Assembler - .Model Tiny

MR. ROBOT

A little bit of assembler to honour one of my favourite series at the moment.
This time in the old 16-bit fashion of DOS coded in DEBUG.EXE

Output: Mr.Robot

Offset 0x100 [COM header] .Model Tiny Coded in DEBUG.COM 16bits

100 mov dx,10a // Hold the initial offset memory value for the loop
103 mov al,4d // “M” [write char] 
105 mov ah,0e //BIOS function to write a character to screen
107 int 10;   //BIOS interrupt/call
109 add dx,4 // Add 4 bytes to the 10a jmp memory address for the loop
10C jmp dx // [Offset change +4]
10E mov al,72 // “r”
110 jmp 105 // [GOTO write char]
112 mov al,2e // “.”
116 jmp 105 // [GOTO write char]
