There really is no such thing as a variable at this level (though an argument can be made that the registers are). CurRow/CurCol are really just two locations in RAM that are designated to be the coordinates the text-writing b_calls use. In assembly programs, what we designate as a label in the source just is a convenient way to tell the assembler a certain address.

So how do you designate one when using hex? (I really am not getting my point across because of the ineptitude of my programming jargon)

You make one up. There are a few sequential blocks of RAM that can be used as scratch memory when writing assembly programs; see page 28 in the TI-83+ Developer Guide I referred you to earlier ("Safe RAM Locations for Application Use") for examples.
