System Level Procedures

Implicit NCL execution also occurs in relation to the various system level procedures that operate internally. The most common examples are:

LOGPROC

This process executes the NCL procedure nominated on the SYSPARMS LOGPROC= command. The process executes in the processing region of the LOGP user ID type, which is a virtual user. LOGPROC views, and can act on, all messages that flow to the log.

PPOPROC

This process executes the NCL procedure nominated on the SYSPARMS PPOPROC= command. The process executes in the processing region of the PPOP user ID type, which is a virtual user. PPOPROC views, and can act on, all unsolicited messages that are sent to your product by VTAM to report network events.

Other system level procedures can be started by optional components, for example, the Network Error Warning System (CNMPROC).
