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.

CODEWORD TECHINICAL INFORMATION
Adding your own puzzles
THE puzzles are arranged in a text file like so:
GASKET PUMAS <--- 12 letters followed by carriage return
L E R O A U
INTEREST C N
N P S EWERS
TOSSES N R E
O ENTRANT
PROFUSE T * <--- note any character other than A-Z can be used to
R T N GRIEVE separate words; here I have used * to make sure
OTHER R N L the line is exactly 12 characters long.
P S EXORCISE
E A A I U G
ROYAL DIRECT
<carriage return>
NEXT PUZZLE <--- Beginning of next puzzle
and so on for all 10 puzzles. The default set of puzzles was arranged in
VIEW.
Memory Allocation
CODEWORD uses its own set of Times-style fonts. These are user-defined
graphics characters held in pages &9-C. The statement ?&367=15 sets bits
0-3 (i.e. 1+2+4+8) of the fonts flag at location &367 so that characters
224-255 (bit 0), 192-223 (bit 1), 160-191 (bit 2), and 128-159 (bit 3)
can all be defined. The statement !&36B=&0C0B0A09 sets the values at
&36B-E to &9-C, the PAGE number of where the character definitions are
located. If the program finds itself running on a BBC Master, INKEY-256=
253, then the characters are peeked out of memory and defined with
VDU23.
The text file containing the puzzles is loaded in at &1100; the
default set is called CWDATA1. BBC Master owners must therefore set PAGE
to &1700 or higher to play CODEWORD.
Main Procedures
add Adds the letter L% to the grid, prints a blank at the
appropriate position in the letter list. Correct co-
ordinate given by (L% MOD 13,13+L% DIV 13). E.g. for the
letter N, L%=13 so (L% MOD 13,13+L% DIV 13) = (0,14). Then
prints letter at right position in number list, see line
520. Sets byte in 'plyd%' to L%+1 (because 0 in the array
means that no letter has been assigned to that number).
init Initialisation routine. Loads the fonts and text file (see
text).
mssg(A$) Prints the string A$ in the special font at the centre of
the screen.
number(X%, Prints number A% at (X%,Y%) in small font. Note
Y%,A%) how correct graphics char given for each digit, e.g. for
A%=12, 232+12 DIV 10 = 233; 232+12 MOD 10 = 234. CHR$232 is
start of the 'small number' fonts. PLOT 0,-16,0 backspaces
half a character back in VDU5
play Prompts the player to a letter and number. String A$ should
contain something like A01, in which case N%=1, and L%=0.
Function FNokay will return FALSE if it's anything
different. Adds (if N%>0) or takes away (N%=-1=TRUE, the
result of doing ASCLEFT$(A$,1) when A$="") the letter from
the grid.
screen Shuffles the letters, draws the grid lines, prints CODEWORD
title, prints list of digits on the right hand side. Puts
the numbers on the grid, and chooses some letters to start
the player off.
shuffle Chooses the numbers to which the letters are assigned.
First arrange numbers 1-26 in random order in 'playd%'.
Then fill grid with numbers that correspond to the letters
given in the puzzle in the text file, e.g. value in
playd%?1 is the number assigned to the letter B.
sub Subtracts letter from grid, prints blank in number list and
restores letter to right position in letter list (see notes
on PROCadd).
tile(X%, Prints letter A% in big font at (X%,Y%), where A%=1 for A,
Y%,A%) A%=2 for B etc. excepting special case where A%=0 and blank
square printed. Correct group of 2x2 characters worked out
from 124+A%*4. E.g. for letter B, 124+A%*4 = 124+2*4 = 32.
Functions
lett(L%) Finds the number assigned to letter L% by searching the
'playd%' array. If it's in there, function will return with
0-25; if it isn't, function will return with 26.
okay Checks string typed in by player. If A$="" then they
pressed <RETURN> so end procedure with FNsolvd. If length
of string is more than 3, or letter isn't A-Z then player
mistyped. If the string is OK, then check to see that
letter hasn't already been played.
solvd Checks player's solution against actual answer. C% set to
TRUE to begin with, then if any letter in the player's grid
doesn't match, function will end with C%=FALSE.
