Label - Goto

Declaration

<AMLABEL LABELNAME="text" />

Related Topics   

Overview

Sends task flow to the label indicated.

Practical usage

Used to direct the task to jump to a labeled section defined by the Label action. Make the Goto dependent on an If action or some other condition to avoid an endless loop between Goto and the label.

IMPORTANT: Excessive use of Goto can create tasks that are difficult or impossible to debug. If your task requires more than a few Goto steps consider re-structuring with sub-tasks (using the Start task activity). In many programming  languages, the use of even one Goto statement is considered bad programming practice.

Description

The following sample task checks if C:\Temp\test1.txt exists. If so, it is copied to C:\Monthly_Backup\Archive\test1.txt and a subsequent step stops the task. If not, the task skips to a label named bugHandler, at which point, a subsequent step displays File not found.
