Description 
Use this script step to handle errors in a manner consistent with the functions the script performs. By using the Get(LastError) function immediately after a script step, you can verify that the step was performed properly.
By using the Get (LastError) function with the control script steps, you can make sure your script performs correctly. When you decide to suppress alerts, it is important that you anticipate as many problems as possible and include clear instructions for what to do when an error condition is encountered.
Notes
 •
Use Get (LastError) immediately after the script step you intend to test; a successful intervening step may clear the error code you were intending to capture.
 •
When Set Error Capture is used in a script that contains a sub-script, errors from the sub-script are captured as well.
Example 1 
Performs a find and suppresses the error dialog if no records were found.
Set Error Capture [On]
Perform Find [Restore]
Example 2 
Performs a find. If no errors occur, sorts records. If no find criteria were specified, shows all records. If no records match the find request, displays a custom dialog.
Set Error Capture [On]
Perform Find [Restore]
If [Get ( LastError ) = 0]
Sort Records [Restore; No dialog]
Else If [Get ( LastError ) = 400]
Show All Records
Else If [Get ( LastError ) = 401]
Show Custom Dialog ["Find"; "No records were found."]
End If
