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.

|

|
|
* $SCREENHIDE may be used at the start of a program to hide the main program window when using a [[$CONSOLE|console]] window.
|
|
* $SCREENHIDE must be used before the [[$SCREENSHOW]] [[Metacommand]] can be used!
|
|
* The [[_SCREENHIDE]] statement must be used before [[_SCREENSHOW]] can be used in sections of a program.
|
|
* '''QB64 [[Metacommand]]s require that commenting or [[REM]] NOT be used!'''
