All Programming Languages-Hello World! 1

List of hello world programs

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

The ALGOL 68 standard requires that reserved-words, types and operators are in a different typeface. Hence programs are typically published in either bold or an underline typeface, eg:

begin     printf($"Hello, world!"l$) end 

In the popular upper-case stropping convention for bold words:

BEGIN     printf($"Hello, world!"l$) END 

or using a wikitext like quote stropping, this is especially suitable on computers with only 6 bits per character (hence only have UPPERCASE):

'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> 

or

<asp:Label ID="Label1" runat="server" Text="Hello World">asp:Label>

[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]Visual Basic

[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!');

[edit]MS-DOS batch

(with the standard command.com interpreter. The @ symbol is optional and prevents the system from repeating the command before executing it. The @ symbol must be omitted on versions of MS-DOS prior to 3.0.). It's very common for batchfiles to start with two lines of "@echo off" and "cls".

 @echo Hello, world! 

For MS-DOS 3.0 or lower

however, in bigger applications the following code would be probably more useful:

[edit]Oberon

Oberon is both the name of a programming language and an operating system.

Program written for the Oberon operating system:

MODULE Hello;         IMPORT Oberon, Texts;  VAR W: Texts.Writer;   PROCEDURE World*;  BEGIN    Texts.WriteString(W, "Hello, world!");    Texts.WriteLn(W);    Texts.Append(Oberon.Log, W.buf)  END World;  BEGIN  Texts.OpenWriter(W) END Hello. 

Freestanding Oberon program using the standard Oakwood library:

MODULE Hello;    IMPORT Out; BEGIN    Out.String("Hello, world!");    Out.Ln END Hello.
