:: 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.
