== Synopsis ==
'''Official Name:''' MenuCurrent

'''Memory Address:''' 85DEh

'''Length:''' 3 bytes.

This area of memory stores the value of the current TI-OS menu.


=== Description ===
* '''MenuCurrent:''' contains a value for the type of menu (e.g. [PRGM], [MATH]). Note that the corresponding sub-menus are also equivalent to their respective menu (e.g. [PRGM] is also the same value as [DRAW])

* '''MenuCurrent+1:''' contains which header is selected (e.g. [NUM] in the [MATH] menu).

* '''MenuCurrent+2:''' tells us which item in the menu is selected.


== Comments ==
Bytes two and three (the header and item) are zero-indexed, so item #1 is $00, item #2 is $01, etc.

Once a menu is exited, these bytes are reset.

== Equates ==
Here is a list of equates related to MenuCurrent and MenuCurrent+1:
