Does anyone know how to edit the source code for .asm programs. (i.e. I have a file called Ztetris.asm and I don't know how to edit the code) also, does any know how to make a graph link do what it is meant to do (send between computer and calc) I keep getting Transmission errors and "Link Error-Check your link connections...." and of course, my link connections are fine. Thanks for any help....
