Commodore BASIC
Commodore 64
There are no text drawing routines in BASIC that apply to the high resolution bitmap mode on the Commodore 64. Therefore, it is necessary to either draw letterforms from designs stored in RAM, or copy the font contained in ROM. It should be noted that using BASIC to handle high resolution graphics is a slow process, and the same tasks are much more efficiently accomplished in assembly language/machine code.
This example will iterate through the string and copy the appropriate bitmap information from the Character ROM. In line 425 a conversion must take place since strings are stored in memory as bytes of ASCII (PETSCII) codes, however, the Character ROM is stored in order of the screen codes as found in Appendix B of the Commodore 64 Programmer's Reference Guide... And even then the conversion given will work only for a limited set of the Character ROM. This could be remedied if the Character ROM (or some other font definition) was copied to RAM and indexed in ASCII/PETSCII order.
The POKE statements encapsulating the text drawing routine (lines 410-415 and 450-455) are necessary to make the Character ROM visible to BASIC without crashing the operating system. As such, keyboard scanning must be suspended during this time, preventing the routine from any user interruption until it is finished.

Common Lisp
This can be done using the extension package ltk that provides an interface to the Tk library.
<lang lisp>(use-package :ltk)
(defun show-message (text)
"Show message in a label on a Tk window"
(with-ltk ()
(let* ((label (make-instance 'label :text text))
(button (make-instance 'button :text "Done"
:command (lambda ()
(ltk::break-mainloop)
(ltk::update)))))
(pack label :side :top :expand t :fill :both)
(pack button :side :right)
(mainloop))))
(show-message "Goodbye World")</lang>
This can also be done using the CLIM 2.0 specification. The following code runs on both SBCL and the LispWorks IDE:
<lang lisp> (in-package :clim-user)
(defclass hello-world-pane
(clim-stream-pane) ())
(define-application-frame hello-world ()
((greeting :initform "Goodbye World"
:accessor greeting))
(:pane (make-pane 'hello-world-pane)))
- Behaviour defined by the Handle Repaint Protocol
(defmethod handle-repaint ((pane hello-world-pane) region)
(let ((w (bounding-rectangle-width pane))
(h (bounding-rectangle-height pane)))
;; Blank the pane out
(draw-rectangle* pane 0 0 w h
:filled t
:ink (pane-background pane))
;; Draw greeting in center of pane
(draw-text* pane
(greeting *application-frame*)
(floor w 2) (floor h 2)
:align-x :center
:align-y :center)))

(make-application-frame 'hello-world :width 200 :height 200))</lang>

Dart
Flutter
Because Flutter works on the Web in addition to Mobiles and Desktop, you can view these examples on Dartpad! - https://dartpad.github.io
Simplest (and ugliest) solution <lang javascript>import 'package:flutter/material.dart';
main() => runApp( MaterialApp( home: Text( "Goodbye, World!" ) ) ); </lang>
A still bare bones but much better looking example that displays a white screen with the text centered <lang javascript>import 'package:flutter/material.dart';
void main() {
runApp(
MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold (
body: Center (
child: Text( "Goodbye, World!")
)
)
)
);
} </lang>
Html dom manipulation, Dart has first class support for compilation to JavaScript. This simply sets the innerHtml of the body to 'Goodbye, World!'
Web/Javascript
<lang javascript>import 'dart:html';
main() => document.body.innerHtml = '
Goodbye, World!
';
</lang>
<lang javascript>import 'dart:html';
main() => window.alert("Goodbye, World!"); </lang>

Here are solutions for Microsoft Windows, using the MessageBox API function. Both programs use modules provided by the compiler vendor.
<lang fortran>program hello
use windows
integer :: res
res = MessageBoxA(0, LOC("Hello, World"), LOC("Window Title"), MB_OK)
end program</lang>
Compile with af90 hello.f90 user32.lib or for a 64-bit executable af90 -i8 -m64 hello.f90 user32.lib.
<lang fortran>program hello
use user32 integer :: res res = MessageBox(0, "Hello, World", "Window Title", MB_OK)
end program</lang>
Compile with ifort hello.f90.

Fennel
<lang Fennel> (fn love.load []

(love.window.setTitle "Hello world/Graphical in Fennel!"))
(let [str "Goodbye, World!"]

</lang>
To run this, you need to have LÖVE installed in your machine, and then run this command fennel --compile love_test.fnl > main.lua; love .. Since LÖVE has no compatibility with Fennel, we need to AOT-compile the file to a Lua file called main.lua, so then LÖVE can execute the program.

Frink
This brings up an infinitely-rescalable graphic window containing "Goodbye, World" drawn graphically.
All Frink graphics can be written to arbitrary coordinates; Frink will automatically scale and center any drawn graphics to be visible in the window (greatly simplifying programming,) so the exact coordinates used below are rather arbitrary. (This means that if you wrote "Hello World" instead of "Goodbye, World", you could just change that string and everything would still center perfectly.)
The graphics are infinitely-scalable and can be rendered at full quality to any resolution. This program "shows off" by rotating the text by 10 degrees, and also rendering it to a printer (which can include tiling across multiple pages) and rendering to a graphics file. (Frink can automatically render the same graphics object to many image formats, including PNG, JPG, SVG, HTML5 canvas, animated GIF, bitmapped image in memory, and more.)
<lang frink> g = new graphics g.font["SansSerif", 10] g.text["Goodbye, World!", 0, 0, 10 degrees] g.show[]

jq
In the following, which generates SVG in a way that can be readily viewed using a web browser, the "Goodbye, World!" text is shaded using a linear gradient.
The approach used here to generate SVG is based on these principles:
- a JSON object is used to specify CSS styles
- this makes it easy to combine default specifications with partial specifications, because in jq, for JSON objects, "+" is defined so that (default + partial) is the combination which gives precedence to the right-hand-side operand;
- for other defaults, the jq "//" operator can be used; thus all SVG parameters can be easily given defaults.
Part 1: Generic SVG-related functions <lang jq># Convert a JSON object to a string suitable for use as a CSS style value
- e.g: "font-size: 40px; text-align: center;" (without the quotation marks)
def to_s:
reduce to_entries[] as $pair (""; . + "\($pair.key): \($pair.value); ");
- Defaults: 100%, 100%
def svg(width; height):
"<svg width='\(width // "100%")' height='\(height // "100%")'
xmlns='http://www.w3.org/2000/svg'>";
- Defaults:
- id: "linearGradient"
- color1: rgb(0,0,0)
- color2: rgb(255,255,255)
def linearGradient(id; color1; color2):
"<defs>
<linearGradient id='\(id//"linearGradient")' x1='0%' y1='0%' x2='100%' y2='0%'>
<stop offset='0%' style='stop-color:\(color1//"rgb(0,0,0)");stop-opacity:1' />
<stop offset='100%' style='stop-color:\(color2//"rgb(255,255,255)");stop-opacity:1' />
</linearGradient>
</defs>";
- input: the text string
- "style" should be a JSON object (see for example the default ($dstyle));
- the style actually used is (default + style), i.e. whatever is specified in "style" wins.
- Defaults:
- x: 0
- y: 0
def text(x; y; style):
. as $in
| {"font-size": "40px", "text-align": "center", "text-anchor": "left", "fill": "black"} as $dstyle
| (($dstyle + style) | to_s) as $style
| "<text x='\(x//0)' y='\(y//0)' style='\($style)'>
\(.)",
"</text>";</lang>
Part 2: "Goodbye, World!" <lang jq>def task:
svg(null;null), # use the defaults
linearGradient("gradient"; "rgb(255,255,0)"; "rgb(255,0,0)"), # define "gradient"
("Goodbye, World!" | text(10; 50; {"fill": "url(#gradient)"})), # notice how the default for "fill" is overridden
"</svg>";
task</lang>
- Output:
jq -n -r -f Hello_word_Graphical.jq > Hello_word_Graphical.svg

Jsish
Using JSI CData processing, C, and linking to libAgar.
- Output:

# require('JsiAgarGUI')
1
# JsiAgarGUI.alert("Goodbye, World!");
#
Window pops up with message and Ok button.
That is based on JSI CData, a blend of typed Javascript and C, interwoven via a preprocessor.
<lang c>extension JsiAgarGUI = { // libAgar GUI from Jsi
/*
Alert popup, via libAgar and Jsish CData
tectonics:
jsish -c JsiAgar.jsc
gcc `jsish -c -cflags true JsiAgar.so` `agar-config --cflags --libs`
jsish -e 'require("JsiAgar"); JsiAgar.alert("Goodbye, World!");'
*/
#include <agar/core.h>
#include <agar/gui.h>
/* Terminate on close */
void windDown(AG_Event *event) {
AG_Terminate(0);
}
function alert(msg:string):void { // Display a JsiAgar windowed message
/* Native C code block (in a JSI function wrapper) */
AG_Window *win;
AG_Box *box;
Jsi_RC rc = JSI_OK;
if (AG_InitCore(NULL, 0) == -1 || AG_InitGraphics(0) == -1) return (JSI_ERROR);
AG_BindStdGlobalKeys();
win = AG_WindowNew(0);
box = AG_BoxNew(win, AG_BOX_VERT, 0);
AG_LabelNewS(box, AG_LABEL_HFILL, msg);
AG_ButtonNewFn(box, AG_BUTTON_HFILL, "Ok", AGWINDETACH(win), "%p", win);
AG_SetEvent(win, "window-detached", windDown, NULL);
AG_WindowShow(win);
AG_EventLoop();
AG_DestroyGraphics();
AG_Destroy();
return rc; }
};</lang>
Build rules are jsish -c preprocessor, query jsish for C compile time flags, compile the C, load the module into jsish via require.
prompt$ make -B -f Makefile.jsc hello
jsish -c JsiAgarGUI.jsc
gcc `jsish -c -cflags true JsiAgarGUI.so` `agar-config --cflags --libs`
jsish -e 'require("JsiAgarGUI"); JsiAgarGUI.alert(" Goodbye, World! ");'
And a window pops up with the message and an Ok button.
First command jsish -c runs a JSI to C preprocessor, generating a .h C source file.
For the second step, gcc is called with the output of a jsish -c -cflags true query, libagar runtime is linked in with more substitution for Agar compiler commands. The query output will be something like (this is site local, details will change per machine setup):
prompt$ jsish -c -cflags true JsiAgarGUI.so -g -Og -O0 -Wall -fPIC -DJSI__SQLITE=1 -DJSI__READLINE=1 -fno-diagnostics-show-caret -Wc++-compat -Wwrite-strings -DCDATA_MAIN=1 -x c -rdynamic -I/home/btiffin/forge/jsi/jsish/src -DJSI__WEBSOCKET=1 -I/home/btiffin/forge/jsi/jsish/websocket/src/lib -I/home/btiffin/forge/jsi/jsish/websocket/src/build -I/home/btiffin/forge/jsi/jsish/websocket/unix -I/home/btiffin/forge/jsi/jsish/websocket/build/unix -o JsiAgarGUI.so JsiAgarGUI.h -lm -shared -DCDATA_SHARED=1 -L /home/btiffin/forge/jsi/jsish/websocket/build/unix/ -lwebsockets -I/home/btiffin/forge/jsi/jsish/sqlite/src -L /home/btiffin/forge/jsi/jsish/sqlite/build/unix/ -lsqlite3 -lm -ldl -lpthread prompt$ agar-config --cflags --libs -I/usr/local/include/agar -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/libpng16 -L/usr/local/lib -lag_gui -lag_core -lSDL -lpthread -lfreetype -lfontconfig -lfreetype -L/usr/local/lib -lGL -lX11 -lXinerama -lm -L/usr/lib -ljpeg -L/usr/lib64 -lpng16 -ldl

N/t/roff
Whether the output is graphical or text depends largely the compiler with which the /.ROFF/ source code below is compiled. If it is compiled with an Nroff compiler, its output is comparable to that of a typewriter. Therefore, output from Nroff is typically seen on a text terminal. If it is compiled with a Troff compiler, its output is comparable to that of a typesetter. Therefore, output from Troff is typically seen on a PostScript or PDF output using a document viewer. Furthermore, output from Troff is also usually seen on paper, so that may count as graphical as well. In conclusion, although the code is compatible with both Nroff and Troff, it should be compiled using Troff to guarantee graphical output.
Because /.ROFF/ is a document formatting language in and of itself, it is extremely likely that a user of /.ROFF/ will be typing mostly textual content in a natural language. Therefore, there are no special routines or procedures to be called to output normal text, as all text will get formatted onto paper automatically.

PostScript
In the general Postscript context, the show command will render the string that is topmost on the stack at the currentpoint in the previously setfont. Thus a minimal PostScript file that will print on a PostScript printer or previewer might look like this:
<lang postscript>%!PS % render in Helvetica, 12pt: /Helvetica findfont 12 scalefont setfont % somewhere in the lower left-hand corner: 50 dup moveto % render text (Goodbye, World!) show % wrap up page display: showpage</lang>

new(T, text(S)),
get(@display, label_font, F),
get(F, width(S), M),

- While there is no easy (intuitive) way to print a comma (or semicolon) this pd script will do.
- When writing messages to the terminal window, Pd prepends the name of the print object and a colon, or "print: " if no name is specified, which can be avoided by using "-n" instead of a name. This behaviour, however, has not been adopted by Pd-extended :-(

Scratch
ScratchScript
<lang ScratchScript>pos -100 70 print "Goodbye, World!"</lang> This example waits until the mouse is clicked for the program to end. This can be useful if the program executes too fast for "Hello world!" to be visible on the screen long enough for it to be comfortable. <lang ScratchScript>pos -100 70 print "Goodbye, World!" delayOnClick</lang>
Seed7
Seed7 does not work with an event handling function like gtk_main(). The progam stays in control and does not depend on callbacks. The graphic library manages redraw, keyboard and mouse events. The contents of a window are automatically restored when it is uncovered. It is possible to copy areas from a window even when the area is currently covered or off screen.

But it isn't completely cheating: the SSEM uses Williams tube storage, so the memory is basically a CRT device; and this is an executable program, up to a point, because the first line includes a 111 Stop instruction (disguised as a little flourish joining the tops of the d and the b). <lang ssem>01100000000001110000000000000000 10000000000001010000000000000000 10011101110111011101010111000000 10010101010101010101010101000000 10010101010101010101010111000000 10011101110111011100110100000010 10000000000000000000010011000010 10011000000000000000100000000100 01101000000000000001000000000000 00000000000000000000000000000000 00000000000000000000000000000000 00100100100000000010000100100000 00100100100000000010000100100000 00100100101110111010011100100000 00100100101010100010010100100000 00100100101010100010010100000000 00100100101110100011011100100000 00011011000000000000000000000000</lang> Once you've keyed it in, the first eighteen words of storage will look a bit like this:
oo ooo o o o o ooo ooo ooo ooo o o ooo o o o o o o o o o o o o o o o o o o o o o o o o ooo o ooo ooo ooo ooo oo o o o o oo o o oo o o oo o o o o o o o o o o o o o o o o o ooo ooo o ooo o o o o o o o o o o o o o o o o o o o o o o o ooo o oo ooo o oo oo

Tcl
Just output as a label in a window: <lang tcl>pack [label .l -text "Goodbye, World"]</lang>
Output as text on a button that exits the current application:
<lang tcl>pack [button .b -text "Goodbye, World" -command exit]</lang>
Note: If you name this program "button.tcl", you might get strange errors.
Don't use the name of any internal tcl/tk-command as a filename for a tcl-script.
This shows our text in a message box: <lang tcl>tk_messageBox -message "Goodbye, World"</lang>

This example used the Windows MessageBox function to do the work for us. Windows uses the stdcall calling convention where the caller pushes function parameters onto the stack and the stack has been fixed up when the callee returns. <lang assembly>;;; hellowin.asm

XSLT
The output is an SVG document. The idea is that it's straightforward to use XSLT to turn an existing SVG into an instantiable template.
<lang xml><xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="xml"/> <xsl:template match="/*"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 400 200"> <rect x="0" y="0" width="400" height="200" fill="cyan"/> <circle cx="200" cy="100" r="50" fill="yellow"/> <text x="200" y="115" style="font-size: 40px; text-align: center; text-anchor: middle; fill: black;"> <xsl:value-of select="."/> </text> </svg> </xsl:template> </xsl:stylesheet></lang>
Sample input:
<lang xml><message>Goodbye, World!</message></lang>
Sample output (with formatting non-destructively adjusted):
<lang xml><svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 400 200"> <rect x="0" y="0" width="400" height="200" fill="cyan"/> <circle cx="200" cy="100" r="50" fill="yellow"/> <text x="200" y="115" style="font-size: 40px; text-align: center; text-anchor: middle; fill: black;">Goodbye, World!</text> </svg></lang>
