I'm trying to perform psm for my data and i find that there's no proc psmatch before version sas9.4 m4. I've done psm in my personal computer using sas9.4 m5 but I cant update sas in other people's computer cause it's confidential. So i try to used macro to perform greedy match refering to Parsons' paper, and i wonder if there was macro procedure for optimal match??

This is the first log, it looks weird: 4671 %put &p_nor &ProbF; 2.78E-16 0.5349 4672 %MACRO a; 4673 %if &p_nor>2.78 and &ProbF>0.1 %then %do; 4674 %put &p_nor>0.1 and &ProbF>0.1; 4675 %end; 4676 %else %do; 4677 %put else; 4678 %end; 4679 %MEND; 4680 %a 2.78E-16>0.1 and 0.5349>0.1 and then i try this one: 4685 %put &p_nor &ProbF; 2.78E-16 0.5349 4686 %MACRO a; 4687 %if &p_nor>2.79 and &ProbF>0.1 %then %do; 4688 %put &p_nor>2.79 and &ProbF>0.1; 4689 %end; 4690 %else %do; 4691 %put else; 4692 %end; 4693 %MEND; 4694 %a else when i assign a scientific notation to a macro variable,it seems sas make the judgement by using the numeric part of the macro variable. it shows that in sas macro 2.78E-16>0.1 and 2.78E-16<2.79. how to make sas to make a right judgement???
