MACHINE=(,NOLIST) seems to turn on all current op codes.  MACHINE=(,LIST) will 
give you a list of all op codes supported.  
MACHINE=(ZS-4,NOLIST) limits op codes to those available on a Z10.

IOW, is there a new value for the operand of the OPTABLE instruction, or
is that also to be found in the P[ro]Op?

And, did zEC12 indroduce no new addressing modes nor instruction
formats that might affect syntax described in HLASM doc?
