P/Edit2
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.

File contents
mode 0 screen editor comments Variables: M$ current message,DOTX & DOTY current cursor position,STRTX & STRTY start cursor position before dragging (BRX,BRY) & (TLX,TLY) are bottom right and top left x and y coordinates of the original box that was saved A is internal counter and inkey and general pass parameters thingy. F is always used as the file#. OVR is the isolated bit taken from the clipboard file as viewed in the order that it was saved and the order it is being loaded in in.FLG is set 0 if the chosen bit (see OVR) wasn't set and vice versa PASS is a counting loop used in the MODE5 module and also when drawing a box (hence will always be a mutliple of 2) SCRN is used in the MODE5 module,and is initially set to &140 less that the bottom of the screen memory (as in the genric section th at follows &140 is added back on) for the mode.LOC is the current byte in question,being poked SVTLX is used in the two versions of the loadin routine (see MODE5 module and around line 700) to keep the original value saved whil e the actual value is incremented TMPX and TMPY are used to provide compatibilty between routines - ie.to pass parameters and count things in loops CNSTY and CNSTX are used when dragging out a box and effectively set the stp of the FOR...NEXT loop to enable the box the be dragged from any corner HINDX and EINDX are used for when the appropriate whole selected bytes are to be saved.Home index is how many bits in from the MSB o f the byte the cursor is at and End index is how many bits in from the MSB too 23,0,10,12... is used to disable the cursor.If there are any suspicious +1's anywhere it is usually because natural numbers start an d 1 but the co-ordinate system starts at 0,0 Filenames: EDIT is the startup and load in part ; EDITTMP is used internally as a temporary file when the move option is chosen and will be del eted ; EDITCRE the core program which is where almost all execution time is spent EDITENL contains the pixel by pixel editor ; EDITCLP is the clipboard file in the format (strtx,strty)(dotx,doty)(bytes... To avoid the can't extend error ensure the disk is *compacted.No it won't run accross the tube as it pokes memory addresses Errors: within the core program only ; 'SIZE?' means that the selected area to zoom in on was greater than 30x40 ; 'WIDTH?' and 'DEPTH?' mea ns that the selected area didn't enclose any pixels ; 'CANNOT' is given by the paste command if there is no clipboard file on the di sk Blow by blow: EDIT>>> FX3,4 restores output to the screen when re-entering fron 'editenl' as it is turned off in that program to jab keys into the keyboar d buffer ; FX4,1 makes the cursors ASCii ; HIMEM is dropped as the message area is stored here later FX12,8 slows the keyboard repeat to prevent delays while the pixel-pointer catches up with the keyboard buffer EDITCRE>>> Is made up of many gosubs each of which are used by the command table right at te beginning.In order of appearance they are Keypresses are detected and if cursor keys then the pixel-pointer is move else check is it is one of the reserved words Save what was in the message area (eight letters each taking 8 bytes) just below screen memory then print the message using MOVE and VDU5 then restore those bytHighlight the cursor with a 2x2 box by starting (x-2,y-2) from the current cursor position the increasin g the co-ordinates.If the point is off the screen then nothing is plotted to avoid half the box appearing on the other side of the s creen mass calculation to locate any pixel on the screen using true (x,y) co-ordinates measured from top left (0,0) to bottom right (639,2 55) Expand a box by seeing which of the cursors was pressed and adding or subtracting from DOTn.CNSTX and CNSTY allow the box to be drag ged starting at any corner,although on pressing chrs(135) they are sorted into size order so that STRTn is top left and DOTn is bottom right.If the box has no depth or width then the user will be alerted of this Move box by adding to BOTH STRTn and DOTn instead of just DOTn as above.On pressing chrs(135) it returns Save boxed area to nearest whole byte (the individual bits required from each end is calculated later) Loadin by getting a byte from the file,ANDing it with a mask,and then checking whether the chosen bit is set.Then get byte from scre en memory,AND it with a negative mask to ensure the selected bit is set 0.Or the two together Clear the area temporarily renames the clipboard file,then creates its own by saving a load of VAL(M$),using M$ to save variable nam es.Load in that file,and restore the clipboard.255=white;0=black,170=(10101010) therefore grey Select black,grey,or white.No default,if the question is not answered it is asked again. Get co-ordinates of the area last selected in the clipboard file.If not exist then print 'CANNOT' in the message area One pass version of the draw a pulsing box.This is only used by the box drawer so that the box is permanently left on the screen Enter text (delete and copy are disabled).Pressing RETURN puts it in columns.Ex-or's it so that if crossing a black/white boundary i t appears 50:50 Procedit drags a box,saves the area,saves the entire screen to $.OUTPUT,then chains the mode5 extention module EDITENL>>> Openin the file,to get co-ordinates,remove the cursor with VDU23,define variables and those with I want to save unaltered for later As with loadin above,except that is flag is set then a whole square is coloured in with a for...next poking 255 into the screen memo ry Print current pixel position,which can be increased up to the limit of the screen (29,39). If tab pressed then ex-or whatever was there with 255 but if pressed chrs(135) then stop the editor and save Reverse of loadin except that if TLX~8 isn't zero then some blank bits must be saved in the byte before the 'pixels' (squares on the screen) can be evaluated otherwise the file would be ((HINDX+(8-EINDX))*Y too short Print 'reloading' then emulate what '$.EDIT' does (loads in the screen,turn on the first pixel at TLHC) then insert 'P' into the key b buffer and run '$.EDITCRE' which then jumps to 'paste' mode to insert the new version R.Sprowson 3/9/95
