I think perhaps I had better qualify my remarks about "fragility" of POPLOG.
My working habits are such that I expect a the system to stay up for days so
that I can have icons on my desktop which remind me what I was doing.
(Contrast this with developing a C program in which the lifetime of a program
under development may be seconds).
POPLOG on the DECSTATION, which I have used in my office at UMASS, certainly
has this property now that DEC have sorted out problems with Ultrix. On the
Suns, somewhat to my surprise, I find that there is a fragility. Given that
Poplog is common to both situations, but the windowing systems are different,
it is clear that bugs in the SUN software is to blame. I am glad to
hear that better engineered software will be available for those popular
machines (DECSTATIONS in my experience do not deliver very good performance
for interactive working, however fast they may go on a single application).
My other question (b) was of course simply a question about how you overide
the default behaviour on quitting a window, which default reflects a mind-set
on the part of a manufacturer about the nature of programs which doesn't match
what you actually do with POPLOG (or for that matter many other systems).
Robin.
