Part of this question was already answered in this posting: http://communities.sas.com/thread/33031?tstart=0

And this is a very good paper on how to approach writing a macro program: http://www2.sas.com/proceedings/sugi28/056-28.pdf

Also, it is not clear to me what you mean by this:

"1. select customername RAM and TRUE ." or

"2. selectcustomername HARI and TRUE"

This would indicate some kind of WHERE condition like:

proc print data=mydata;

  where customername="&selectcustomername" and ????????"; but where does the TRUE come from in the data that you show what is the variable or condition that must = "TRUE"????

Also, the 2 conditions in #2 and #4 are the same, but you show different results.
