FoxPro System Information Function

ID: Q86908

The information in this article applies to:

Microsoft Visual FoxPro for Windows, versions 3.0, 5.0, 6.0
Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, 2.5a
Microsoft FoxPro for Windows, versions 2.5, 2.5a

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.
