In that case the string with the (now full length) three character
compare value would also need CMPBLAP(B).  So does that imply that
CMPBLAP is always "better" to use when comparing with constants?

I'm assuming here that if left without the pad and OPCODE was later
expanded to a longer length, that CMPBLA(B) ...,"SUB" would then match
any string which began with SUBxxxx.  Correct?  I gotta get myself one
of those MI Reference manuals...

Back in the days when I did assembler on some other machines, I'd
consider the instruction timing differences.  Today I can't imagine it
should justify a second thought from a performance standpoint.
