Re: A83: Apps, adding to current menues


Well, yes.  The problem is that I haven't finished researching enough to
tell you a really nice, easy way to add things to a menu.  The original
author mentioned in the Interactive Graphing application, which adds stuff
to the window screen.  This is done using a graph hook, specifically:
2,(iy+35h)
9B90h - 9B93h

Now, adding things to the math menu is a little bit different.  I'm fairly
sure there's no math menu specific hook, and I suspect there to be a general
menu hook, but I don't know of it at the moment.  You could, however, use
one of the keyhooks to intercept the math menu and displays your own math
menu instead.  This is definitely the hard way to do things, since you have
to manually create the menu and send results back to the TIOS.  It's
definitely possible, since I've done it.

If there is a general menu hook, then that would be the easier way, but I
haven't happed upon it yet if it exists.
