Progress Procedure Syntax for VB Form

I have created a VB Form for tracking sales order reschedules. In this Form, I've created a field called "Original Due Date" that I want to be populated with the initial OrderRel.NeedByDate. I want the "Original Due Date" field to remain fixed as the OrderRel.NeedByDate changes.

Can anyone help me with the procedure syntax for this and tell me where I can find general information on Progress procedure syntax for future reference?

Thanks!
