HP41 FOCAL notation summary or cheat sheet?

[mfleming]

Hi everyone,

While working through HP41 manuals or code listings, I find notations for a program step I'm not familiar with from reading the calculator manual. For example, in the SandMath manual I see such statements as

ST+ X(3)
ARCL X(3)
STO IND Y(2)


Obviously over the years programmers have developed shortcuts to express a series of keystrokes, but it can be a pain for someone new to the machine to track down what is meant by the notation.

Is there some sort of quick summary or cheat sheet for this that you can direct me to? Perhaps a short reading list that will cover these and other example notations and how they are used? It certainly seems like a worthwhile article to introduce new owners to their calculator without retracing 35+ years of user development.

Any pointers appreciated! Thanks everyone,
