P/Edit1
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.

EDIT
====
A while ago I wrote a MODE 0 screen editor in BASIC as my scanner uses
this mode so editing is essential - sorry it's a little sl ow (I think its
the huge offset calculator starting ?&3000 DIV MOD DIV MOD DIV MOD
etc...).This is on the disk too.
For those looking at the listing everything is done using GOSUB's
instead of PROC's because there was one which wouldn't return p roperly (a
bug in BASIC??),and also there is less than 256 bytes of free memory if I
remember correctly which makes PROC's impossibl e to do as BASIC copies
the 6502 stack onto the BASIC stack during a PROC - resulting in a no room
error.
Further details appear in the EDITREM program
Since then I have given up on the BBC to edit scans - instead I send
them up a serial link to my PC as Windows BMP files and edit them in
'NeoPaint' then send them back when I've finished: believe me it is
faster in the long run.Incidentally this letter was typ ed on my PC too
Robert Sprowson.
$.EDIT
Type CHAIN"EDIT".Then at the prompt type the name,including directory,of the file to open.If necessary insert the disk with the file
on in the disk drive,the when the speaker beeps replace the original program disk.
CURSORS = move pixel pointer around the screen
SPACE = reveal where the cursor currently is
S = save the image to the file $.OUTPUT on the program disk
M = move the selected area.Drag a box out then press COPY.Drag the
moving box then press COPY to paste it
P = paste the image currently held on the clipboard ($.EDITCLP)
C = copy,same procedure as move
F = fill,first choose whether to fill Black/Grey/White,then drag
out a box to the area to be filled,then press COPY.The
clipboard is unaffected
B = box the area by dragging a box as usual,and leave it there on
pressing COPY
T = type text (DO NOT press delete) at the current cursor
position,if return is pressed the text is set in columns
E = call editor.Drag out an area,then press COPY.The chosen area is
saved and so is the current screen (to $.OUTPUT).The screen
mode then changes and the area can be edited using TAB and the
cursor keys.Press COPY to overlay the modified version.
