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.

******************************************************* Richard Dimond, 5 Briary Court, SIDCUP, Kent, DA14 6HZ. Tel. (0181) 302 2395 ******************************************************* Dear All, I was interested in Robert Sprowson's Wordwrap coding in the last mag as he has used the same routine that I have used in my codes 6 & 7. This made me look at my coding again as I had only used space for the routine to check back for while he uses all below CHR$48. My coding will check for all characters which are neither letters nor numbers and enables long strings - eg. M/code - to be printed provided they contain these characters so that they are split up if necessary. I have found two characters which should not be used - the apostrophe and the slash - as they split words like don't, Robert's and M/code. I have added a routine 'chkchr2' which is described in my article on the coding to check for these. I have also included the '_' character in 'chkchr' so that solid lines may be printed. The coding is now CODE8 and I have included the assembler listing, to which I have added REM lines and used ASC" " in check routines to make the coding clearer, and explained this and also the menu system so that you may see how the discs work. I had many problems to shorten the menu sufficiently for it to work with the additional DATA lines with PAGE at &1D00 and had to transfer the print routines to the 'PRINT' program and this caused the problem of transferring variables between the two programs. The numerical variables were easy to transfer by using the integer variables. The three string variables were a problem though and I tried various addresses until I found that I could use the bottom of the stack. I have revised my info part of the Information on EUG to cover these changes as there should no longer be chances of locking up the program now and I would suggest you all re-read them. I have also made some small changes the VTYPE program which I suggest you use to check your files. The two CALLs to the coding are now 'clear' and 'print' as in the coding and coding number to 8. Also line 20 sets the variable 'skp' at &82 to zero as I found this could get set to another value and cause the perforation skip routine to print several blank lines. I also read with interest Chadders suggestions to produce a better and hopefully an error free magazine and would say that I have already offered my help in this way. Had I checked EUG36 before it was published, there would have been no problem. I know that Gus does not get sufficient submissions to plan even one issue ahead to enable this to be done. May I too encourage you to send in your submissons? Regards, Richard As Ive said before and you pointed out, time is the problem. It is November 7 now, this disc was due out at the beginning of October.
