As to converting bin to hex, I remember being asked multiple times why I
had a constant defined so:

TRTAB DC '0123456789ABCDEF"

thought of that!" after my explanation.

Did you then add a comment like "Don't ask. Think."? I would have.

(Oh, and I may be out of practice, but shouldn't the quotes be balanced?)

TRTAB DC '0123456789ABCDEF'

Does it tell you anything that I spaced to cols 10 and 16 without even
thinking about it?

I don't want to discourage people from asking, whough I do want to
encourage them to think. It's a knife-edge.

I saw a hex format routine in PL/I, once. It was lots messier, involving
pulling the next character off the hex string and using it as an index
into the same array. Ugly. And I suspect it could have been done lots
less messily. I never wrote any production PL/I, thank goodness.
