Enables an error-handling routine after an error occurs, or resumes program execution.
On [Local] Error {GoTo Labelname | GoTo 0 | Resume Next}
\<emph\>GoTo Labelname:\</emph\> If an error occurs, enables the error-handling routine that starts at the line "Labelname".
\<emph\>Resume Next:\</emph\> If an error occurs, program execution continues with the statement that follows the statement in which the error occurred.
\<emph\>GoTo 0: \</emph\>Disables the error handler in the current procedure.
Local: "On error" is global in scope, and remains active until canceled by another "On error" statement. "On Local error" is local to the routine which invokes it. Local error handling overrides any previous global setting. When the invoking routine exits, the local error handling is canceled automatically, and any previous global setting is restored.
The On Error GoTo statement is used to react to errors that occur in a macro.
