Hi,my name is Evgenia Kouzoudi!
I have installed gap under windows and I have a problem. I hope you can help
me.
I have written a program and after 1 hour the program stopped and gap
returned:
"cannot extend the workspace anymore". I have read the install.win and there
"If Things Go Wrong". I have read that I must write a command with -o... in
the command line. Is this line in gap.bat the command line?
"c:\windows\gap\gap4r1\bin\gapw95.exe -m 14m -l c:\windows\gap\gap4r1;%1 %2
%3 %4 %5 %6 %7 %8"
I tried to write -o 64m in this line but it deosn't work? Must I write this
command in another place or must make something other.
I hope you can help me. Thank you.

Sorry about my late response. The option '-o 64m' should
probably read '-m 64m', I think. For starting GAP 4.1 under Windows 95,
I use an adjusted version of the batch file distributed together with GAP 3
(see below). Up to now, I did not encounter any problems with this choice.

Maybe, your computer has got much less than 64 MB RAM, or your
program needs in fact more than 64 MB - if this is the case, you probably
will notice permanent harddisc activity due to accessing the swap space
when running your program.

By the way, my experience is that when GAP under Windows starts
permanent swapping, the desired results are usually not obtained during
an 'awaitable' amount of time in most cases, so I often just stop the
computation after some time in such a situation.

Hope this helps,

Stefan
