David,

It seems your object is a form. One way to realize your goal is to use a parameter object.

loParm = CreateObject("MyParmClass")

loForm = CreateObject("MyFormObject",loParm)
loForm.Show()

...

somevalue = loParm.SomeProperty
loParm = NULL

MyParmClass would be a class defined with the property SomeProperty added to it (the base class is irrelavent). You recieve the parm object in the form's init and save a reference to it in a form property (which you have added to the form class for that purpose).

* Form's Init
LPARAMETERS poParm
This.oParm = poParm

Then from within the form you can refer to the parm object as Thisform.oParm.SomeProperty.

The big advantage of using this technique is that you are virtually unlimited on how many properties the parm object can have. Some can be values being passed into the form and others values returned by the form. Some of the properties of the parm object can even be arrays full of values.
