Speller/Technic
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
Watcher Technical Details If you dump the Dictionary file you will notice that it is arranged in alphabetical order and that the first 81 bytes do not contain any words. These bytes form a look-up table which Watcher loads into RAM. Each letter of the alphabet has three bytes, the first three are for A, the second three for B, and so on. The table contains details of where in the file (i.e. at what point in the file) the entry for each letter starts. The last three bytes contain the length of the file. By using 3 bytes (24 bits) the maximum length of the file is 2 to the power of 24. This I believe should cope with all but the most extravagant dictionaries. Since this is also the maximum length of a BBC file it is able to cope with any file. To save space the end of each word is marked by setting the top bit of the last letter or the word. So when dumping the file you will not be able to read this letter. By using this method there is no need to store the length of any word or to use up a whole byte just to mark the end of word. However it does mean that one letter words (i.e. A and I) disappear completely when the file is dumped. Watcher (i.e. Watch) reads in each word ignoring any punctuation and non alphabetical characters. Each space, or carriage return is used to represent a break in the word. It then takes the first letter of the word and reads the position of it's entry, which is used as the starting point for the search, and the following letter, which is used as the end point for the search. e.g. for the word "Disc" it would take the position of D as the start for the search and the position of E as the end of the search. A simple linear search (i.e. checking the first word in the file, then the second, then the third and so on) over this range would be far too slow once the dictionary got any where near usable size so another method is needed. I have adopted a binary search system. Using this system Watcher finds the mid-point between, in this example, the start of D and it's end (i.e. the start of E) and takes the word closest to this point. It compares this with the word it is looking for - the search word. If, alphabetically, the word from the file comes after the search word Watcher retains D as it's starting point but now resets the end point to be the same as the mid-point. Hence with one check half the words have been eliminated. Watcher now finds the mid-point between the original start and the new end. It again takes the word closest to this point and compares it to the search word, if the search word is alphabetically after this word the current mid-point is taken as the start and the current end (i.e. the previous mid-point) is retain as the search end point. Using this method everytime a word is looked at half the possibilities are discounted. Hence the search area is reduced by a factor of two each time so the name "Binary Search" results. The search is terminated by one of two events, either the word picked to be the mid-point is the search word, so Watcher can terminate the search knowing that the spelling is correct. Alternatively the search area becomes so small that no word can exist within it. When this happens the search has finished but with no results so the word is unknown. If Watcher comes across a word that does not have an entry in the dictionary it looks at it's list of new words. There are two lists of new words. The first is maintained in RAM and stores any words that Watcher finds during it's check. At the end of each text check these words are copied to the disc file C.NEWORDS - which as you may expect contains any new words found. When Watcher is first run, after reading in text and opening the dictionary file it looks for a file called C.NEWORDS. If this file is not found then Watcher creates it. If Watcher does find the file then any word that is not found in the dictionary, or in RAM is compared to words in the new words file. This file is just a list of words that have been dumped to disc from RAM after each check and have no order. Hence if Watcher must search the new words file the search is slow since the words have no order and a linear search must be used. If any word from the text is not found in the dictionary, in RAM or the new words file it is offered on screen for human checking. Depending on how the screen options have been set the word may just be ignored (i.e. if the No Test option has been chosen). If you tell Watcher that a word is correct then it will examine a flag to see what should be done with the word i.e. save, ignore or consult the user again as defined by pressing f0, f1 and f2. If you decide to save the word either through selecting the f1 "All Save" option or the f0 "Selective Save" and then pressing S the word will be stored in RAM until all the text has been checked. At the end all the RAM words are saved to the new words file. While the word is in RAM it may, of cause, be used to verify another word. It is important, for maximum speed, that once a new word file contains words that it is merged with the main dictionary. I have left the option not to merge the new words file with the main dictionary but would always advise that it is merged as soon as possible. A new word file containing even a modest amount of words may double the search time for each word. Constraints No word may be longer than 26 characters. I don't know if Watcher will operate on a second processor system. I would expect it to work though. Watcher will operate on Master machines but can be slightly temperamental at times. I have used Watcher on a Master 128 with floppy disc and on Master 128 with an Econet interface connect to a 40Mb Viglen hard disc operating off a SJ Filesever where the extra speed was clearly visible. I have not had a chance to test Watcher on a B+ but see no reason at all why is should not run as normal. Watcher will run a silicon disc. I have used it on a 32K Watford silicon disc, however sometimes it is necessary to trick Watcher into running where the RAM disc is not big enough to hold all the necessary file. My method is to only load the dictionary and text file onto the silicon disc. Then *LOAD Watcher from floppy disc, switch back to silicon disc and run Watcher using CALL &250B. Using a silicon disc it is feasible to use bigger than normal new word files because of the speed of access.
