Added new _STRCMP and _STRICMP commands for quick string comparisons. Cleaned up QB64 to finish removing the QUI (quick user insert) code and folders. Altered UCASE and LCASE routines to be faster in some situations for us.

:: 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.
