CICS® provides a user-replaceable node error program, DFHZNEP,
which assists the user in the following ways:
- It provides a general environment within which it is easy for
users to add their own error processors.
- It provides the fundamental error recovery actions for a VTAM®
3270 network.
- It serves as the default node error program (NEP),
where the user selects a NEP at system initialization.
The DFHZNEP program can be one of the following:
- The CICS-supplied default NEP
- A skeleton sample NEP generated using the DFHSNEP macro
- A user-written NEP generated using the DFHSNEP macro.
