Casey,
This may or may not provide all the answers you are looking for, but for
whatever it is worth:
(1) Check out TS-628 - http://support.sas.com/techsup/technote/ts628.pdf
(2) OnlineDoc - Reeview the "What is New.." sections.

This would be a nice feature to have but it is not yet implemented. You may
be referring to the WARNING message that is issued when the length of the
BY variable from the second data set exceeds that of the first in a MERGE.
Note that when the order of the data sets is reversed even this WARNING
disappears. See below SIG.
Good luck.
