In A51 the next definitions takes two cells of RAM, (0AH), for example, and (0BH): data_variable: DS 1 typeless_number EQU 0BH and can be treated with the same instruction: MOV A,data_variable (F50A) MOV A,typeless_number (F50B) ,but there is the value of "data_variable" displays properly in the "Watch" window, "typeless_number" shows it's address instead of the value. How can I trace such a variable?
I think the question is not in difference between EQU/define/DATA et cetera But it's exactly about the difference between EQU and DS! And the difference between those is precisely that one generates a number, the other a variable. This difference both neatly explains the difference of behaviour if one tries to display things in the debugger (the EQU is not displayed as "its address", but actually as itself: a number), and provides an obviously correct solution to the problem: don't use EQU if what you wanted was to define a variable. Now, even an EQU-ed "variable" can be viewed in the debugger, but you'll have to go through quite some painful typing to get there. You'd have use something like
*(data char *)equ_label
