Harry, Peter and the other guys:
The reasons I want to use macros are:
1. I am trying to learn SAS macro processing.
2. I would like to carry out several different processes on
some of the variables in each obs, finding for the number of
odd number is just one of them, hence I think having these
processes package as a macro would be nice and modular.
3. I have already code and test several of these processes
as small macros that I have place in the autocall directory.
4. In general I want know the limits of SAS macro processing.
Thanks to all of you for your help.
