Transwiki:List of hello world programs
From Wikibooks, the open-content textbooks collection
The following is a list of Hello, world! programs.
Hello, world! programs make the text "Hello, world!" appear on a computer screen. It is usually the first program encountered when learning a programming language. Otherwise, it's a basic sanity check for an installation of a new programming language. If "Hello World" won't run, one must not try and develop complex programs before fixing the issues with the installation.
[edit] 4DOS batch
It should be noted that the 4DOS/4NT batch language is a superset of the MS-DOS batch language.
@echo Hello, world!
[edit] Ingres 4GL
message "Hello, world!" with style = popup;
[edit] ABAP - SAP AG
REPORT ZELLO. WRITE 'Hello, world!'.
[edit] ABC
WRITE "Hello, world!"
[edit] ActionScript 1.0 and 2.0
This will output to the output window only, which an end user would not see.
trace("Hello, world!");
This version will be visible to the end user. Use of _root to clarify scope only.
var helloWorld:TextField = _root.createTextField( "helloWorld", _root.getNextHighestDepth(), 1, 1, 100, 20 ); helloWorld.text = "Hello, world!";
[edit] ActionScript 3
package { import flash.display.Sprite; public class HelloWorld extends Sprite { public function HelloWorld() { trace("Hello, world!"); } } }
[edit] Ada
with TEXT_IO; procedure HELLO is begin TEXT_IO.PUT_LINE ("Hello, world!"); end HELLO;
For explanation see Ada Programming:Basic.
[edit] ALGOL 68
In the popular upper-case stropping convention for bold words:
BEGIN
printf($"Hello, world!"l$)
END
or using prime stropping suitable for punch cards on 6 bit character platforms:
'BEGIN'
PRINTF($"HELLO, WORLD!"l$)
'END'
or minimally using the "brief symbol" form of begin and end.
( printf($"Hello, world!"l$) )
[edit] AmigaE
PROC main()
WriteF('Hello, world!');
ENDPROC
[edit] AMX NetLinx
This program sends the message out via the Diagnostics Interface after start-up.
program_name = 'Hello' define_start send_string 0,'Hello World!'
[edit] APL
An explicit return function for the Hello, world! program may be coded as follows (note: TeX fonts are not correct)
- The Del on the first line begins function definition for the program named HWΔPGM. It is a niladic function (no parameters, as opposed to monadic or dyadic) and it will return an explicit result which allows other functions or APL primitives to use the returned value as input.
- The line labelled 1 assigns the text vector 'Hello, world!!' to the variable R
- The last line is another Del which ends the function definition.
When the function is executed by typing its name, the APL interpreter assigns the text vector to the variable R, but since we have not used this value in another function, primitive, or assignment statement the interpreter returns it to the terminal, thus displaying the words on the next line below the function invocation.
The session would look like this
HWΔPGM
Hello, world!!
While not a program, if you simply supplied the text vector to the interpreter but did not assign it to a variable it would return it to the terminal as output. Note that user input is automatically indented 6 spaces by the interpreter while results are displayed at the beginning of a new line.
'Hello, world!'
Hello, world!!
[edit] AppleScript
See also GUI section.
return "Hello, world!"
[edit] ASP
<% Response.Write("Hello, world!") %>
- or simply:
<%= "Hello, world!" %>
[edit] ASP.NET
// in the code behind using C# protected void Page_Load(object sender, EventArgs e) { Response.Write("Hello, world!"); }
// ASPX Page Template <asp:Literal ID="Literal1" runat="server" Text="Hello World!"></asp:Literal>

[edit] BASIC
[edit] General
The following example works for any ANSI/ISO-compliant BASIC implementation, as well as most implementations built into or distributed with microcomputers in the 1970s and 1980s (usually some variant of Microsoft BASIC):
10 PRINT "Hello, world!" 20 END
Note that the "END" statement is optional in many implementations of BASIC.
Some implementations could also execute instructions in an immediate mode when line numbers are omitted. The following examples work without requiring a RUN instruction.
PRINT "Hello, world!"
? "Hello, world!"
Later implementations of BASIC allowed greater support for structured programming and did not require line numbers for source code. The following example works when RUN for the vast majority of modern BASICs.
PRINT "Hello, world!" END
Again, the "END" statement is optional in many BASICs.
[edit] BlitzBasic
Print "Hello, world!" WaitKey
[edit] DarkBASIC
PRINT "Hello, world!" `or TEXT 0,0,"Hello, world!" WAIT KEY
Note: In the "classic" Dark Basic the WAIT KEY command is optional as the console goes up when the program has finished.
[edit] Liberty BASIC
To write to the main window:
print "Hello, world"
Or drawn in a graphics window:
nomainwin open "Hello, world!" for graphics as #main print #main, "place 50 50" print #main, "\Hello, world!" print #main, "flush" wait

[edit] TI-BASIC
On TI calculators of the TI-80 through TI-86 range:
:Disp "Hello, world! (note the optional ending quotes) or :"Hello, world! (only works if on last line of program) or :Output(X,Y,"Hello, world! or :Text(X,Y,"Hello, world! (writes to the graph rather than home screen) or :Text(-1,X,Y,"Hello, world! (only on the 83+ and higher, provides larger text, home screen size)
Note: "!" character is not on the keypad. It can be accessed from "Catalog" or the "Probability" menu (as factorial notation).
On TI-89/TI-89 Titanium/TI-92(+)/Voyage 200 calculators:
:hellowld() :Prgm :Disp "Hello, world!" :EndPrgm

[edit] PICK/BASIC, DATA/BASIC, MV/BASIC
In addition to the ANSI syntax at the head of this article, most Pick operating system flavors of Dartmouth BASIC support extended syntax allowing cursor placement and other terminfo type functions for VDT's
X, Y positioning (colon ":" is the concatenation instruction):
PRINT @(34,12) : "Hello, world!"
Will display the string "Hello, world!" roughly centered in a 80X24 CRT.
Other functions:
PRINT @(-1) : @(34,12) : "Hello, world!"
Will clear the screen before displaying the string "Hello, world!" roughly centered in a 80X24 CRT.
Syntax variants:
CRT "Hello, world!"
Supporting the "@" functions above, the CRT statement ignores previous PRINTER statements and always sends output to the screen.
Some Pick operating system environments such as OpenQM support the DISPLAY variant of PRINT. This variant in addition to the "@" functions maintains pagination based upon the settings of the TERM variable:
DISPLAY "Hello, world!"

[edit] JavaFX
JavaFX is scripting language formerly called F3 for Form Follows Function
Frame {
title: "Hello World JavaFX"
width: 200
content: Label {
text: "Hello World"
}
visible: true
}
This program can also be written in this way:
var win = new Frame(); win.title = "Hello World JavaFX"; win.width = 200; var label = new Label(); label.text = "Hello World"; win.content = label; win.visible = true;
A simple console output version would be:
import java.lang.System;
System.out.println("Hello World");
Or even simpler (with a built-in function):
println("Hello World");
[edit] JavaScript
JavaScript does not have native (built in) input or output routines. Instead it relies on the facilities provided by its host environment.
Using a standard Web browser's document object
document.writeln('Hello, World!');
or with an alert, using a standard Web browser's window object (window.alert)
alert('Hello, world!');
or, from the Mozilla command line implementation
print('Hello, world!');
or, from the Windows Script Host
WScript.Echo('Hello, world!');

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!
[Exeunt]
