Roi,

This would be much easier and cleaner, pass a reference to the object instead;

DO FormB WITH Thisform

In the formB Init you can;

LPARAMETERS poForm
Thisform.oForm = poForm && oForm is a custom property of the form.

Then anywhere you like within FormB you can;

Thisform.oForm.AArray(1,2) = "ABC"

And this gives you access to all the properties of FormA within FormB
