Determining the amount of system memory

[davidgraham]

In my application, I load a lot of information into a large array, when the array is full I write further information to file.

With different PC's I sould be able to make the array bigger and so my application should run faster.

I therefore need to determine the amount of system memory so I can decide how big I can make my array.

Is there a call that will give me this?

Thanks,
David

Here's how I find available physical memory with CVF 6.6:

use dfwin
use dflogm
use dfcom
(not sure which one of these is required)
...
type(T_MEMORYSTATUS) lpMstMemStat
...
call GlobalMemoryStatus ( lpMstMemStat )
ipmem_start = lpMstMemStat.dwAvailPhys
The last integer variable (ipmem_start) will have the amount of memory in bytes.

Note that physical memory is not the same as virtual memory. The dwTotalVirtual and dwAvailVirtiual fields are more interesting here.
