Changes in the SYS(0) Function in Visual FoxPro (141949)
The information in this article applies to:
- Microsoft Visual FoxPro for Windows 3.0
- Microsoft Visual FoxPro for Windows 3.0b
This article was previously published under Q141949 SUMMARY
In earlier versions of FoxPro, the SYS(0) function returned a name from the
network such as the UserName from Novell. Many developers used this
function to determine the login of the user, to keep track of who had which
files open, and so on.
In Visual FoxPro, the SYS(0) function does not look to the network. It may
return all pound signs or it may return an unexpected name, depending on
how Windows is set up.
In Visual FoxPro 3.0, SYS(0) returns information from the Windows
configuration files. In Windows for Workgroups, it returns the ComputerName
and UserName from the [Network] section of the System.ini file. In Windows
95, it returns the ComputerName and what seems to be the first login name
from the Registry. (In other words, if you logged into two different
servers with two different login IDs, Sys(0) would only return the first
one.)
This behavior is by design, in order to make the function more compatible
with a larger number of networks.
