Quoting Daniel Nordlund <djnordlund@VERIZON.NET>:

If you are interested, I can send you a copy of my macro _contrgen.
It generates contrast statements for GLM, MIXED and GENMOD.  I make
extensive use of the macro features of IML, and could not do the
things that I do in that macro without IML.  Things like running a
macro do-loop with bounds set in the statement immediately before it,
and other stuff that just looks odd if you are used to standard SAS
macro stuff.
