Emulating EG concurrent processing feature in batch SAS

Hi,

We don't have EG in our environment and one of the features I've always liked in it is the ability to specify multiple concurrent processing streams that can get combined later when something like a merge takes place.

I've been thinking about how to create that with semaphores (probably 1 byte files) to kick off a similar environment using call system() or something similar.

Has anyone done this already? Would love to hear how you did it.

Thanks!

On UNIX, you do this in a shell script:

sas prog1.sas&
sas prog2.sas&
sas prog3.sas&
wait

The three SAS programs will be executed in parallel, and the script will terminate when all three SAS programs have finished.

Call this script from the main SAS program in a manner that makes SAS what for its termination.

Yeah, Unix variants have much nicer toys than Windows. This is on a Windows server, unfortunately.
