Generating the sample node error program

The sample node error program and table need to be translated, assembled, and link-edited. For information about the job control statements required to assemble and link-edit user-replaceable programs, refer to Assembling and link-editing user-replaceable programs.

Note that you should code the translator options NOPROLOG and NOEPILOG in your node error program.

Note also that an extra 24 bytes are required for the common subroutines register save area, and further space is required for the error processor save area. The CICS sample processors use 4 bytes of this area.

The DFHSNEP macro to generate the sample node error program has seven types, as follows:

TYPE=USTOR

to indicate the start of user storage definitions.

TYPE=USTOREND

to indicate the end of user storage definitions.

TYPE=INITIAL

to generate the routing mechanism and, optionally, the common subroutines.

TYPE=DEF3270

to generate the default CICS-supplied error processors for 3270 devices.

TYPE=DEFILU

to generate the default CICS-supplied error processor for interactive logical units operating in contention mode.

TYPE=ERRPROC

to indicate the start of a user-supplied error processor.

TYPE=FINAL

to indicate the end of the sample node error program.
