I think what happens is VFP interprets formname.tag as a table or cursor reference if the form object doesn't exist. If I try ?VARTYPE(formname.tag), the error returned is alias not found. IAC, it has behaved consistently for me in 9 as far as returning O for a form that exists or U or X for one that does not or is NULL. ymmv.
