Chapter 18 Error Controls

18-5

RESUME (Statement)

Function

Returns from an interruption process routine.

Format

RESUME [NEXT|<Label name>]

Explanation

This statement returns to the program before it has been branched from an

interruption process routine, as defined in the ON ERROR GOTO statement.

With RESUME NEXT, the program returns to the line following the line where

an error occurred.

With RESUME <Label name>, the program passes control to a designated

label line.

If you ignore all of the argument options in the RESUME statement, the

program returns to the line where the error occurred.

Remarks (1): 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.

Remarks (2): If the program returns to the line where the error

occurred, without removal of the error cause, the

program may execute an infinite loop.

Remarks (3): You cannot use this statement outside of the interruption

process routine.
