This Natural profile parameter is available under z/OS and z/VSE only. It identifies the Natural subsystem to be used.

Possible settings 1 - 4 characters Natural subsystem.

Note:
If you specify less than 4 characters, blanks will be appended so as to get a 4-byte setting.

Notes:

  1. For the purposes of the Natural CICS Interface (see ROLLSRV, SIPSERV, SUBSID), the Natural profile parameter SUBSID is ignored if it is specified in a parameter string by a profile parameter SYS or PROFILE or in an alternate Natural parameter module (as specified with the profile parameter PARM).
  2. For information on the Natural subsystem, see Natural Subsystem under z/OS or Natural Subsystem under z/VSE in the Operations documentation.
