There are several ways to accomplish it. For instance, you could pass the first form as a parameter to the second:

* In form 1:
do Form2 with ThisForm, (additional parameters)

* Form2.Init():
* Save parameters, so they are available in all methods
lparameters toCallingForm, (additional parameters)
ThisForm.oCallingForm = toCallingForm
ThisForm.AdditionalParameter1 = ...

* Anywhere in Form2:
ThisForm.oCallingForm.AnyProperty = AnyValue

You could also save a reference to the parent form in a global variables.

HTH,
