Hello world programs in Basic

From SytechPedia

General[edit]

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.

BlitzBasic[edit]

Print "Hello, world!"
WaitKey

DarkBASIC[edit]

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.

FreeBasic[edit]

PRINT "Hello World"
SLEEP
END

or

PRINT "Hello World"

or

? "Hello World"

or

'without a newline
? "Hello World";

CoolBasic[edit]

AddText "Hello, world!"
DrawScreen
WaitKey

GW-BASIC[edit]

10 PRINT "Hello, World!"
20 END

Liberty BASIC[edit]

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

Microsoft Small Basic[edit]

TextWindow.WriteLine("Hello, world!")

PBASIC[edit]

DEBUG "Hello, world!", CR

or, the typical microcontroller Hello, world! program equivalent with the only output device present being a light-emitting diode (LED) (in this case attached to the seventh output pin):

DO
     HIGH 7 'Make the 7th pin go high (turn the LED on)
     PAUSE 500 'Sleep for half a second
     LOW 7 ' Make the 7th pin go low (turn the LED off)
     PAUSE 500 'Sleep for half a second
 LOOP
 END

StarOffice/OpenOffice Basic[edit]

sub main
     print "Hello, world!"
 end sub

PureBasic[edit]

OpenConsole()
 PrintN("Hello, world!")
 Input()

or

MessageRequester("Hello, World","Hello, World")

or

Debug "Hello, World"

TI-BASIC[edit]

On TI calculators of the TI-80 through TI-86 range:

:Disp "Hello, world!          (note the optional ending quotes)
:Output(X,Y,"Hello, world!    (note the optional ending parenthesis)
:Text(X,Y,"Hello, world!      (writes to the graph rather than home screen)
:Text(-1,X,Y,"Hello, world!   (only on the 83+ and higher, provides larger text, home screen size)
:"Hello, world!               (last line of program only)

Note: "!" character is not on the keypad. It can be accessed from "Catalog" menu, "Probability" menu, or "Math" menu (as factorial notation).

On TI-89/TI-89 Titanium/TI-92(+)/Voyage 200 calculators:

:hellowld()
:Prgm
:Disp "Hello, world!"
:EndPrgm

Visual Basic[edit]

Public Sub Main()
    Debug.Print "Hello, world!"
End Sub

or

Public Sub Main()
  MsgBox "Hello, world!"
End Sub

or

Private Sub Form_Activate()
    Print "Hello, world!"
End Sub

Alternatively, copy this into a New Form:

Private Sub Form_Click()
   Form1.Hide
   Dim HelloWorld As New Form1
   HelloWorld.Width = 2500: HelloWorld.Height = 1000: HelloWorld.Caption = "Hello, world!": HelloWorld.CurrentX = 500: HelloWorld.CurrentY = 75
   HelloWorld.Show: HelloWorld.Font = "Tahoma": HelloWorld.FontBold = True: HelloWorld.FontSize = 12: HelloWorld.Print "Hello, world!"
End Sub

Visual Basic .NET[edit]

Module HelloWorldApp
  Sub Main()
     System.Console.WriteLine("Hello, world!")
  End Sub
End Module

PICK/BASIC, DATA/BASIC, MV/BASIC[edit]

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!"
