Unless you're willing to use NULLs as the parameter value for "all projects", (Which I'm not sure VFP will allow), you'd have to use two parameters to test this.

Select * from mytable where ISNULL(?vp_terminated) OR (mytable.terminated = ?vp_terminated)

Select * from mytable where IIF(?vp_allprojects,.T.,.F.) OR (mytable.terminated = ?vp_terminated)
