FILE()


Syntax:     FILE(<expC>)

Purpose:    To determine if a file exists in the Clipper path.

Argument:   <expC> is the file to locate and must include an
            extension.

            The filename may optionally be preceded by a path.

Returns:    A logical value.

            If the file exists, FILE() returns true (.T.).

Usage:      When FILE() executes, the current DOS drive and directory
            are searched first.  If the file is not found and no path
            was specified, the Clipper PATH is then searched.  In no
            case is the DOS path searched.

Library:    CLIPPER.LIB
