SAS memory – How much is there?

Here is a great one we snagged from the SAS community. The SAS option XMRLmem will give you the amount of physical memory available to your session.

Keep in mind that this is physical member not virtual (which also might be available).

You must also know to use the getoption function. This is an scl function to be used within a datastep. Here is an example from the guys at SAS community.

data _null_;
format amt comma20.;
amt = input(getoption('xmrlmem'),20.);
put amt=;
run;
