It seems to behave properly when using a variable. (sometimes) I was checking for form instantiation, which shouldn't be any different.

Here is a code snippet from my method:

do form (lcFileName) name .aForms[.nFormCount] linked noshow

**-- Test to see if the form is actually instantiated /DAO/
*
if vartype(.aForms[.nFormCount]) != 'O'
return(.F.) && No form
endif

If the form exists, everything is fine, if not, and the array index is undefined, it errors out whereas, type() used in the same manner, behaves properly.
