The PROC LOGISTIC doc states that PROC LOGISTIC uses BINWIDTH=0 for computing the association statistics. The PROC SURVEYLOGISTIC doc states that PROC LOGISTIC uses BINWIDTH=0.002 (=1/500) for a binary response. So if you want PROC LOGISTIC to agree with SURVEYLOGISTIC, you should use the BINWIDTH=0.002 option on the MODEL statement:
model Choice=LogPrice LogInc FamSize / binwidth=0.002;
The links above shows the formulas for computing the association statistics, which you can use if you want to compute the statistics "manually," as you said in an earlier post.
