Declaration

<AMLABEL LABELNAME="text" />

Description

Labels a point in a task with a specific name. Can be used with the Goto action or On Error Goto to direct task execution to a different point of the task.

Practical Usage

This action does not have an effect on task execution, it only defines a point in a task. Please see Goto activity for usage information.

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!

Example

NOTE:
  • The sample AML code below can be copied and pasted directly into the Steps Panel of the Task Builder.
  • Parameters containing user credentials, files, file paths, and/or other information specific to the task must be customized before the sample code can run successfully.

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!"
