!FORTH/Bugs
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

KNOWN BUGS
Version 1.0
1. SWAP has an error in it when it is compiled, it can leave the top two stack entries as they are rather that swap them.
2. The screen is not updated properly when it is partly covered by annother window.
3. INKEY does not always work properly.
4. The Caret is not implemented properly.
5. The current key focus is not set to !FORTH when a file is dragged to the !FORTH window.
FEATURES TO BE IMPROVED
1. Screen updating is slow, this will be improved but I don't know how (yet!).
2. Character variables, arrays, and strings will be implemented.
3. !HELP system implemented.
4. Multitasking.
5. Error Handling.
6. WIMP support.
