After running through the nuisance of printing output and debugging, I have came up with these macro. It might be useful for you somehow :)
All bug free :) I hope the code is self-explained. But if there are any errors or things you want to add, please leave a comments :)
;useful macro callSome quick thing to note:
;make new line: printChar 10 printChar 13
;add a break point in your code that stop TurboDebugger when you hit F9: addBreakPoint
addBreakPoint macro
;save register
push AX
pushf ;AX=PSW
pop AX ;
or AX,0100h ;set 8th bit (trap flag)
push AX ;PSW=AX
popf ;
;restore register
pop AX
endm
printChar macro character ;print a character
;save register
push DX
push AX
mov DL, character ;
mov AH, 02h ;
int 21h ;
;restore register
pop AX
pop DX
endm
printMsg macro msgString ;print a message
;save register
push DX
push AX
mov DX, offset msgString ;print q1_1 string
mov AH, 09h ;
int 21h ;
;restore register
pop AX
pop DX
endm
- I tried doing CMP with 8-bit register and use the "less than" jump command, but it does not turn out as expected. Instead, JL only works when CMP is called for 2 16-bit register.
