Why not also allow the EXreg instruction to execute UP TO 8 bytes worth of
the register contents? In other words, if you have less than 6 byte
instructions to execute (say a 2-byte plus a 6-byte instruction) why not allow
BOTH of them to potentially execute within the single EXreg instruction?
Then why not also allow an EXreg-multiple instruction to support up to 16 (or
15) registers worth of instructions preloaded into the registers to operate,
much like the PDPs of old did? (Not that slow, of course.)
Or just leave it all alone and be grateful that Ed got his wish.

Let's all quit trying to second-guess IBM and instead just wait a while.
I'm certain that there will be additional upgrades as the z/10 goes
through evolution. Let's see what time brings us.
