Brouhabouha Forh repackaged

Description of the page content

Brouhabouha Forth, a Forth-94 sistem for QL written by Ewald Pfau in 1991-1994, repackaged with modern format documentation and other improvements.




This archive contains a distribution of QL Brouhabouha Forth, a Forth-94 Standard system for QDOS written by Ewald Pfau in 1991-1994.

The terms of distribution of the original program have been respected: all original files are included, in its own directory.

The latest version of this distribution can be downloaded from:

This distribution was prepared by Marcos Cruz (, in 2016-01, in order to make this Forth system easier to use and preserve it for the future.

Differences from the original distribution

  • The QDOS file header of the executable has been restored. It was missing in the old distributions found on the Internet (in ZIP or LHA archive formats).

  • Most library source files of the original distribution are Forth blocks files; they have been converted to text. The format of the comments and other layout details have been improved manually in order to make the sources easier to read and to use in the text version. Both versions, blocks and text, have been included.

  • The filename extensions of the source files have been changed after a modern convention: .fb for Forth blocks files; .fs for Forth text sources. They have been updated also in the sources, were some source filenames are used.

  • The filename "edb.hlp", a single block file which contains a key shortcuts cheatsheet of the blocks editor (but not used by it) has been renamed to "editorhelp.fb".

  • In order to protect the executable from loosing its QDOS file header again, it is included only in QDOS media images, which also contain the whole system, ready to be used on any QL or SMSQ/E emulator.

Library source files

QL Brouhabouha Forth includes the following optional library files.

Note: All ".fs" files except two have also a Forth blocks version (with the ".fb" filename extension).


Laxen & Perry’s 68000 F83 assembler.


Access to multi dimensional arrays.


Conversion between block files and ASCII files.


Binary sort.


Some Forth redefinitions for words from ANS Forth Core Extended, Double and String wordsets. As well some common definitions often needed, secondary evaluation of number division, and interpreter number conversion.


End of line conversion tool.


A Forth block with the blocks editor keys cheatsheet.


Tool for printing on EPSON printer, and for conversion of character sets in files, QL/IBM.


Random test of a dynamic heap.


Object Oriented Programming System, Version 3.1, by John R. Hayes, Applied Physics Laboratory Johns Hopkins University.


Extension to oof.fs.


Prime numbers search.


Forth blocks printing tool.


Files manipulation tools.


Misc extensions.


Graphics with sin table.

1. 112 KiB for code, 48 KiB for headers and 32 KiB for data. These values can be changed by adjust-sizes and then create a new executable with save-file. See Implementation characteristics and special behaviour in the manual.
2. With the block editor loaded as-is, for free use remain about 42 KiB for code, 19 KiB for data, 22 KiB for headers. See Implementation characteristics and special behaviour in the manual.
3. With the block editor removed, for free use remain about 59 KiB for code, 27 KiB for data, 23 KiB for headers. See Implementation characteristics and special behaviour in the manual.
