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 '''_AXIS''' function returns the relative position of a specified axis number on a controller device.

{{PageSyntax}}
|
|
::: move = _AXIS(''axis_number%'')
|
|
|
|
|
|
* [[SINGLE]] values returned range between -1 and 1 as maximums and 0 indicating minimum or axis center.
|
|
* When the mouse is moved on the program screen, moves left or above center are negative while below or right are positive.
|
|
* The ''axis_number'' must be a number which does not exceed the number of axis found by the [[_LASTAXIS]] function.
|
|
* '''The number of [[_DEVICES]] MUST be read before using [[_DEVICE$]], [[_DEVICEINPUT]] or [[_LASTAXIS]]!'''
