Spitting out messages with formatted values was always a hassle for me
in assembler. So years ago I wrote some code to somewhat mimic printf,
and never looked back. Invoked by macros something like this:
#PRINTF SYSPRINT,'THIS IS LINE %D OF %D',VAR1,VAR2
#PRINTF SYSPRINT,'THIS IS STRING %S HERE',STR1
#PRINTF SYSPRINT,'DATA IS %08X',POINTER

For me, the challenge with learning assembler is how do you input and
output. I would have an assembler program called from a C program - and
teach them how to use the C "printf" function from assembler to output
data. The class can then focus on the assembler code, and get it working.
I learned the hard way, using the CMS PRY debugging tool to step through
the code, and look at the effect of the instructions.
