## Description
|
||
|
|
|
||
|
|
* Returns the number of axis that can be read on a specified device number within the number of [_DEVICES](_DEVICES) found.
|
||
|
|
* A valid number can be sent to the [_AXIS](_AXIS) function to find any relative axis movements.
|
||
|
|
* The devices are listed in a numerical order determined by the OS and can be read by the [_DEVICE$](_DEVICE$) function.
|
||
|
|
* **The [_DEVICES](_DEVICES) function must be read before using _LASTAXIS or an [ERROR Codes](ERROR-Codes) will occur.**
|
||
|
|
* Devices include keyboard(1), mouse(2), joysticks, game pads and multiple stick game controllers.
