The Hello World Collection

This collection includes 441 Hello World programs in many more-or-less well known programming languages, plus 64 human languages.

The programs in this collection are intended to be as minimal as possible in the respective language. They are meant to demonstrate how to output Hello World as simply as possible, not to show off language features. For a collection of programs that tell more about what programming in the languages actually is like, have a look at the 99 Bottles of Beer collection.The Collection was compiled by Wolfram Rösler with help from many people around the world. It was started on 3-Oct-1994, put on the Internet on 30-Dec-1999, exceeded 200 entries on 14-Jul-2005, 300 on 6-Dec-2006, and 400 on 27-Jul-2008. It is now probably the biggest collection of Hello World programs on the Internet, and the only one collecting human languages as well. It is administered as a bunch of text files which are compiled into this single HTML file by a bash script executed under the Cygwin environment, run on Windows.

; This is a "Hello World" program for Z80 and TMS9918 / TMS9928 / TMS9929 /
; V9938 or V9958 VDP.
; That means that this should work on SVI, MSX, Colecovision, Memotech,
; and many other Z80 based home computers or game consoles.
;
; Because we don't know what system is used, we don't know where RAM
; is, so we can't use stack in this program.
;
; This version of Hello World was written by Timo "NYYRIKKI" Soilamaa
; 17.10.2001
;
;----------------------------------------------------------------------
; Configure this part:

DATAP: EQU #98 ; VDP Data port #98 works on all MSX models
; (TMS9918/TMS9929/V9938 or V9958)
; #80 works on SVI 
; (for other platforms you have to figure this out by your self)

CMDP: EQU #99 ; VDP Command port #99 works on all MSX models
; (TMS9918/TMS9929/V9938 or V9958)
; #81 works on SVI
; (for other platforms you have to figure this out by your self)
;-----------------------------------------------------------------------
; Program starts here:

ORG 0 ; Z80 starts always from here when power is turned on
DI ; We don't know, how interrupts works in this system, so we disable them.

; Let's set VDP write address to #0000

;
; Set mode selection bit M3 (maybe also M4 & M5) to zero and 
; disable external video & horizontal interrupt

The Infamous Hello World Program in Shakespeare.

Romeo, a young man with a remarkable patience.
Juliet, a likewise young woman of remarkable grace.
Ophelia, a remarkable woman much in dispute with Hamlet.
Hamlet, the flatterer of Andersen Insulting A/S.


                    Act I: Hamlet's insults and flattery.

                    Scene I: The insulting of Romeo.

[Enter Hamlet and Romeo]

Hamlet:
 You lying stupid fatherless big smelly half-witted coward!
 You are as stupid as the difference between a handsome rich brave
 hero and thyself! Speak your mind!

 You are as brave as the sum of your fat little stuffed misused dusty
 old rotten codpiece and a beautiful fair warm peaceful sunny summer's
 day. You are as healthy as the difference between the sum of the
 sweetest reddest rose and my father and yourself! Speak your mind!

 You are as cowardly as the sum of yourself and the difference
 between a big mighty proud kingdom and a horse. Speak your mind.

 Speak your mind!

[Exit Romeo]

                    Scene II: The praising of Juliet.

[Enter Juliet]

Hamlet:
 Thou art as sweet as the sum of the sum of Romeo and his horse and his
 black cat! Speak thy mind!

[Exit Juliet]

                    Scene III: The praising of Ophelia.

[Enter Ophelia]

Hamlet:
 Thou art as lovely as the product of a large rural town and my amazing
 bottomless embroidered purse. Speak thy mind!

 Thou art as loving as the product of the bluest clearest sweetest sky
 and the sum of a squirrel and a white horse. Thou art as beautiful as
 the difference between Juliet and thyself. Speak thy mind!

[Exeunt Ophelia and Hamlet]


                    Act II: Behind Hamlet's back.

                    Scene I: Romeo and Juliet's conversation.

[Enter Romeo and Juliet]

Romeo:
 Speak your mind. You are as worried as the sum of yourself and the
 difference between my small smooth hamster and my nose. Speak your
 mind!

Juliet:
 Speak YOUR mind! You are as bad as Hamlet! You are as small as the
 difference between the square of the difference between my little pony
 and your big hairy hound and the cube of your sorry little
 codpiece. Speak your mind!

[Exit Romeo]

                    Scene II: Juliet and Ophelia's conversation.

[Enter Ophelia]

Juliet:
 Thou art as good as the quotient between Romeo and the sum of a small
 furry animal and a leech. Speak your mind!

Ophelia:
 Thou art as disgusting as the quotient between Romeo and twice the
 difference between a mistletoe and an oozing infected blister! Speak
 your mind!

TI-59

 Back to index 

Hello World for the TI-59 with PC-100C thermo printer.
No comment character exists.

The TI-59/PC-100C can print up to 20 characters per line (upper case
only). They are coded as 2-digit decimal numbers (see manual for
details) in up to four print registers (of five characters each)
and then printed.
Before entering the program, press LRN to switch into learn mode.
After entering the program, cancel learn mode with LRN, turn on the
printer, and run the program with A.
A pleasant sound, and what a font! Real TRUE-TYPE!

The output looks like this:

      +--------------------+
      |        HELLO WORLD!|
