| When programming assembly through the calculator's program editor, all a bcall is is EF address. Where can I find the hexadecimal addresses of at least some common bcalls? |

| Have a look in the 'ti83plus.inc' file. |

Thanks  . what does ;*** mean?
Edit: I had no idea there were so many bcalls!!
Edit Edit: That raises a problem however. The reason I needed this was to program without a computer. There are just too many bcalls to print all of them - could someone find or get me a printable list of the most useful bcalls?

Solution, copy and paste the ones you use most frequently. 
Also if you didn't know, when typing out a program in hex on the calc you must reverse the bytes of the address. LSB first.
Example.
bcall(_GetKey)
_GetKey is equated as 4972h
So in hex, you would type this.
EF7249
_____________________________________________________
This is the same for load instructions, and the call instructions.
ld hl,PlotSScreen
PlotSScreen is equated as 9340h
Once again in hex.
214093
_____________________________________________________
It is also not recommended to make elaborate programs in hex. Unless of course you want to sit there with a list of all the z80 op codes/ ram equates/ ROM calls /Key Equates.....etc, etc. To try and decipher your code. I suggest you use Chasm for on calc programming, but I must warn it is not the most stable, and not exactly user friendly for beginners. |

Yes, but could you (or anyone else) suggest a list of several to start with?

I use Omnicalc's disassembler + a list of most functions translated <-> hex I wrote out using said disassembler. Plus it far faster to use the slow way at school (7 hours a day) than the fast way at home (no more than 1 hour a day). Maybe when TitanAsm comes out (if ever  ) I'll do things differently.

It means that that ROM call didn't always exist, or wasn't always "official".

There is (potentially) one every three bytes from $4000 to past at least $8000. There are quite a few that aren't defined in TI83PLUS.INC.

That depends on what you think is "useful". |
