I have a form I have developed and I want to make it part of a page frame so I can have the user switch between forms using the tabs along the top. What is the best approach for developing such a form?

1) Create separate forms until they work independently and then combine them into one

or

2) Add the page frame control, move the existing form controls to the first page and then add new pages and work on them as part of the page frame

or

3) some other approach

Thanks in advance from a VFP newbie.
