Re^3: Perl Operating System

Though it would look less awful if you had used a string output function instead of one-character-at-a-time I/O. And been smaller, too. (Also: eww, DOS.)

Can we also fight over AT&T-style vs Intel-style mnemonics?

Ahhhhh!!! Assembler GOLF! 21 bytes.... OK so I admit I did not try to make assembler look good. I have always liked the thought that C is a language with all the power of assembler, but with all the user friendliness of ..... assembler.

jmp start
msg db "ASM?$"
start:
mov ah,09
mv dx,offset msg
int 21h
mov ah,4ch
mov al,00
int 21h

[Aristotle]

Oh my, it has been so many years…

mov ah, 09h
mov dx, offset msg
int 21h
ret
msg db "ASM?$"

(The ret is a CP/M remnant. There's an int 20h at the top of the program segment prefix and DOS puts a 0000 word on the stack before it passes control to the program. We are now deep in the dark ages of microcomputer "operating systems".)

When VB came out I lamented ignoring my once well honed BASIC skills. With Delphi I almost convinced myself that Pascal was not really as bad as I remembered. Stirring up Abigail-II has been the only *honest* use of very rusty ASM skills in nearly 20 years :-)
