>>Hi,

>>What is an example of a "bad" code that would produce error "File is not open"? I get an error report from a customer that shows this error message. The place is Init method of a form. I can't find what would produce this error. And I can't create a "test" line of code that would produce this error message. If I can produce this error maybe it will clue me on what is "wrong" in the Init method.

Nope,
that will generate an error like

Varirable LOC_MY_FILE is not found
