DISKREADY()

Syntax:     DISKREADY(<expC>)

Arguments:  <expC> denotes the drive designator (A,B,C etc.) to be
            tested.

Returns:    A logical value.
            The designated drive is ready to operate if the return value
            is (.T.).

Usage:      It is frequently necessary to  distribute copies among several
            disks because of space restrictions.  DISKREADY() can be
            used to await a complete change of disk, without having to
            be either confronted with the known DOS errors or having
            to use Clipper's error trapping routines.

Notes:      The function defaults to the current drive if <expC> is not
            passed.

Library:    CT1.LIB
