Basically, calls using "CAS.<func>" no longer auto-evaluate the first argument. The reason for this is that you can now store and use local variables directly. Auto-evaluating would make that impossible.
When you have a string you'd like to evaluate *before* your CAS call, put in the EVAL function.
CAS.numer(f,"x"); ----> CAS.numer(EVAL(f),"x");
Before, that EVAL always happened no matter what. Now, you need to manually do it.
