Component support of label processing

Job control statements make the label processing facilities of data management available to users of the operating system's assembler, linkage editor, Sort/Merge program product, utility programs, and high-level language program products. Table 1 shows the component support for each type of label processing.

Uses Data Management Facilities for Label processing Yes Yes Yes Yes Yes Yes Yes Yes
Supports Standard Labels (SL, AL) Yes Yes Yes SL-Yes AL-IEHINITT AL-IEBGENER Yes Yes Yes Yes
Supports Standard User Labels (SUL, AUL) No No Yes Yes SUL-Yes AUL-No SUL-Yes AUL-No SUL-Yes AUL-Yes No

  1. NSL can be specified only when installation—written routines that write and process the nonstandard labels have been incorporated into the operating system.
  2. If the BLP option is not allowed by the system, its use defaults to NL.
