What you've got is a TSO call command.

R1 points to a list of fullword addresses, and in this case there will be only one. You load that first and only pointer into R4 with > L R4,0(R1) Now R4 points to a halfword length field(10), followed by the argument text - in your case "CLASS(USER". So far, so good. (At this point, I would just do a WTO with the TEXT= option. TEXT= takes a pointer to a halfword length followed by text, so you are all set.) Then there is some code that appears to confuse chaining save areas with the argument you've been passed... > ST R4,8(R13) > ST R13,4(R4) > LR R13,R4 > L R1,4(R1) If you want to include some hardcoded text such as "PARM1: ", then you might do better to reserve an area, e.g. MSG DS Y(*-*),CL256 move in your local constant text and the argument you received, make sure the length field covers both, and then issue the WTO TEXT=. You could even easily achieve reenterability this way, should that matter to you.
