No doubt, my favorite proc step is proc freq. It is extremely simple, but therein lies its beauty: it's fast to run and easy to understand. With just two lines of code (almost zero effort), it delivers a set of frequency output for all variables in one printout that anyone can understand, regardless of their involvement with the actual data set. I've found raw proc freq output to be a terrific starting point for conversations on data cleaning or data exploration, no matter who is involved in the conversation:
PROC freq data=NAME;
run;
PROC freq data=NAME;
run;
