My first real calculator was a TI-85 and then an HP48GX when I saw it in 1994. I came in after the 42s and am slow on the pickup of a new language.

I will study your example and post back with questions.

In TI-85 land, the analog of indirect addressing would be using list/matrix indexes, e.g.

Code:

10->dimL D
For X,1,10
sin X->D(X)
End

In this case, the X is sort of like the register that you're using with "STO IND".

What is it in 48G land?
