Re: Re^3: Perl Operating System

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

Oh my, it has been so many years… `mov ah, 09h mov dx, offset msg int 21h ret msg db "ASM?$"` [download] (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".) Makeshifts last the longest.	[reply] [d/l]

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 :-) cheers tachyon	[reply]
