P/+ppman1
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
MANUAL FOR PRETTYPRINT (6502 ROM image)
This file describes the ROM image PRETTYPRINT which adds 'OS_PrettyPrint'
support to the BBC in an identical manner to that supplied on Risc OS based
machines.
The manual is (C)1998 SPROW and software is (C)1997 SPROW
INSTRUCTIONS-
At any command line prompt,eg.the BASIC command prompt '>' type
ON A MASTER: *SRLOAD DRDIR 8000 <socket#>
*INSERT <socket#>
where <socket#> may be 7,6,5,4
ON A MACHINE WITH SWRAM: *LOAD DRDIR 8000
and press CTRL-BREAK to initialise.
The image will then be installed into the chosen socket where it will wait for
the user to issue one of the following two stimuli
OSWORD CALL-
A=&47 and X&Y point to a control block in memory
XY+00 4 byte pointer to null terminated string to print (low byte first)
XY+04 4 byte pointer to user dictionary,or 0 to use built in dictionary
(low byte first)
XY+08 4 byte pointer to null terminated 'special string' (low byte first)
XY+12 Source of string to print,00=RAM 128+socket=ROM
XY+13 Source of user dictionary,00=RAM 128+socket=ROM if XY+04 is non zero
XY+14 Source of 'special string',00=RAM 128+socket=ROM
COMMAND LINE-
*HELP "filename" where "filename" contains a valid wadge of text and
starts with a 15 byte block as though it had been entered
as an OSWord.
To make a file that is suitable for use in this manner is
really easy.You just take your prettyprint text and then
put the 15 byte OSWord block at the beginning of the file.
Because the OSWord block needs addresses putting in it,
you'll need to specify a SENSIBLE load address in the
file's catalogue entry.
EXIT MESSAGES-
Missing " - the command line had a closing ditto missing
Dictionary entry not found - an escape sequence number was out of range
Load address too low - the file specified on the command line loaded in at a
silly place in the memory map
File not found - the file specified on the command line doesn't exist
Tube hardware not found - the OSWord block specified data to come form the tube
KNOWN PROBLEMS/FUTURE ENHANCEMENTS-
No known problems
HISTORY-
V0.90 First release version,to the EUG disk user group along with an article
on word wrapping text
V1.00 Wordwrapping to current text window width implemented
WHAT PRETTY PRINT IS-
Pretty print writes a string pointed to by an osword control block,in addition
there are some special properties that it looks out for though:
* A carriage return causes a newline to be generated
* TAB causes a tabulation to the next multiple of eight chars
* Wordwraps,unless the words are separated by CHR$31 (used as a hard space)
* ESC (ASCII 27) indicates that a dictionary entry should be substituted
To use a dictionary entry,place a CHR$ 27 followed by an entry number to look
up in the range 1-255 (the entry '0' is used to look up the 'special string'
pointed to by XY+8).
There is a default dictionary,which doesn't contain all 255 entries,but you
may of course specify your own 'User dictionary' if the application you have
in mind uses alot of the same strings.eg.a chemistry related program.
Effectively this will result in text being compacted since whole words are
replaced by just two bytes.
DICTIONARY FORMAT-
Dictionary entries may recursively refer to other dictionary entries,nested
no deeper than 32 levels (otherwise the stack overflows).The first byte of the
entry points to the next entry,then there's text terminated by a 0 byte.So for
a file of N strings:
<offsettostartofstringTWO><1STstring$of255chr$orless><00>
<offsettostartofstringTHREE><2NDstring$of255chr$orless><00>
: : :
: : :
<offsettostartofstring(N-1)><(N-1)THstring$of255chr$orless><00>
<00><NTHstring$of255chr$orless><00>
