need help with debug.exe

[indianj]

hello everyone, i am taking assembly class where i need to use debug.exe program. i need help writing an assembly language program that accepts uppercase user input and converts it to lowercase in debug.exe?

here i wrote that program uses two functions: first one reads keyboard and second one writes on screen. It reads the keyboard characters until it finds a carriage return.

c:\>debug
-a100
178E:0100 mov ah,01;
178E:0102 int 21;
178E:0102 cmp al,0d;
178E:0106 jnz 0100;
178E:0108 mov ah,02;
178E:010A mov dl,al;
178E:010C int 21;
178E:010E int 20;
178E:0110
-w

I think that debug.exe only reads machine language, not human written x86 .
