If it was in 6.07 then I should find the announcement in my treasured copy
of P-222.  Now that was a valuable set of updates, and I recall that when I
read whichever C & E document that announced it I was moved to experiment
and it became a favoured technique until it broke because of OS issues.

I don't recall it being in 5.18, and if it was, then it wasn't utilised
where I was using SAS at the time.  Since we migrated from 5.18 to 6.07 we
wouldn't have seen it in any intermediate releases.

Kind regards

David

According to a paper I wrote back in 1996, it was available in 6.07.
Phil Mason mentioned it in a SAStip in 1995.  The earliest mention in
the Google archive of comp.soft-sys.sas is of a presentation by Ian
Whitlock; it doesn't mention the release.

I'm fairly sure that CALL EXECUTE appeared and then disappeared, but I
don't remember the timing; perhaps it was in 5.18, not in 6.02, and
reappeared in 6.07?  It was a rare, but major, break in SAS Institute's
policy of backwards-compatibility.
