Are you using SAS UE? If so, I don't think HP procedures are available.

Beside to @Reeza's answer, I have general remarks:

when you need help with writing a code program - post yout code

when you have error while running - post your log, thus displaying the code and the error message

when you doubt about how to deal with your data - post a sample of input data, your wanted output and your code

It depends on the model. Proc score exists as well as a CODE statement in various procs.

If you are using PROC HPSPLIT , check CODE statement.

proc hpsplit ..........
......
code 'score.sas';
....

data want;
 set test;
 %include 'socre.sas';
run;
