DFHZNAC executable module

The node abnormal condition program is attached by DFHZACT when an error in communication with a logical unit occurs. DFHZNAC performs the following functions:

• Analyzes abnormal conditions
• Sends appropriate messages to the CSNE transient data destination
• Invokes the user-supplied (or sample) node error program
• Takes the appropriate actions resulting from the defaults which may have been modified by the node error program.

DFHZNAC consists of the following copybooks:

DFHZNCA  - Primary error action table and exits
DFHZNCE  - Take action routine
DFHZNCS  - Sense decode routine
DFHZNCV  - z/OS Communications Server return code routine.
