Remarks
SetEnv() lets you either append or replace a DOS environment variable from within an application. Typically this is configuration information-- including path names--that describes the location of files (database, index, label, or reports). Note: Instead of using environment variables for configuring your application, you may want to consider using registry settings.
Examples
These examples modify the DOS PATH:
X#
Copy
1? SetEnv("PATH","D:\CAVO2x\BIN", .F.)  //Overwrites PATH
2? GetEnv("PATH")
3? SetEnv("PATH", "C:\MyApp", .T.)  //Appends to the end of PATH
4? GetEnv("PATH")
