DALRTCTK requests that the JES Client Token (CTOKEN) associated with the SYSOUT allocation be returned to the caller of DYNALLOC. When you code DALRTCTK, # must be 1, and LEN must be hex '0050' (decimal 80) and PARM is an 80-byte field.
Dynamic allocation places the allocated CTOKEN in PARM upon completion of the associated SYSOUT allocation request.
When you specify DALRTCTK, you must also specify the SYSOUT key (DALSYSOU - X'0018').
KEY # LEN PARM
0071 0001 0050 --------- ... -------- 80 bytes in length
KEY # LEN PARM
0071 0001 0050 xxxxxxxxx ... xxx JES-supplied 80-byte CTOKEN
