RE: A83: Apps, adding to current menues


I'm not sure that I understand what you are saying.  Lets say that I wanted
to call a one page app called "THEAPP" when the user presses the shift key
and than the clear key (If that is possible).  What would the exact code be
the set this up.  If that key-combo is not possible, than what about if they
help the ON key and then pressed enter (which is somewhat like mirage's
ON+APPS key combo).  Thanks for your help so far.

Robby

P.S. How have you figured out all of this information?

Hmm...I guess it doesn't help you too much if you don't know how to activate
it, right?  To activate it, load the address of the hook into HL, then ROM
page of the hook into A, and then B_CALL $4F7B.  This is equivalent to
doing:
    ld    hl,hookaddr
    ld    ($9B88),hl
    ld    a,hookpage            ; or 'in    a,(6)' if you're on the hook
page
    ld    ($9B8A),a
    set    0,(iy+34)
