XMRLMEM option

Obtain the amount of computer memory available to SAS with the undocumented XMRLMEM option.

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

The code shown above gives the total number of bytes of real memory available. (It does not count the operating system's virtual memory; only real memory). Divide this number by 1024 to get it into K's... or whatever to get it into Megs or Gigs.

XMRLMEM is an undocumented diagnostic option that can come in handy when considering allocating a bushel-full of buffers or considering doing some big-time hashing.

Formdlim option

FORMDLIM='delimiting-character'
