SUMMARY
=======

The SYS functions provide system information about a Microsoft FoxPro
installation. The values SYS(2011) through SYS(2021) are new to FoxPro version
2.0.

To query system information interactively, enter

     ? SYS(#)

in the Command window, where "#" represents the appropriate function number. For
example, ? SYS(9) returns the FoxPro serial number. The returned value is
displayed in the last cursor position of the active window, or by default the
return value is displayed in the lower-left corner of the screen.

Another method of checking system information is to use the following:

     WAIT WINDOW SYS(#)

where "#" represents the appropriate function number. Or you can place SYS(#) in
the Debug window.

These alternative methods offer at least one advantage over the ? SYS(#) method
since the ? SYS(#) method writes to the last cursor position for the active
window, and it is possible to have other objects obscure the output of the ?
SYS(#) command so that you can't see where the returned value is being
displayed.

The output from the WAIT WINDOW SYS(#) method is displayed at a predictable
location in a predictable fashion. If the Debug window method is used, the
output is displayed in the Debug window.

For more information, see pages 3-874 through 3-891 of the "Microsoft FoxPro
Commands & Functions" manual for version 2.0, or see pages L3-1065 through
L3-1083 of the "Microsoft FoxPro Language Reference" manual for version 2.5.
