Label - Goto

Declaration

<AMLABEL LABELNAME="text" />

Related Topics   

Description

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 it is recommended to 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. Use at your own risk!

  • To successfully run the sample code, update parameters containing user credentials, files, file paths, or other information specific to the task to match your environment.

Description

This sample task checks if C:\Temp\test1.txt exists. If so, it will be copied to C:\Monthly_Backup\Archive\test1.txt and a subsequent step stops the task. If not, the task will skip to a label named bugHandler, at which point, a subsequent step will display a message dialog stating "File not found!"
