It's interesting - the object ref exists and ISNULL() returns .f. - but the control is not a member of the Container Textbox2's Controls or Objects collection. The test scenario was to create the defines as shown do a SET PROC TO prg containing defines. I then created a base form and added the following to the Init:

thisform.addobject('testbox','testbox')

prior to running the form, I did the following to expose the _Screen object in the locals:

oSc = _screen

I then ran the form, and explored the collections through the object ref.
