You can use proc tranpose for that, very simple:

proc tranpose data=have out=want prefix=resp_;
  by id cp;
  var resp;
  id source;
run;

Note assumes sorted by the by variables. Post test data in the form of a datastep next time.

Also, unless this is for a report output, it is really not recommended to program in this way, it will make all your program from that point on much harder, and you have increased the difficulty even more by affixing a character as the end, thus you will struggle to even use lists and such like, e.g. var1, var2, can be a list of var:.
