For two examples of CAS programming, doing stuff that's only possible in CAS, see my D2F and PDQ programs in the HP Prime Software Library.

@Joe:
Maybe it could be helpful to add some more words about entering a CAS program, since I didn't find hints about creating a CAS program in the manual(s).
My way:
First in CAS mode I created an empty program like

Code:

d2f:=(x)->x

then I could edit this by [Shift]+1 (Program), and enter your code. Works fine, besides a small typo ('END;;').

Are there other steps to create/enter a CAS program?
Where did you find the operators like '/=' and '+=' ?
Again the manuals are unhelpful ;-)

Many thanks, Thomas
