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.

The '''_MOUSEX''' function returns the current horizontal(column) mouse cursor position when read after [[_MOUSEINPUT]].
|
|
|
|
|
|
{{PageSyntax}}
|
|
::: column% = '''_MOUSEX'''
|
|
|
|
|
|
''Usage:''
|
|
* SCREEN 0 returns the [[SINGLE]] horizontal text column position. Graphic screens return the [[INTEGER]] pixel columns.
|
|
* To calculate text columns in graphic modes divide the return by 8 or the [[_PRINTWIDTH]] of one [[_FONT]] character.
|
|
* [[_MOUSEINPUT]] MUST be used to detect any changes in the mouse position and is '''required''' for any coordinate returns.
|
|
|
|
|
|
''Example:'' A simple mouse drawing board using _MOUSEX and [[_MOUSEY]] coordinate values.
