DEBUG.exe no more

this is old stuff. debug.exe let you write assembly instructions in DOS and execute them. i was told it will no longer be on windows operating systems i think the 64 bit versions.

here is some code to print A-Z with spaces between.

a
MOV AH,02
MOV DL,41
CMP DL,5B
JE 0114
INT 21
MOV DH,DL
MOV DL,20
INT 21
MOV DL,DH
ADD DL,01
JMP 0104
RET

g
q
