HELP VEDREADLINE                             Aaron Sloman 11 Feb 1982

    vedreadline() -> line;

NOTE: This library no longer needed.  It has been preserved in case anyone
    was relying upon its stange behaviour.

VEDREADLINE is a procedure for reading a line of input which can be called
inside VED, e.g. using LMR (or CTRL-D with a marked range).  Ordinary
-readline- should now work better.  It starts a new line with the query
prompt '?'. You can then type anything you like on the line, editing as
normal, except that it won't let you move off the line If the line gets
too long, it scrolls left or right as needed. If you type RETURN or ENTER,
or CTRL-D it assumes you have finished, and all the text between the
brackets is made into a list, which is the result of VEDREADLINE. Is the
restriction to one line (of arbitrary length) acceptable?

You can try it out by a command like:

    repeat 5 times vedreadline()=> endrepeat;

Then mark the range and type CTRL-D

If you have two procedure calls on the same line which make use of
readline, make sure there's a space between them. E.g.

    vedreadline()=> vedreadline()=>

However, this format is not recommended for testing interactive programs.
Put each command on a separate line.
