FILE()

    FILE() verifies the existence of a specified filename and returns a
    logical True (.T.) if the file exists.

Syntax

    FILE(<exp C>)

Usage

    FILE() requires that the character expression input include both the
    filename and the file extension.  If the file resides on a different
    drive or directory than the default, you must either set a path using
    the SET PATH command or the drive and directory must be specified as
    part of the filename.  FILE() is not case-sensitive; any combination of
    upper or lower case letters in the filename is accepted.  Be aware that
    the DOS path is not searched.

    FILE() is useful in identifying a duplicate filename before information
    is stored to a file or for determining whether a needed file is
    available.
