HP Prime: CAS Commands in Home Mode

[Helge Gabert]

Thanks so much!

And what would be the best way to pass a function or symbolic expression to a PPL program from the home view command line? I know that defining a function in CAS view first, say a(x):=x^2+2, works - - which then can be called by the CAS(" . . . a(x) ") construct in the PPL program. Alternatively, defining F0, . . . , F9 beforehand also works with CAS("solve(F1(x),x") etc.

But can I call the PPL program like TEST(X^2+2)? And have the PPL program
TEST(k)

. . . do something here with k, recognizing k is a function?

That doesn't seem to work.
