ON-ERROR Opcode In IBM i

This video explains how to use the ON-ERROR and MONITOR opcodes in AS400 RPGLE for robust error handling. Key points covered: 1. MONITOR identifies errors during program execution. 2. ON-ERROR defines actions to take for specific error codes or conditions. 3. The video demonstrates handling three error scenarios: File not open (error code 1211) - attempt to open the file. Update without prior read (error code 1215) - perform a read operation first. Any unhandled file error - display an error message and dump program state. By leveraging ON-ERROR and MONITOR, you can create more reliable and resilient AS400 programs that gracefully handle errors. For detailed description and explanation refer the E-Book.
