Michael,

One of the best techniques I picked up from UT a long time ago
(Barbara Paltiel if I remember well) is to
pass an object reference as parameter. This way you can never go
wrong, or hardly ever.

Example : DO FORM NEXTFORM WITH This

Then, in NEXTFORM the first thing you do is store the object reference
you have been passed into a property of NEXTFORM, e.g. :

O_Calling_Control = Object_Reference_Passed (The THIS parameter of the DO FORM)

After that, within NEXTFORM, you can do anything you want, e.g.

This.Anything.Value = O_Calling_Control.Value

etc, etc,....
