How can a character value be less than a numeric value, among other things;
and macro variables don't use decimals in regular evaluations.  You should
really be using a data step to work that out anyway.

What are you trying to achieve?  Your code doesn't really make sense to me.
Are you trying to conditionally create a single dataset?  If so then just do
the conditional bit in your first step, if nothing else...
