Jump to download section

R-BASIC Concepts: Overview

R-BASIC is a new programming language for PC/GEOS. It is easy to learn and easy to use, even for beginners. On the other hand, it is powerful enough for enhanced projects. R-BASIC requires a PC/GEOS version of GeoWorks 2.01 (or later). Recommended is one of the actual BreadBox Ensemble versions.

Why a BASIC?

  1. Simple synatx. R-BASIC combines the easy to learn BASIC syntax with a powefull command set to allow you to build professional projects.
  2. Compatibilty. There are lot of "old", but interesting programs, which are waiting to be ported to R-BASIC.
  3. You may refrer to almost every BASIC textbook to learn the basics about how to program with (R-)BASIC. Details may differ, but the concepts how to program are the same.

Is R-BASIC object oriented?

Yes, it is. You have access to the powerful PC/GEOS object system. See here for available object classes.
On the other hand, R-BASIC provides a "classic" mode which emulates an old-style home computer. This makes porting old programs easier and may be a good starting point for beginners.

How does R-BASIC work?

After writing your code, you have to "compile" the code. This step checks the syntax an creates a sequence of tokens, which can be "interpreted" by the executer. This is the same procedure as used by, for example, the java programming language. When compiling was ok, you may run the program or create an R-App. R-Apps are stand-alone programs which consists of the compiled code and a laucher which calls the executer. From users point of view, R-Apps look like "normal" programs, written with the PC/GEOS SDK.

The newest version of the R-BASIC program. For full installation, you have to download the following packages:
  1. IDE, Documentation, Examples, Images
    You should download all of these ZIP archives to install the newest version of R-BASIC. It contains the following four installer packages:
    • IDE
      This package contains the integrated BASIC development environment (IDE). That includes the editor, compiler, tools to create R-App's, help files, some tools and other essential files.
      Included tools, accessible from R-BASIC menu "Extras"-"Tools"

      Wizzard Editor

      Block Graphic Editor

      Font Explorer

      Basic Salvager
        View Screenshots

      Get More Tools

    • Examples
      There are a lot of examples that deals with the BASIC commands, the objects and special topics like working with files or block graphics. Click here for a list of all examples.
    • Documentation
      This package contains the R-BASIC manual and other documents. Small editorial changes may occur.
      • User Manual: Description of the R-BASIC IDE and other topics which are not part ot the R-BASIC language itself.
      • Progamming Manual: The BASIC Language.
      • Objects Manual: A complete description of the BASIC objects, its properties and abilities.
      • Special Topics: Additional themes such as fonts, files and block graphics.
      • R-BASIC Appendix: Addtional information, tables, error codes and much more.
      • Quick Reference Objects: List of all object classes, its instance variables, methods and the associated constants.
      • Object- and Command Overview (see also here)
      Special note: If you have installed older versions of R-BASIC you may have still some "German..." files stored in your R-BASIC\Documents folder. This files may be deleted savely. All information stored in these files are translated to English and included in the English manual.
    • Images
      R-BASIC comes with a selection of images for the tool bars, the document interface and so on. This package was released with R-BASIC 0.9.9. Its content is unchanged since version R-BASIC 0.9.1, because earlier it was a part of the IDE package.

  2. Recommended packages
    This are some important additional files, often required for programming with R-BASIC.
    The other libraries are used in special situations. You may download it only if a new version of an existing library is available or if a new library is available. Currently the following libraries are available:
    • DocumentTools - Version 1.1 - Released February 2020
    • VMFiles - Version 1.0.1 - Released July 2015
    • GeoRun - Version 1.0 - Released August 2021
    • ResourceFile - Version 1.0 - Released Januar 2022
    Programmers which have the PC/GEOS-SDK may download the SDK-Library-Kit. This kit allows you to expand R-BASIC by writing functions which are not planed by the original R-BASIC concept. You may find here all needed files and desciptions.

  3. Perhaps required
    If you have an older GEOS system (earlier than version 4.1) perhaps you need newer sound libraries (sound.geo and wav.geo) to make the R-BASIC sound commands work better. They will work with older libraries too, but the newer libraries will be better. Unfortunately both libraries are in use in the standard system configuration and therefore they cannot be replaced by the UniInstaller application automatically.
    Please check these libraries in your SYSTEM folder and replace it manually if they have a version number lower than 4.1. The archive contains both libraries in version 4.1. Don't forget to make a backup copy of your original libraries first.

Important news in the current version
  • The Swap command exchanges two variables of same type.
  • There are two new text object classes VisText and LargeText.
  • All text objects can save their text directly to a file and read it from there.
  • You may save project notes within your code file.

   Download Libraries

These libraries are used in special situations.



ResourceFile Libray
Version 1.0
(50 kB)

January 2022
Released with R-BASIC 1.0
The ResourceFile library gives you access to graphics and texts that are not stored in your program itself, but in a resource file.

To create a resource file you can use the program "Data ResourceMaker" (Download here, German only).

GeoRun Libray
Version 1.0
(58 kB)

August 2021
Released with R-BASIC 1.0
With the GeoRun library you can contact other GEOS programs from R-BASIC. You can start them, pass them files and close them. Furthermore, you can establish a connection between two R-BASIC programs so that they can communicate with each other. An example for the communication of two R-BASIC programs is included.
DocumentTools Libray
Version 1.1
(70 kB)

February 2020
Released shortly after R-BASIC 0.9.9.C
The DocumentTools library provides a lot of functions to help you working with documents. One example are the typically dialog boxes to open a file or to save it with a new name. The routines of the DocumentTools library works closely together with the DocumentGuardian object. Using the routines from the DocumentTools library makes it very easy to implement a document interface, which provides the common functionality. This is explained in detail in the "Special Topics" manual, volume 3, chapter 15.
The whole document interface code can be included into your program from a R-BASIC menu ("Extras", "Code Sequences", "Document Interface"). In this case, the DocumentTools library is required because it is used by the code, inserted from this menu.
VMFiles Libray
Version 1.0.1
(109 kB)

July 2015
Released with R-BASIC 0.9.2
The VMFiles library allows R-BASIC the access to the powerful GEOS VM files. The documents of all "big" GEOS applications, like GeoDraw, GeoWrite, and R-BASIC itself are VM files.
VM files are versatile and simple to use. An example - you want to develop your own movie database program. In this case you should use VM files. You don't need to know how many movies finally will be stored in the database before you start developing. A single command allows you to add or remove a movie title. If you like to add a movie cover image to your database, you can do this with some few commands. VM files are designed to store images, too.
The VMFiles library is required for working with VM files.

SDK Library Kit (28 kB)

Version 1.0.1
August 2017
Released with R-BASIC 0.9.8
This package conatins all necessary files and information to write libraries for R-BASIC with the PC/GEOS SDK. This allows you to add features to R-BASIC, which are usually not supported. For example, the VMFiles library and DocumentTools library are written with this kit.
This kit is complete in English. It contains detailed descriptions and examples for typical situations.
Version 1.0.1 adds a few handle and "register" types about sound issues to the sdklib.goh file. You may update your version 1.0 to 1.0.1 only if you wish to deal with R-BASIC sounds in your library.

Token PCX Tool (8,9 kB)

March 2013

ICONMAKE is a DOS program by Marcus Groeber, that converts PCX or ICO file to "Token-Dummies". That are mini GEOS programs that install its token to the token database file.

The Icon Editor is a GEOS appliaction that allows to draw icons for GEOS. It's a little painting program that supports read and write tokens from and to the token database. It also supports writing the tokens as source code for the SDK and much more.
The current version 3.1 can draw 256 color icons, but the import from and export to token database is still broken. Writing source code is fixed already.

Token PCX Tool is a small tool from SDK that can read 8 bit per pixel PCX files and create an icon in the token database file from that pcx file. The pcx file must have the icon images at mandatory positions. Details are explained in the readme.txt file. A demo pcx file is also included.

Available Object Classes


The Application object is invisible.

This object connects your program to the GEOS system. It is the top parent for all other generic objects in your program. Every BASIC program must have exactly one Application object. Usually, the direct child of the Application is a Primary object.

Objects of class Primary are the main windows of your program. They have a system menu in the left upper corner, a minimize button a maximize button and a help button in the right upper corner. Usually, R-BASIC programs have exactly one Primary object.


A button is an active area that can be activated by mouse or by keyboard. Buttons are used for menu items or as single objects.

Groups are designed to organize its children in the way that you as programmer wish. The application on the left consists of a group (red, above) and a reply bar (which really is a group too) below. The red framed group contains a text object on the left side and a (blue framed) group that contains some action buttons.

Menus are the common way for the user to access different parts of the program functionality. Menu items are the children of a menu object. Very often, these are buttons. You may create nested menus by having a menu object to be a child of another menu object, as shown in the image on the left side. You may also use dialogs to be a menu's child. The system will create a button as menu item for you, that open the dialog. Any other objects, for example groups or list objects, are allowed for menu items, too.

Dialogs are independently-displayable interface elements used to display information or other UI objects. They are used for different purposes. Therefore, a Dialog object has a lot of features that makes dialog easy to use. On the other hand, dialogs may be configured to do advanced things.

Objects of Number class allow to display or to enter a number. They are simple to use and very versatile. For example, you may configure the numer of decimal places as well as the minimum and the maximum value to display. Number objects may be configured to appear as sliders.

OptionGroup with 3 Option objects

The OptionGroup manages a list of Option objects. Every Option object may have the state "on" or "off".
RadioButtonGroup with 3 RadioButton objects

The RadioButtonGroup manages a list of RadioButton objects that may be selected individually or in groups. The RadioButtonGroup is a very versatile object. It is often used when the number of list items is known and does not change while the program is running.

The DynamicList is a subclass of the RadioButtonGroup and therefore it inherits all its capabilities. A DynamicList is often used when the number of list items is initially unknown or may change while the program is running.
with a

The View object class provides a "window" to graphic data (this includes text) you wish to display. The data to be drawn are provided by the views "content" object. This content object just has to know how to draw the data, that's all. The view, on the other side, handles scrolling (if necessary), scaling and clipping. It requests its content do draw itself, but the view decides which part of that drawing will appear on the screen. This is a very powerful concept.
Objects of class BitmapContent are "content" objects of a View object. They manage an editable bitmap. The object automatically creates its bitmap. You may write (draw) text or graphics to the bitmap of the BitmapContent object.

BitmapContent Objects may react on keyboard and mouse events by calling the aproriate handlers. It also may work with the Clipboard.

with some VisObj objects

Objects of the VisContent class are used to output graphics in a scalable and scrollable View. They can also respond to keyboard and mouse input.

The VisContent object either provides the graphics itself, or it uses children (of the VisObj class), which in turn can output graphics and respond to keyboard and mouse.
The arrangement of VisObj objects can be done conveniently automatic or manual with full control.

The picture on the left shows a VisContent that displays a background graphic on which the VisObj objects are drawn.

Objects of the VisObj class display user-defined graphics as children of a VisContent. They can interact with the mouse and keyboard. Furthermore, they can have children (further VisObj objects) themselves.
R-BASIC supports the positioning of VisObj objects with the mouse (dragging) very comfortably.

Objects of GenContent class are used to show generic class objects like buttons in a scrollable View. For example the "Preferences" application uses this mechanism.

GenContent objects may have any kind of generic class objects as its children. In the image on the left side this are three Buttons, a RadioButtonGroup and a Canvas object.


The ViewControl object class provides the UI for the "View" menu. This UI basically controls the scale factor and some other features of controlled View objects.
When the View is configured to work with a ViewControl object all interaction between View and ViewControl takes place automatically.

Canvas objects display a graphic by calling its OnDraw handler. They also may work in a very fast mode, called bufferd mode. Canvas objects may react on mouse events. You have to write mouse handlers for this purpose. Additionally, Canvas objects may work with the clipboard.

An Image object displays a graphic which is stored in a graphics file or in the PictureList. You have nothing to do but to specify the graphic to display. The object may also play animations from a file. You may specify if the animation will run automatically or on request.

Supported graphic formats:
  • Graphic files: JPG, BMP, ICO, PCX, GIF, TGA, RLE, DIB, SCR (BreadBox SplashScreen)
  • VM files: GEOS Background files, Resource-Maker files (Bitmaps and GStrings)
  • Animations: GIF, FLC, FLI, BreadBox QuickCam Format




The R-BASIC text objects allow simple text input, without requiring extensive support in your application. Text objects handle keyboard and mouse events automatically and will create scroll bars if they are needed. They know if the text is modified by the user and may send out messages for different events.
All Text objects can work with the clipboard.

In R-BASIC there are four text object classes available.

  • The class Memo provides a simple text editor object. It allows word wrapping and multiple paragraphs, created when the user hits the enter key.
  • The second class, InputLine class, is designed to accept the input of single line texts, like file names.
  • Objects of the VisText class must be used like a VisObj object in a visual tree.
  • The advantage of the LargeText objects is that they can store any amount of text (theoretically up to 2 GByte), while the other text objects are limited to 4 kByte.

A file selector provides a user interface, which is recommended to select a file or a directory. The file selector sends a notification message as soon as a user clicks to an entry, so the programmer can manage the further steps. In the most cases the selected file will just be opened. The navigation to drives and sub directories handles the FileSelector by itself.

Which file will be shown in the list can be controlled for example by the file token or by a file mask.


A ColorSelector provides the UI needed to select a color, a shaded value or a fill pattern.

The programmer can select which of these features are displayed to the user. By default, only the index colors are available, as shown in the picture on the left.

Display and DisplayGroup

Object of the class Display are the "windows" in which all big applications like GeoWrite or R-BASIC display its data. For this reason, Display objects contain other UI objects to display the content. In the image to the left this is a Memo object. Display objects have to be children of a DisplayGroup object.

A DisplayGroup provides the visible area for the Display objects. The image on the lefts side contains three Display in a DisplayGroup.

The DisplayControl provides the UI to allow the user to interact with the DisplayGroup object. It also contains al list of all available Displays. As shown in the image on the left, a DisplayControl is usually a child of the "Window" menu.

The DocumentGuardian object is invisible.

A lot of programs work with documents. Objects of class DocumentGuardian help the programmer to manage documents. They store important common information about a document such as the file name, the path, the file type, the token and the FILE handle of the open document file.

DocumentGuardian objects works closely together with the library "DocumentTools". For example, this library provides some dialog boxes such as "Open" and "Save as".

DocumentGuardian objects can also work with the "VMFiles" library. This library allows access to the powerfull "virtual memory" (VM) files, which are used as documents by all big GEOS applications.


Th PrintControl object itself is invisible. It provides the "Print" dialog box.

PrintControl: the "Print" dilaog box

If you wish to print from a R-BASIC program, you have to include a PrintControl object. The PrintControl object provides the "Print" dialog box and manages all tasks, required for printing.

When the user should be allowed to select or change the size of a document, you should include a PageSizeControl object. This object provides all UI, required to select or change the page size, the paper format or the margins.


News in the current version

Important News:
  • New features
    • The dialog boxes for Find and Replace have been separated. The F4 or Shift-F4 keys can be used to jump to the next or previous search result, even if the corresponding dialog box is already closed.
    • Advanced compiler options allow finding declared but unused identifiers such as variables.
    • The Swap command exchanges two variables of same type.
    • There are two new text object classes VisText and LargeText. VisText objects allow editing of text directly on the graphics screen, LargeText objects allow you to display and edit very large amounts of text.
    • All text objects can save their text directly to a file (DOS file, GEOS data file or VM file) and read it from there. If necessary, the text can be converted between different character sets at the same time.
    • All text objects have the methods Suspend and EndSuspend. This allows multiple changes to the object without flickering.
    • The command POS has been renamed to CsrPos. Therefore, the identifier pos is availabe for variable names now.
    • The new methods HideDelayed and ShowDelayed are available for all generic class objects.
    • You can save project notes in your code file. There are 4 text fields (e.g. a to-do list, a bug list, etc.) available and the notes are saved automatically.
    • New object classes VisContent and VisObj for convenient and flexible graphic output. VisObj objects can be positioned automatically (by rows or columns, with wrapping if required), manually (by program statement) or with the mouse (dragging).
    • There is a new standard path constant SP_PRIV_DATA to enter the PRIVDATA folder.
    • The code wizard was made more clearly structured
    • Extended syntax highlighting.The compiler adds globally defined identifiers (global variables, routine names ...) to the list of words, which are highlighted by the editor. Note that this list is not stored in the document and is updated with every compiler run.
    • Full-text search in the manuals is supported (see Help menu).
    • The syntax color files are updated. There is a new color scheme (Bernstein IBM).
    • When creating an R-App, the installer package takes the user notes from the launcher.
    • Search and Replace (Ctrl-F) and Search in files (Ctrl-D) copy the text at the cursor automatically into the search dialog box. In addition, the search history will be recorded.
    • The ESC key now also closes the Search and Replace, Search in Files and Search Results dialogs.
    • The key commands Ctrl-M (mark block as comment), Ctrl-N (undo Ctrl-M) Ctrl U (shift block left) Ctrl I (shift block right) now also work for the current line, without anything having to be marked.
    • Bookmarks may be set in the source code (F6-Key). Quick jump to bookmarks is possible with Strg-E and Shift-Strg-E.
    • New editor functions added:
      • Find corresponding bracket (Ctrl-O).
      • Capitalize the selected text (Shift Ctrl-U).
      • Lowercase the selected text (Shift Ctrl-D).
      • Invert selected text capitals and lower case (Shift Ctrl-K).
      • Format selected text according to syntax highlighting (Shift Ctrl-M).
    • In the toolbar there are tools for Search/Replace, Undo/Redo and for the Bookmarks.
    • The options menu has been restructured. Here you can also find new functions:
      • Show/hide the message window under the code text (Ctrl-T).
      • Switch on/off all tools in the toolbar (state will be saved to GEOS.INI file)
      • Temporary switching on/off of the toolbar (Shift-Ctrl-T, without saving in the INI file)
      • Switch off the additional message box for compiler warnings
    • A clean copy of the source code file may be created (File menu) to cleanup lost handles, unused space and so on.
    • The edit commands Ctrl-V etc. now also work with the input texts in dialog boxes, e.g., in Find/Replace and when creating new objects or UI sequences.
    • When printing BASIC code, the code window name is printed in the header.
  • Internal changes
    • The compiler output is no longer written to the code file itself, but to an external file. This keeps the code file smaller.
    • If you specify additional files for the installer package in the "Create R-App" dialog, then these are now marked as "Do not remove when uninstalling". This prevents the user from accidentally removing files (for example fonts) while uninstalling.
    • Bug in the undo chain fixed.
    • Several other bugfixes and improvement of the stability.
    • DATA lines store numeric values as 2 or 4 bytes (instead of 10), if possible.
    • The ON..SWITCH instruction has been optimized significantly. In addition, a compiler error occurs if a value is used more than once in a CASE statement.
    • The printing of BlockGraphic characters could be accelerated for the frequent case "no transparent background".
