Reusable Forms?

A2k (9.0.3821) SR-1

I have many similar variations of parent forms, sub forms and record search procedure that are the same as one another except for slight differences.

Trying to make forms as reusable as possible using open arguments to determine table lookup values for sub form names, field names that are then loaded into parent form module level public variables to be used throughout the form.

Are there any variable use considerations I should be aware of if delivering mde
