timer
Sets a timer to use with the wait for command. The timer command performs a Windows SetTimer() command. When the timer fires, the script processor goes to the label specified by on error (if any). The script exits immediately if no label has been specified by on error.
Usage example:
timer: 100
The argument is the number of tenths of a second to wait. The example sets a timer for ten seconds. See the example in the goto command for another example.
To switch off a timer, use the following:
timer: 0
For an example of timer in context, see wait for.
