perhaps I misunderstood the question... I believe the question was to have a unique ID for a particular form not for each control on that form.

If the request is for a unique ID for each control on that form then it would be simple matter to add the object's full name to the string for each control... since a form cannot have two objects of the same name then that might would work. Or simply add a second SYS(2015) to the end of the string for each control.
