The Allow User Abort script step affects the script that it is executed in and all sub-scripts.
By default, users can stop a script by pressing Esc or Command-.(period) (OS X). To prevent users from stopping a script, use the Allow User Abort script step and set it to Off.
By default, unknown (obsolete or unrecognized) script steps will stop a script. To change this behavior, set the Allow User Abort script step to one of the following. In either case, unknown script steps return FileMaker Pro error 4 (“Command is unknown”).
On (default) allows unknown script steps to stop the script
Off skips unknown script steps and allows the script to continue to run
Clients can’t abort server-side scripts or scripts performed via Custom Web Publishing. In these cases, this script step determines only whether unknown script steps are skipped.
Example 1 
Displays the records in the Print Invoices layout in a new window in Preview mode and pauses the script. You can click Continue to print the invoices, or you can cancel printing in the Print dialog box because in the Print script step, the With dialog option is On. Allow User Abort is Off so that you aren't left with an extra window open if you cancel the script.

New Window [Name: "Print Invoices"; Style: Floating Document]
