A Free42 (and HP42S) tricky question

I disagree. I do, in fact, use EDIT or EDITN programmatically sometimes.
For example, to create a 2x2 matrix populated with the numbers 1..4:

Code:

00 { 32-Byte Prgm }
01▸LBL "CRMAT"
02 2
03 ENTER
04 NEWMAT
05 EDIT
06 1
07 →
08 2
09 →
10 3
11 →
12 4
13 EXITALL
14 END

Of course you could also use INDEX, J+, and STOEL to achieve the same result, but using EDIT/EDITN and → can be more convenient.
