In V9, IBM is advertising the following format for the ARSSOCKD started task:
//ARSSOCK2 EXEC PGM=ARSSOCKD,REGION=0M,TIME=NOLIMIT,
// PARM='/-S -I ARCH850 -v'
minus capital S = start this instance
minus capital I = this instance name (just like always)
minus lowercase v = verbose or list out the options, same as specifying VERBOSE as in the previous append
This format is also good for V8.5.
I suggest that you may want to start rolling out this format now on 8.5 then you'll be comfortable with it when V9 gets implemented.
