| Set an environment variable in Windows 2000 |
| Windows 2000 and XP include most of the commands you're familiar with from DOS and Windows |
| 9x. But when Command Extensions are enabled—as they are by default—many of these commands |
| gain additional features. The DATE /T switch itself (which causes DATE to return without waiting |
| for input) is one such added feature. |
| Fortunately, you don't need to do a single thing to get the current date into an environment |
| variable. When Command Extensions are enabled, your batch files can access a number of dynamic |
| environment variables that return various system values. Specifically, the %DATE% and %TIME% |
| variables return the current date and time. You may also find uses for %CD% (returns the current |
| directory), %ERRORLEVEL% (returns the exit code of the most recent command) and |
| %RANDOM% (returns a random number from 0 through 32,767). Type SET /? at a command |
| prompt for more information. |
