No, L from address 16 is correct.
There are other things you can get from
various system control blocks, for example
the DDNames in the TIOT (task IO table),
but all those activities start with the fullword at address 16.
Look here:
L R1,16 CVT POINTER
L R1,0(R1) TCB TABLE
L R1,4(R1) OWN TCB
L R1,12(R1) ADDRESS OF TIOT
AHI R1,24 ADDRESS OF FIRST DDNAME
LA RF,0 RETURN CODE
SR R0,R0
LOOP WHILE,(0(R1),NE,0)
BREAK (4(8,R1),=,=CL8'SUCHDDN')
IC R0,0(R1) LENGTH OF DD-ENTRY
AR R1,R0 NEXT DD-ENTRY
OUT NOTFOUND
LA RF,4
ELOOP
looks for DDName SUCHDDN in the Task-IO-Table.
Returns with zero in RF, if found, and 4, if not found.
Kind regards
Bernd

I don't have an answer to your questions, but I think you mean
LA 15,16
