Does the following from the VFP8 Help work...
---------------
Adding and Removing Forms
Once you've created a form set, you can add new forms and remove forms.

To add additional forms to a form set

From the Form menu, choose Add New Form.
To remove a form from a form set

In the Form box at the bottom of the Form Designer, select the form.
From the Form menu, choose Remove Form.
If you have a single form in a form set, you can remove the form set so that you have only the form.

To remove a form set

From the Form menu, choose Remove Formset.
Forms are saved in table format to a file with an .scx extension. When you create a form, the .scx table contains a record for the form, a record for the data environment, and two records for internal use. A record is added for each object you add to the form or to the data environment. If you create a form set, an additional record is added for the form set and for each new form. The parent container of each form is the form set. The parent container of each control is the form that it is placed on.

Tip When you run a form set, you may not want all forms in the form set initially visible. Set the Visible property to false (.F.) for forms you don't want displayed when the form set runs. Set the Visible property to true (.T.) when you want the forms displayed.
