Total Posts: 1111 | In this list of opcodes, is "$" used to represent the current address of the JP or JR instruction? If so, is it even possible to define labels with just hex?

You can't define labels at all in programs, only apps. A label in a program is just a pointer for the assembler, it doesn't really exist in the program.

Total Posts: 1111 | Ok. I think this is the last thing I need to understand before I can do things: How, using nothing but instructions, would I go about manipulating the graph screen? Is there a certain address that the graph screen starts at? If so, what is the offset for each row?
If you could refer me to a resource that talks about it, that would be just as good.

Edit: All I know about that hex you just wrote is that there's a return at the end. By the way, never use C7. Bad opcode.

Total Posts: 1111 | I'll be back (at CG and other forums) in a week or less. I'm going to finish memorizing all the opcodes so I can program more efficiently.
