END DEF |
End Definition of Multi-line Function |
Use the END DEF directive to mark the end of a multi-line function.
In Execution mode, when PxPlus encounters a DEF FN directive for a multi-line function, it skips forward until it encounters an END DEF directive; that is, control is transferred to the line or statement after the end definition.
If you use an END DEF directive without a preceding DEF FN directive, PxPlus returns an Error #45: Referenced statement invalid.
