:on_Error Label
on Error goto
Intention
:on_Error is a special Label. Its not a Label like any other!
If :on_Error is there, the script will jump there after an error and continue script execution there.
:on_Error does NOT prevent error messages, For this you have to use the USM.-command.
If :on_Error is really called, will also depend on the settings of an USM. - command.
Assume an error occurs and there is such a Label in a script. Then the robot will continue script execution in that line that is below that label.
The ":on_Error" Label does not prevent the Error-Message to be displayed, use the USM.10 command for that.
See more details and examples on error-handling here: 1.B Error handling .
