Yes, EX is used to put varying lengths into instructions.
And if you are doing 4 or 8 groups of 8 nibbles and a blank into a
print line of 80 or 132,
do the unpacks then translate the bytes then move the blanks.
Yep, I think I'm converging ;-)
TR/MVC instructions have an LL field which may handle
up to 256 bytes, while UNPK use the LL field for both
source and target, up to 7 digits.
Which lead to a loop for UNPK, modulo 7, up to a complete
256 bytes buffer ready for "TR/MVC", modulo 256.
This should be the faster way, probably.
Lol ... more I understand of 370 arch more fun I get ;-)
