SLEEP pauses the program indefinitely or for a specified number of seconds, program is unpaused when the user presses a key or when the specified number of seconds has passed.
- SLEEP [seconds]
- Seconds are an optional INTEGER value. If there is no parameter, then it waits for a keypress.
- Any user keypress will abort the SLEEP time.
- SLEEP does NOT clear the keyboard buffer so it can affect INKEY$, INPUT, INPUT$ and LINE INPUT reads.
- Use an INKEY$ keyboard buffer clearing loop when an empty keyboard buffer is necessary.
- SLEEP allows other programs to share the processor time during the interval.
Press a key... You pressed a key, now wait for 2 seconds. You've waited for 2 seconds. (or you pressed a key)
- Explanation: SLEEP without any arguments waits until a key is pressed, next SLEEP statement uses the argument 2 which means that it will wait for 2 seconds, any number of seconds can be specified.
