V/+LISTO

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
                             LISTO8 UTILITY
                      Written in 6502 Machine code

THIS file describes the program LISTO8 which adds a new listing option
to BBC BASIC I, II and IV (Not tested on III). This new option splits up
multi-line statements (ie. ones with ':' separators).

Instructions
AT any command line prompt, eg the BASIC command prompt '>', type:
      >*LISTO8 <RETURN>

The program will then install itself into page &C00 (the CHR$ definition
buffer on the BBC and Electron or Econet workspace on the Master 128) 
where it will sit and wait until a program is LISTed.
   If, on listing LISTO bit 3 is set then multiline statements are split
onto new lines, even taking into account the other LIST options (such as
'Indent FOR...NEXT' loops).

Known Problems/Future Enhancements
No known problems.
Not tested on American BASIC III.
Repointing of the 'reset' vector, to allow the pressing of BREAK, as for
example may be performed when pressing <SHIFT><BREAK> to boot a disk.
