Take a look at the proc freq documentation. One thing you will find is:

McNemar's test Beginning in Release 6.10, use the AGREE option in Base SAS PROC FREQ. Before Release 6.10, create a three-way table with a stratum variable identifying each subject (or matched group), a variable indicating each occasion (condition or individual within matched group), and a binary response variable. Then use the CMH option. For example, if each subject gives a binary response to each of two drugs, use the statement: tables subject*drug*response/cmh2 noprint;
