[GAP Forum] Changing memory allocation for GAP

Hello.

Is there a command for starting GAP from the command line to
open with a higher memory allocation, like 256 MB, than the standard 
one?

I use GAP v.4.4.12 on Mac OS Leopard.  At present, when I start GAP
I see the following:

--------

Loading the library. Please be patient, this may take a while.

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
Error, file "512m" must exist and be readable

I run search algorithms on groups of exponential complexity, and they
are intrinsically slow.  But I'm hoping that by using a higher initial
memory allocation, for practical purposes, my programs will cover
more of the search space than they have so far.

Sincerely, Sandeep.
