ILE RPG Programmer's Guide
Planning the exception handling capability of your application
means making the following decisions:
- Decide if you will use the RPG-specific means of handling errors
(e.g., error indicator, 'E' extender, or error subroutine) or whether
you will write a separate exception handling routine which you will
register using the ILE API CEEHDLR. You might also choose to use
both.
- Decide on the recovery action, that is, where the program will
resume processing if you use a separate exception handling routine.
In addition, keep in mind the following when planning your exception
handlers:
- Priority of handlers
- Nested exceptions
- Default actions for unhandled exceptions
- Effect of optimization level
