XMSDRV

Syntax:                 XMSDRV

Use:                    To determine the presence of the HIMEM.SYS driver.

Parameters:             XMSDRV

Returns:                The first character in the sending parameter will
                        have a "Y" if the driver is present in memory, and
                        a "N" if it is not present.  If you did not pass the
                        parameter correctly (e.g. FOXLIB = "ZMSDRV"), your
                        sending parameter will be unchanged.

Example:                . load c:\FOXLIB\xmsdrv
                        . FOXLIB = "XMSDRV"
                        . call xmsdrv with FOXLIB
                        . ?substr(FOXLIB,1,1) = "Y"
                        .T.
                        . rele modu xmsdrv

                        From this example, the HIMEM.SYS driver is present
                        in memory.
