remove further items from the stack to use as arguments. Thus, in the command
3 SENSOR-TYPE

SENSOR-TYPE
takes itself and

3
) off the stack, then performs its action on the
3

setting the configured sensor type to 3, representing a Güralp 3T sensor).

SAMPLES/SEC
,
clear the stack automatically after they execute.
