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 '''PMAP''' statement returns the physical or [[WINDOW]] view port coordinates.
|
|
|
|
|
|
|
|
{{PageSyntax}}
|
|
:: PMAP (''coordinate'', ''function_number%'')
|
|
|
|
|
|
* The ''coordinate'' is the coordinate point to be mapped.
|
|
* The ''function'' can have one of four values:
|
|
|
|
:: 0 = Maps view port coordinate to physical x screen coordinate
|
|
:: 1 = Maps view port coordinate to physical y screen coordinate
|
|
:: 2 = Maps physical screen coordinate to view port x coordinate
|
|
:: 3 = Maps physical screen coordinate to view port y coordinate
|
|
|
|
* The four PMAP functions allow the user to find equal point locations between the view coordinates created with the [[WINDOW]] statement and the physical screen coordinates of the viewport as defined by the [[VIEW]] statement.
|
|
* Mouse co-ordinates returned by [[_MOUSEX]] and [[_MOUSEY]] are the physical screen co-ordinates.
|
|
|
|
|
|
''Example:'' Use PMAP to convert coordinate values from view to screen coordinates and from screen coordinates to view coordinates.
