In proc SQL, I do get a note saying that:
NOTE: The "<>" operator is interpreted as "not equals".
In general, i find that we have different sas expressions, mostly identical
one another. Still, there remain definite differences among all of these
(1) data step expressions
(2) where statement expressions
(3) sql-expressions used in proc sql
(4) macro expressions
this is a less than ideal situation :-) but this may be an inevitable
consequence of sas' being around for a long time.
