Assembly Programming - Hello World

CODE Goto start a100 JMP 112 ; ;112 MoV DX 102 ; ; ; MoV AH 9 INT 21 RET rcx 1A w q :Start DEBUG HELLO.CoM<%0.BAT :This is HELLO.BAT. IT MAKES HELLO.CoM I ran the BAT file and created the .COM file. Usually when I type "HELLO" at the DOS prompt nothing happens. But once I got an error message. Unfortunate I didn't write it down because I can't get it back up now. Anyone know what's wrong with this?

Hence you should ensure that 0x102 contains the String Hello World.

Did I think I already had something similar: CODE Goto start a100 JMP 112 ; ;102 DB 'HELLO WORLD!'0D 0A'$' ; ;112 MoV DX 102 ; ; ; MoV AH 9 INT 21 RET rcx 1A w q :Start DEBUG HELLO.CoM<%0.BAT :This is HELLO.BAT. IT MAKES HELLO.CoM I tried moving it to the same line too, like: CODE ;102 DB 'HELLO WORLD!'0D 0A'$' By the way, those are zero's not the letter 'O' if that helps?
