I was playing with an idea that I found on TIBD. I thought that it would be really cool if we could open the string menu or Pic menu and have access to all 256 tokens. Sorry if I got your hopes up, because that has failed (so far). To get it to work, I might have to do a hackjob, but I did uncover a random tidbit of info.

When the OS calls your hook, if it is sending A=1, then you will want to exit with the z flag set. I do this with xor a \ ret. What I found was that we can change the token to be displayed from here without having to write a whole table. How do we do this? DE contains a extended keycode that maps to a token. All you have to do is change this value and the token that will be displayed gets changed. What I did, since my tokens were based on the menu item number and the token was arbitrary:
;E contains the Pic number
     ld d,60h            ;Start of a Pic token
     bcall(_TokToKey)    ;4A0Bh   Stores the extended key code to 8446h, A has the rest
     ld de,(8446h)       ;E know has the extended value
     ld d,a              ;DE now has the whole keycode
     xor a
     ret
I don't know where else this might prove useful, but have fun

Yeah, you can define your own table, but I was looking for a way to change only certain menu items without having to make a table. Of course, it probably would be easier to just use a table, but hey, it's good to have options

You can also use this idea when the hook is exiting (I think A=4) and you can change which token gets pasted.

Hmm, I assume you copied the table to RAM? I was looking at avoiding that Or is automatically copied to RAM? I haven't checked yet.

Yeah, the reason why I was avoiding that was because the menu was going to need 255 elements. I figured that it would be easier to draw the tokens based on a formula.
