CICS Error Handling

Code Example

## CICS Error Handling

Handle exceptional conditions in CICS programs.

### RESP and RESP2
\`\`\`cobol
EXEC CICS command RESP(field) RESP2(field) END-EXEC
\`\`\`

### Common RESP Values
| Condition | Meaning |
|-----------|---------|
| NORMAL | Success |
| NOTFND | Record not found |
| DUPREC | Duplicate record |
| ENDFILE | End of browse |
| LENGERR | Length error |
| NOTAUTH | Not authorized |
| PGMIDERR | Program not found |
| MAPFAIL | Map receive failed |

### DFHRESP Function
\`\`\`cobol
IF WS-RESP = DFHRESP(NORMAL)
\`\`\`

### HANDLE CONDITION
Older style (avoid):
\`\`\`cobol
EXEC CICS HANDLE CONDITION NOTFND(label) END-EXEC
\`\`\`

### Best Practices
1. Always use RESP option
2. Check after every command
3. Log error details
4. Provide user feedback
