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.

"WINEDIT"
=========
If you have access to an Acorn machine
with the Risc OS desktop,you'll have
noticed the fancy text entry boxes.
These allow cursor editing of the
entered text,which,if long enough,is
centred in the box,and scrolled from
right to left.
The FN I have written may be
incorporated into all your programs
that require text input,as it's better
than BASIC's INPUT command which uses
OSWORD 0.
The parameters passed when calling the function allow the setting of:
1)Default string eg."TextFile"
2)Window width - odd numbers will work
best
3)Max length - a beep (VDU7) is emitted
if the string is too
long
4)Window position - where on the screen
the box is to
appear.
5)Background colour - your choice.
The cursor editing status,using *FX4 is
preserved during the FN,as are the
window settings before calling it.
However,you'll need to set the text
background colour back to whatever it
was before calling the FN - this isn't
preserved.
As usual,I've only done half a job - as
an exercise for the reader perhaps
someone could add a test for valid
characters eg.if a filename is required
the filename cannot contain a space so
this should be ignored.
I suggest a use of INSTR,or the
purchaseof a Risc PC - tell me how you
get on
