if tc.isEdit() then
    tc.cancelEdit()
endif

If your tc was updating an existing record then it will revert back to 
the original contents. If the tc was  inserting a record, the record 
will be discarded. UNLESS you issued a tc.postrecord which DID work then 
you'll need to do a tc.deleterecord(). Presumably you're just testing a 
tc.unlockrecord in which case a tc.cancelEdit() will handle it.
