Writing your own node error program
You can write your own node error program (NEP) in any of the CICS-supported languages.
CICS provides NEP code is provided in assembler language, and the communication area parameter list is supplied in assembler language and C versions. The names of the supplied source files, copy books, and macros, and the libraries in which they can be found, are listed in Table 1.
| Name | Type | Description | Library |
|---|---|---|---|
| DFHZNEP0 | Program | Default node error program (assembler language) | CICSTS55.CICS.SDFHSAMP |
| DFHZNEPX | Source | Default NEP (embedded by DFHZNEP0 via COPY statement) | CICSTS55.CICS.SDFHSAMP |
| DFHSNEP | Macro | Sample NEP program generator (assembler language) | CICSTS55.CICS.SDFHMAC |
| DFHZNEPI | Macro | NEP interface generator (for multiple NEPs) | CICSTS55.CICS.SDFHMAC |
| DFHNEPCA | Macro | assembler language communication area | CICSTS55.CICS.SDFHMAC |
| DFHNEPCA | Copy book | C-language communication area | CICSTS55.CICS.SDFHC370 |
If you code in assembler language, you can use the sample NEP as a framework on which to construct your own node error program.
