If you run GW-BASIC in a DOS box under Windows XP and GW-BASIC is not displayed correctly, type the following at the DOS prompt: MODE CON COLS=80 LINES=25
at the DOS prompt type: ECHO statements GWBASIC and GW-BASIC executes the statements and returns to DOS. For more information about Redirection and Piping in MS-DOS / PC-DOS download DOS_PIPE from Jan van Hulten.

GW-BASIC is a version of BASIC that was supplied with MS-DOS and as a replacement for IBM ROM basic. GW-BASIC replaced the earlier BASIC-86 supplied with some non-IBM OEM MS-DOS 1.x and 2.x. MS-DOS 5.0 and later replaced GW-BASIC with QBasic , a stripped down version of QuickBasic.
PC-BASIC is an interpreter for GW-BASIC files. It runs on Windows, Mac and Linux and other Unix-based systems and targets full compatibility with GW-BASIC version 3.23. PC-BASIC can run (and convert between) ASCII, bytecode and 'protected' (encrypted) .BAS files. It implements floating-point arithmetic in the Microsoft Binary Format (MBF) and can therefore read and write binary data files created by GW-BASIC.PC-BASIC is free and open source software released under the GPL version 3.

This document lists brief descriptions of current and older MS-BASIC development tools for the PC, along with a brief list of features and notes. While you may find older versions of development tools in many places, links to the old/used programming tools sales pages of EMS Professional Software, this page's sponsor, are provided for your convenience. Other Microsoft version information. Information on other vendors' products. For technical questions, we recommend you ask on news:comp.lang.basic.misc All terms on this page are trademarks of Microsoft Corporation. Microsoft's licensing spokesperson "Rich H." told me, on 2-8-00, that anyone with a valid license to use any recent version of Visual Basic is also licensed to use any older version of Microsoft Basic products. I haven't heard this before, so you should confirm this for yourself. Previously, Microsoft representatives had stated that you could downgrade only two version levels.
GW-Basic 3.23 - 1988 Microsoft Corporation. GW-BASIC was Microsoft's second incarnation of their BASIC programming language interpreter. As an interpreter it could only read, edit, and run BASIC source code. It could not compile BASIC programs into standalone programs. This version was released with MS-DOS. Total installed size: 78.7K
In 1991 DOS was still King for personal computer use. Microsoft released MS-DOS 5.0. For years Microsoft had received criticism for the clunky text editor EDLIN, which had been essentially unchanged for years. They also wanted to update their old GWBASIC interpreter which had not been improved for years. Microsoft took the QuickBasic IDE, stripped out the compiler, de-tuned the threaded p-code interpreter so it was slower than QuickBasic's QB.EXE (I suspect that QBasic may be based on the QuickBasic 4.0 QB.EXE rather than 4.5), added the '/EDITOR' command line option so QBasic could double as a screen-based text editor, and released the result as QBasic 1.0 with MS-DOS 5.0. For easy user interface, Microsoft created a tiny program EDIT.COM which executed QBasic with the /EDITOR option, and passed it's own command line tail. The combo replaced GWBASIC and EDLIN with much improved products. When MS-DOS 6.0 was released in 1993, QBasic version 1.1 came with it, and with all 6.x versions of MS-DOS. QBasic 1.1 (QBASIC.EXE and QBASIC.HLP) also came with Windows 95 (look on the CD in \other\oldmsdos\) and Windows 98 (look on the CD in \tools\oldmsdos\). You can also download the contents of the \oldmsdos\ subdirectory from
During its marketing life, there were quite a number of successive versions of GW-BASIC. Some, especially in the beginning tended to be vendor-specific. The LOCATE command could not address line 25 on machines that had 24-line monitors, for example. Likewise, those unfamiliar with the multiple alphabets of Kanji have probably never seen those specialized versions of GW-BASIC that could cope with 2-byte-wide character codes. Beyond that, like most all commercial software, successive versions came along for two reasons: 1) To add features needed to keep pace with newer hardware technology, and 2) To fix bugs in previous releases. Thankfully, in a way, the bug fixing ceased with Version 3.23 which is the last, most recent, most modern, most complete GWBASIC.EXE product obtainable.
GWBASIC.EXE is copyrighted software. The copyright is owned by Microsoft Corp. When sold as a component program of MS-DOS, only Microsoft's copyright notice is shown on the GW-BASIC start-up screen. When licensed to other vendors by Microsoft, their own copyright notice may also be visible on the start-up screen. Regardless, the interpreter is a copyrighted product and in my opinion, it is not legal to sell or give copies of it away. Even if I am wrong--a distinct possibility--I do not wish to be accused of abetting the Cyber Mafia or anybody else. Go find your own copy of GWBASIC.EXE. Google knows how to do it, by the way. A number of programming forum sites will point you to a free download source as well.
GW-BASIC 3.23 uses a queue-based algorithm which is pretty robust. It has no trouble with either of your test cases or the u's mentioned by scruss; however it's still possible to design a pattern specifically to make it use lots of memory and overflow, even though it has nearly 60K available:
(Note there's a GW-BASIC emulator called PC-BASIC; however, as of this writing, the flood fill algorithm it uses is not the same queue-based algorithm implemented in GW-BASIC 3.23, besides the fact that it "cheats" by having much more memory available).
I downloaded the PDF I mentioned earlier - painfully slow and the text is hard to select and when you do grab some the OCR is full of errors.So, I typed in the 6502 assembly routine for the 4-way flood fill.
eran tiempos dificiles donde fue dificil cambiar del basic de commodore,(yame estaba olvidando de mi querida commodore 64),al del gwbasic,tipeando ytipeando,traducir para que funque en las xt,sin manuales,sin libros oinaccesibles,el gwbasic fue nuestro aliado.aprendi a leer sus lineas en lasrevistas de electronica, popular electronics,rede,elektor,microelectronics defrancia que luego recordare,la querida radio practica de argentina y muchasotras.fui un botellero del gwbasic juntando partes,analizando ,programando.
en estas calurosas semanas de febrero del 2006 navegue por internet yencontre muchas sorpresas que me dan la pauta que el gwbasic esta vivo en elalma de muchos programadores.al mismo tiempo actualice mi mega programa a estasnuevas pc ahora tienen hasta cdrom ahora se descompacta desde el cdrom y seinstala solito en el disco c,en forma automatica. 2ff7e9595c
