The Hooks are named by their hook pointer block address (the four bytes consisting of page, address, and an extra byte), in hexadecimal. An example is [[83Plus:Hooks:9B84]].

You must also include a variation on the following code to put your documentation into the appropriate Category listing:
 <nowiki>[[Category:83Plus:Hooks:By Address|8562 - ImAHook]]

This hook allows you to change the values that [[83Plus:BCALLs:4972|GetKey]] returns.

== Using the Hook ==
These different values, passed in a, determines what the hook should do.
* 1: The calculator just turned on. There seem to be no other values passed to the hook.
* 2: The calculator is computing 1+1.
** b: 1
** c: 1
** Change b and/or c to affect the output of the problem (which will still look like 1+1 to the user).
* 3: Preparing to turn off due to 2nd+OFF.
** Zero flag: Clear to abort the power off.

== Comments ==
This hook doesn't exist. This is a demonstration only.
