When you're starting out with macro coding, always think about what
the code should be first, then work out how to macro-ize it.

Here, you need to use the global option MPRINT so that all your
macro code is printed out in the log and you can see how it looks.
If you do that, you'll see that you have IML code with a PROC
SURVEYSELECT stuck in the middle of it.  Obviously, that won't
work.  The best you can do is create the replicated data set, and
*then* run the IML code on that replicated file.


So.. why do you want to use IML, and why do you want to use
PROC SURVEYSELECT, and what is the goal of your efforts?  If
you explain what the 'big picture' is, someone may be able to
give you better advice.
