On z/OS, List All Of Your Options In SYSOUT

[Ed_Arnold]

New in 8.5.0:

//ARSSOCK2 PROC                                                
//ARSSOCK2 EXEC PGM=ARSSOCKD,REGION=0M,TIME=NOLIMIT,            
// PARM='/VERBOSE ARCH850'

Use the VERBOSE parm and as soon as ARSSOCKD starts up you'll see:

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.
