If you will look at the FOXWEB documentation section: Processing user Input.  You will see an example involving a REGISTER and CANCEL button within a form.

 

I think that could be expanded to have buttons for NEXT,PREVIOUS,DELETE,ADD,EDIT,EXIT or anything else you need.

 

Then, in your ACTION FWX program, you simple detect which button was pressed and go from there ...

 

Just my thought after having just read the documentation.
