I have a dataset where I have to build a credit score model for bad customers. It is a logistic regression model. I want to build the model and thereafter test it. Can anybody tell me the sas code to split the data.

If you just want a 50/50 split then you could use something like:
data build validate; set sashelp.prdsale; if uniform(0) le .5 then output build; else output validate; run;

PROC SURVEYSELECT is typically used to generate random samples. If you want to do bootstrapping or any type of cross validation, I highly recommend the paper by David Cassell, Don't be loopy.
