is there a proc to run a z-test in SAS (differencce in proportions); thought there might be since there is proc ttest; else i thought i could modify proc freq or proc uninvariate.
if someone could guide me to SAS documentaiotn on this, would be much appreciated. been searching but can;t find anything.
i did the calc by hand (which was kinda fun); but would be good to know how to do this in SAS

No, that note is for comparing correlations. See this note for comparing proportions. As noted there, the chi-square test is equivalent to the Z test (just the square of it).
