Chris has already pointed out how to use 9!:20 and that its default setting is unlikely to be your problem.

How large are the files?

The Windows host has a limit of about 2GB of address space for an application. In practice the max file size you could map would be less than 1BG given that you had enough hard disk space allocated for virtual memory use.

If you are on windows then there is an OS limit on the amount of virtual memory an application. You may want to check this in Setttngs|Control Panel|Advanced|Performance Settings (virtual memory).

Subject: [Jprogramming] how to increase memory


Hi!

I try to process large data files and while doing that I get 'out of memory' error message. I understand that I have to increase the memory limit by
setting 9!:20 or 9!:21, but I don't know how to do that.

The attempts to execute 9!:20 y or 9!:21 y, where y is some desired number bigger that default 2^30 will give me rank error. I also do not find any
examples of how to do that.

How should I do that or where could I read about it?

Thank you!
Kairit
