Absolutely agree.  PROC COMPARE is one of my favorites.  But the support for ODS tables is a joke.  Might as well go old school and PROC PRINTTO to a .lst file and read that in.

Yes, PROC COMPARE is an essential part of my testing processes. It is one of SAS's hidden gems as I suspect it is not that widely used.

Actually the standard COMPARE reporting could do with some sprucing up as well.

Bruce Gilsen gave a nice talk at SESUG 2017 on using PROC COMPARE to find matching variables.

Looking at his code was a reminder of how bad (IMHO) the PROC COMPARE ODS output datasets are.  It was as if we were in the pre-ODS days, where you used PROC PRINTTO to send .lst output to a file, and then parsed the file. 

 

Below is a printout of @Reeza's WANT dataset.  To me, this isn't really a dataset, it's just text output that was crammed into a character variable.

I hope this is on a list for future enhancements.
