Keystroke Programming: Labels vs. Line Numbers

[r. pienne]

I use both a physical 35s, and Free42 on my phablet.

The labelling system used by the 35s (typical use LBL A, XEQ A, GTO A123) is simple and neat, and makes possible the construction of long complex programs.

The 42s/Free42 system is obviously more powerful as it allows three forms of label (local 2-digit numeric, local single-letter in ranges A..J and a..e, or multi-letter global), but in my view a bit scattered. Numeric labels can be easily confused with line numbers; single-letter locals are limited; and you just don't put global labels inside a program.

I don't expect computer-grade facilities in a calculator. Both the 35s and 42s offer good power in a traditional package. For anything more, I'll use a computer.
