18.2 Error Interruption

ON ERROR GOTO (Statement)

Function

Interrupts when an error occurs.

Format

ON ERROR {GOTO|GO TO}<Label name>

Explanation

This statement defines and executes an interruption process routine when an

error occurs. If this interruption occurs, the program with the error process

routine designated with <Label name> is executed. To return from the error

process routine to the program, execute the RESUME statement.

When an error occurs while the error process routine is being executed, the

ongoivy program stops.

Remarks: This command has no meaning when “Error interruption

process code deletion” is set to ON (1) in [Program] of

[Project setting] of PAC Manager in WINCAPSII.

The same setting has been prepared in the teach pendant.
