L/+Dimon1

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.

Dear Gus,

Since the assembler for CODE5 has now been published, I have written an
explanation of how this was developed and how it operates.  While doing
this I found a small change which improves the 40 columm printing.  This
is explained in the description of the code.

I hope that this will be is interest to members who might be able to
suggest improvements or want to experiment with it.
                           
The 40 column printing routine was produced, after some experimenting, to
give the best results I could.  This depends to some extent on the
original 80 column file and I wrote some comments on this which were
pubished in EUG20.

I have now re-written these comments and suggest that they might be
included in the info on EUG.  This would, I hope, avoid the 'higgledly
piggledy' - to quote one members comment - look of some of the submissions
to the mag.

The program VTYPE5 was included so that members could see how their files
would appear on the disc before they are submitted.  It also shows if the
file needs splitting as it will only print the part of the file which will
fit the memory allocated (HIMEM to &4000).

Unfortunately, the version published in EUG26 was an early one with the
wrong value for HIMEM.  The later version is on EUG24.  This needs two
small mods to make it work with CODE5.  These are -

               50*LOAD $.CODE5
              150CALL&9AA

This version allows the value of HIMEM to be changed but gives the value
of &2600 as on the discs if no address entered.

I have also written some notes on the menus as I thought that this would
be of interest and show what facilities these include.

Regards,

Richard
