused an infinite
    loop in certain circumstances.
Mar 27
    New VED_FILL speeded up and incorporated into the system, library version
    withdrawn. VED_J uses VEDCOMPILEABLE to choose between VED_TIDY and
    VED_FILL.

    ENTER NAME no longer allows the current file to be given the same name as
    a file currently being edited.

    VEDPRESENT(string) provided for checking whether a file named <string> is
    being edited. Returns the file structure, or FALSE.
Mar 22
    Changes in 'raw' mode(used by VED): All Unix signals except intr and quit
    are disabled, enabling the character to be used for VED commands.
    Also XTABS mode is turned off i.e. tab characters sent to the terminal via
    rawcharout will not be converted to spaces.
Mar 16
    VED_FILL altered to do less unnecessary alteration of screen.
    VED_JJ and VED_JJP altered to use it. See HELP PAGE
Mar 15
    Bug in ENTER LS fixed. Large values of poppid used to fool it.
    SYSLIBCOMPILE now takes an optional second argument, a list, specifying
    the directories to be searched for the file, default is POPLIBLIST.
    This has been used to fix a bug in LOADLIB and thus LIB.

    LIB PAGE has been extended.
    LIB RNO provides some runoff-style commands for use with LIB PAGE.
    For details see HELP * PAGE.

Mar 13 1984 -- Version 9.0

    * 'Layered' saved images: These are based on the new procedure
    "sys_lock_system", which allows a saved image to be created in which
    data structures are paritioned into constant and non-constant areas. See
    REF SYSUTIL.

    * LVARS: These are a new kind of variable which are intended (in the long
    run) to be lexically as opposed to dynamically scoped. At the moment full
    lexical scoping is not supported, and lvars must always be local to any
    procedure in which they are used, i.e. a non-local reference like

            define foo();
                lvars x;
                define baz(); x => enddefine
            enddefine;

    is not allowed. In their present form, their main advantage is efficiency,
    since they are allocated either to registers or to cells in the procedure
    stack frame (giving faster access and compacter code).
        "lvars" are declared just like "vars", and for the duration of the
    procedure in which they are declared will override any dynamic declaration
    for the same name. Since a procedure can now have two kinds of variable,
    formal argument and result variables are now ambiguous (i.e. are they
    "vars" or "lvars" ?). They will default to "vars", but the POP compiler
    has been changed so that this default declaration will be made ONLY for
    names which do not appear in any "vars" or "lvars" statements immediately
    following the procedure header. This allows formals to be declared in such
    statements, and it is recommended that you now declare all formals in this
    way, e.g.

            define foo(x, y, z) -> p;
                vars z u v w;
                lvars x a y b c d procedure p;
                ...
            enddefine;

    etc. Note also that since the first TWO lvars are allocated to registers,
    this allows any chosen variables to get the registers (i.e. x and a in
    the example above.
        New associated virtual machine facilities are sysLVARS and
    sysNEW_LVAR -- see REF SYSCOMPILE.

    * log10(x) added to the library. Computes log of x to base 10.


Feb 28
    TEACH TRANSSENT improved. DOC PRIMER removed from exported files.
    (See TEACH PRIMER.CON)
Feb 16
    TEACH READLINE improved
Feb 14
    HELP ACTIVE added.
Feb 13
    ENTER F has been told about procedure header syntax, so it can now find
    macros, operations etc... The new flag '-x' makes the search exact i.e.
    ENTER F -x foobaz, will succed only if the procedure foobaz is defined in
    the current file, otherwise foobaz3 and foobazgrum will also be found.
    (ENTER FF is now a synonym for ENTER F).
Feb 8
    Bug in updater of fast_subscrs fixed
 Feb 1 1984
    ENTER send - now writes (and deletes) the message file in the user's home
    directory.
Jan 27
    LIB v500 for Visual 500 brought up to date.
    ENTER pwd - displays current directory.
    ENTER cd - changes current directory. See * CD.
        Causes MISHAP if target directory doesn't exist.
    ENTER date - displays the system's current time and date.
Jan 16
    Bug in LIB FINGER fixed - (See TEACH FINGER)
    Prolog version 8.2.1.
    Several alterations to the core of Prolog to improve performance
    and remove various bugs. However there are many more alterations
    needed.... Itemising and therefore compiling should be faster, as
    well as running.
Jan 4 1984
    SYSFILENAME altered for UNIX. Returns everything after the last "/".
    VEDFILESELECT provided for moving between files. See help file.
Dec 29
    LIB PROLOGLIBLIST extends POPUSESLIST to include PROLOG library
    directories. See HELP * PROLOGLIBLIST.
    ISDYNAMIC can be used to check if something is a dynamic list.
Dec 28
    ISINCHARITEM can be applied to a procedure to see if it was produced
     by INCHARITEM. If applied to ITEMREAD or READITEM it checks to see
     whether PROGLIST is generated by a procedure produced by INCHARITEM.
     ISINCHARITEM returns FALSE or the generating procedure.

    PROLOG itemising has been considerably speeded up. It is now about
        3.5 times as fast. Compiling is therefore about 12% faster.
Dec 27
    VED ENTER grep string file-names
        runs grep with the given arguments, and reads the output into
        a temporary VED file.   HELP * VEDCOMMS updated
    HELP * CONTENTS updated. New section for UNIX added.
    HELP * UNIX points to files with information about accessing UNIX
        from POP
    HELP * POPENVLIST gives information about UNIX environment variables
    HELP * SYSEXECUTE gives information about invoking Unix facilities.
    HELP * SYSOBEY brought up to date for UNIX
    SYSOBEYLIST made to use the value of environment variable SHELL
    SHELLOBEY(string) is like sysobey but uses value of current
        environment variable 'SHELL'.

    ENTER ls - replaces ENTER dir for UNIX POPLOG. See HELP * VEDCOMMS
        ENTER LS uses CSHELL to analyse file names. So '~' works.
    ENTER del improved
    ENTER purge altered to use ENTER ls
    ENTER lsx   behaves like ls -x i.e. file names in columns across page
    HELP * VEDCOMMS updated
    * SYSFILEDIR and * SYSFILETYPE altered to suit unix.
    Removed library and help file for WHEREIS - local to sussex
Dec 23
    If commands like help, teach, showlib, etc are invoked outside VED
    and they don't find the relevant file, then after printing the message
    they call interrupt.

Dec 22
    FNCOMP added as a synononym for PDCOMP, for compatibility with POP2
        note: <> can be used to concatenate procedures.
Dec 9th
    LIB VCALC now does more checking for consistency
Dec 8th 1983
    LIB MSBLOCKS installed. See TEACH MSBLOCKS - introduces a
        SHRDLU-like program using the editor as display.
Nov 29th
    LIB RECORD altered so that RECORD and ENDRECORD can be used in
        procedures. I.e. the macros plant code instead of running it.
Nov 26
    Bug causing uninterruptable loop occasionally after 'recursion level
    exceeded' has been cured.
Nov 25
    There is a new mechanism for defining SHELL commands to run pop11.
    See * HELP INITIAL.
    Various help files have been updated for Unix
    INITIAL, PARAMETERS, SYSSAVE
Nov 17
    HELP * SMATCH describes LIB SMATCH, for using the matcher in a section.
    ENTER SHELL runs the shell commands in current ved file
    ENTER PURGE now works.
    Bug in TURTLE_PR fixed - now autoloads DRAW properly
Nov 11
    LIB HALTS now works as described in HELP * HALTS
Nov 4
    vedmidwindow    sets currentline at middle of window

    LIB V55     converts VED for visual 55. SHOWLIB V55. See HELP * V55

    LIB FORMS   (experimental) provides a powerful new utility for
            extending the syntax of POP-11. See HELP * FORMS
    LIB V500 should have been called LIB V550 and has been renamed.
    Similarly HELP V500. Sorry.

Nov 1 1983
    * A bug which caused vedputmessage sometimes to display messages in
    the wrong part of the screen has been fixed.

    * The file vedopen.p has been removed from the library as the
    procedure vedopen is now defined in the system.

Oct 30 - Version 8.2
    * Some internal changes have been made to the Prolog system procedures to
    speed up matching of arguments to Prolog clauses.

    * TRACE now attempts to autoload its arguments.

Oct 27
    The variable * pop_file_mode, which determines the default protection
    for files created by * syscreate and derivatives, is now 8:664.
    I.e. files are readable and writeable by the same group.
Oct 26
    * In the interests of making them more readable and less verbose, the
    'fast_integer_' operators have been renamed. The 'fast_integer_' prefix
    has been condensed to 'fi_', and the remainder of the name has been
    replaced by its sign character equivalent. The operators now available are
    therefore:
        fi_+  fi_-  fi_*  fi_//
        fi_<  fi_<=  fi_>  fi_>=
    The old names remain as autoloadable library procedures.

    * An itemiser bug which prevented a character that had redefined as a
    string quote being recognised as such has now been fixed.

Oct 20 1983
    HELP SHELL, HELP PRINTING and HELP MAIL are now available on UNIX.

    The REF POPINDEX and REF VEDINDEX files have been updated for UNIX.
    ENTER SOURCEFILE now available for UNIX.

    VEDGETLIBFILENAME has been altered so that it ignores elements
    of the directory list which are procedurs rather than names. Thus
    SHOWLIB now works in situations in which it used sometimes to
    produce an error.

Oct 14 1983
    ENTER helpkey
    Then press the key. It will find the relevant entry in HELP VEDCOMMS
    or HELP VEDPROCS and put it on the screen.

    LIB V500 provides a version of VED for the VISUAL 500 terminal. See
    HELP V500
COMING SOON

    ----------------------
Oct 13 1983
    The RECORD command for recording interactions with POP-11 has been
    extended.
        (a) record and endrecord are now macros not operations.
            so they cannot be used inside procedures.
        (b) record allows an optional filename to be specified,
            see HELP * RECORD for details
        (c) if a previous file of the same name exists, then instead
            of being lost as before, it is copied into the new file. I.e.
            the new interaction record is appended to the old file.

October 10 1983
    ENTER NDIR has been patched and now works on UNIX.

September 30 1983
    * There is now a syntax for putting arbitrary character values 0 - 255
    into a quoted string (or after an alphabeticiser character, etc).
    This is the character value preceded by "\(" and followed by ")", e.g.
        '\(97)A\(255)'
    is a string of 3 characters, 97, 65 and 255. The integer between the
    parentheses can use the full itemiser syntax for integers, and so can be
    preceded by a radix, etc.

    * termin now prints as <termin>, rather than as ^D. This makes it
    machine/operating system independent.

Setptember 29 1983 - Version 8.1
    * What happens when any non-procedure object is applied as if it were a
    procedure can now be controlled by altering the CLASS_APPLY procedure for
    the data type. If X is any object, and P is CLASS_APPLY(DATAKEY(X)), then
    attempting to apply X as a procedure will result in P being called with X
    as argument, i.e. P(X). Similarily, an updater call of X will turn into
    a call of the updater of P, i.e -> P(X).
        In addition, the updaters of CLASS_APPLY, CLASS_PRINT and CLASS_=
    can now be used to change the corresponding procedure for ANY key,
    including all built-in data types (even integers and decimals). Thus you
    can for example change how integers are printed, or what happens when one
    is applied as a procedure.
        See REF KEYS for full details.

    * An empty expression following the assignment arrows -> and ->> will
    now be interpreted as meaning "erase an item from the stack". E.g.
            ERASE(FOO());
    can now be written more elegantly as
            FOO() ->;
    Another example: if BAZ is 3-result procedure and the second result is not
    required then
            BAZ() -> X, ERASE(), -> Y;
    can be written instead as
            BAZ() -> X -> -> Y;

September 28 1983
    Prolog local directories have been moved to
        [pop.local.plog...]
    This makes tape dumping easier.
September 27 1983
    While the printer in Arts E is broken, you can print things out in
    the computer centre, behind MAPS 2.  To make this easier, you can now use
        ENTER CCPRINT
    from VED.  This works just like ENTER PRINT, (See *PRINTING) but it comes
    out in the computing centre.  Or, from DCL, you can use
        $ CCPRINT filename
    this works just like $APRINT, but comes out somewhere else.

Sept 24 1983
    TRYSETVALOF(word,string1,string2) - for details see HELP * TRYSETVALOF
    Various VED enter commands have been re-defined to use this.

    VED ENTER set <variable>
    Uses TRYSETVALOF to switch the value of the variable.

    LIB VCALC is an experimental spreadsheet program. See help vcalc.

September 16 1983
    New LIB FACETS moved into system library - see HELP *FACETCHANGES.

Setember 5 1983
    Prolog Version 8.1
        Various bugs fixed.  Please see * PLOGNEWS

    ENTER MO - now complains BEFORE deleting range

Sept 2
    LIB SHOWTREE modified to use NEWVEDFILEPROP. New user-assignable
    procedures SHOWTREEINIT and SHOWTREEDEFAULTS added.

Sept 1 1983
    The external procedure mechanism has now been improved, to allow
    such procedures that require allocation of dynamic memory at run-time
    to function correctly. This means it is now possible to incorporate
    C/PASCAL/FORTRAN routines etc that do I/O. See REF EXTERNAL for full
    details.

    The itemiser now copes with all 8-bit characters from a character
    repeater, i.e. characters 0-255 (previously it only accepted 0-127).

    ENTER MI (Move Items) has been withdrawn due to a clash with
        ENTER MI (Move marked range Into current file).

Aug 30
    New procedures * NEWVEDFILEPROP and ISVEDFILEPROP to make it
    easier to associate extra properties with the current VED file.

    The online documentation commands DOC, REF, TEACH and HELP
    are changed so that they FIRST look in the corresponding
    LOCAL library. Also the default names will not be full path
    names, just individual file names.
    This is to simplify things for sites which wish
    to override Sussex defaults.

Aug 22
    Bug in VEDNEXTITEM removed: VVEDLINESIZE wasn't reset properly.

    UPPERTOLOWER and LOWERTOUPPER now return their argument if it isn't
    an alphabetic character.
Aug 18
    ENTER UL - underlining in VED. See SHOWLIB VED_UL
Aug 2
    The facility for following POP11 macros and VED ENTER commands for
    examining/editing files with a search string has been withdrawn. This
    is because it was incompatible with UNIX file pathnames containing "/"s,
    and caused such a filename in VAX/UNIX POPLOG to be interpreted as a
    search string...

    LIB FORMAT procedures are now individually autoloadable. They have also
        been sectioned off and (in some instances) speeded up. LIB FORMAT
        still loads all these procedures, as before.
Aug 1 1983
    sysfileextension - new auto-loadable procedure: like sysfiletype, but
        includes a '.' as part of the string returned.
