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.
Note that under OS version 2.53MP (and presumably later), the chart below is off by one in most cases. For example, mGarbageCollect is $40 instead of $3F, and mGroupVars is $2A instead of $29. It has been confirmed that 2.55MP still contains this off-by-one bug.
