Well done, but can you beat this "hello world!" for size ? , if so you would be optimising champion Wink

Code:

;*********************************; \\|//       Is it the smallest ?; (@ @)         "HELLO WORLD!"; ASHLEY4.         16 Byte's;; Assemble with Fasm.; c:\fasm hello.asm hello.com;; At the dos commandline type:; c:\hello hello world!;;*********************************        org   100h        use16        push  0xb800        pop   es        mov   si,0x81        mov   cl,13DoAloop:        lodsb        mov ah,9        stosw        loop DoAloop        ret

The normal try "hello world!" the best i can do is 21 bytes.

You should of entered the 512b compo, and then you may of bean 512b champion, the winner go in the hall of fame, and we have to call him/her SIR, on the forum.

Ok, this is strange:
Neither of the programs work(maybe its because of Windows) but
they act very differently.
The 16byte one doesn't print anything or
does it? (skips a line so I assume that at least 80 nonprintable
chars are there)
That 8byte one print some emty stace and some chars alltogether
92characters, but none of mine(same result with no parameters)

Hy,

well Madis731, it works under win98se, exactly it is writing the parameters passed to the com file by dos, what system do you have?
the 8 bytes one prints it via dos interrupt, so prints bytes from ds:81h to the first $ character. maeby you have parameters at a different address?

crc , you 're right, cause it is not really a hello world program, you could enter this at the command line too: echo Hello World! , so this way you don't need a com file anymore Smile

Hy,
i have made a real "Hello World!" program for those who were looking for a small one, i have even added a special feature: it even prints its own code before Hello World! , Smile

and all this at 20 bytes!

Code:

org 256
mov ah,9
mov dx,si
int 21h
ret
msg db 'Hello World!$'

of course it assumes si=$100 and uses dos print string function so it requres full dos compatibility.

Just checking you did type at the command line "hello hello world!" and assemble the program as a com file called "hello.com" ?

familiar?

Yes, and "hello hello world" didn't work either, but it does not matter what you write there.

That last one works fine: some garbish(your code) and then hello world

Hy all,
depending on the current poll votes:

Yes, if you don't change the docs
6% [ 1 ]
Yes, if you don't change the docs, and respect the author ( no words like shit, sux ... )
53% [ 8 ]
Yes, but only if you don't post it anywhere (internal use)
6% [ 1 ]
No, it is not fair to add your name to someone's compo, even if it whould fit in after the optimization
13% [ 2 ]
No, compo's are made by the author and are as is, and no subject to change, they're the way they meant to be implemented
20% [ 3 ]

i guess we can say most people don't mind if someone respects his/her code and modifies it.
however not many votes, but this might be because people were satisfied with the ratings.

if noone minds i will make some compos modified/enhanced by me a zip attachment with originals.
so if you have similiar things you can post them too.
