I use a very old program which happily uses all available extended/expanded memory. For example, in my Windows XP machine I have 2 Gb of RAM and the program can use 500 Mb if I ask it to, no problem.

But setting memsize=63 in DOSBox only provides about 63 Mb of available memory for workspace. Is there any way to increase the memory DOSBox will allocate to the program?

The program I refer to is APL*Plus II/386 which isn't a "game" per se, but it is so wonderful that it's as good as a game as far as I'm concerned.

Please help!

Thank you.

change sourcecode, recompile and hope it works. No plans on supporting it.

Bruce,

Did you manage to find a way to allocate more memory to APL*PLUS/386?

Have a look at DOSBox-X, it does support larger memory sizes, and supports non-game applications.

1dosbox-x -set memsize=512
