[GAP Forum] Changing memory allocation for GAP

[Asst. Prof. Dmitrii (Dima) Pasechnik]

Dear Sandeep,
it looks as if you start GAP in a wrong way.
(cause these > Error, file "-L" must exist and be readable
> Error, file "-m" must exist and be readable
> Error, file "128m" must exist and be readable
> Error, file "-o" must exist and be readable

things are mangled details of command line arguments...)

One way that works is to start it in a Terminal window.
Another is to use a special MacOSX application.

Hope this helps,
Dmitrii
