PERSONAL SPELLING CHECKER¢¢BY BRYAN SCHAPPEL and BARRY KOLBE¢¢This speedy, powerful machine¢language program supports up to 10¢personal dictionaries. It's easy to¢use and works with most DOS files. A¢48K system and about 31,800 free¢bytes give you about 6,360 words per¢dictionary (counting about five¢bytes per word) -- as many as 63,600¢words altogether.¢¢GETTING STARTED¢Format a blank disk with DOS 2 or¢2.5, then use DOS menu option "H" to¢WRITE DOS FILES to the disk. This¢will be your Personal Spell Checking¢disk.¢¢ Next, copy PSC.EXE to this disk.¢Rename PSC.EXE to AUTORUN.SYS.¢Finally, copy DICTION.1 to this¢disk. This is a dictionary file.¢¢ Turn your computer off and place¢your Personal Spell Checker disk¢into drive 1. Remove all cartridges¢(hold down [OPTION] on an XL/XE) and¢turn your Atari ON.¢¢ At the prompt, insert a¢DOS-formatted disk that will contain¢your dictionaries (the monthly disk¢contains DICTION.1, a sample¢dictionary for you to use). You can¢use the program to create additional¢dictionaries. Legal dictionary¢filenames are DICTION.0 through¢DICTION.9.¢¢ NOTE: The program may only use¢one dictionary at a time. (For¢example, after proofing your text¢file with the first dictionary, you¢must stop, load the next dictionary¢file, and check the text again.)¢¢ If there are no dictionary files¢on your disk, the program chooses¢its built-in default dictionary.¢¢The top half of the screen displays¢information to help you use the¢program, such as the amount of¢available memory, your current¢dictionary and disk directories¢("catalogs"). The bottom half is¢your work area. This is where the¢main menu will appear.¢¢ Choose a menu item by typing¢the number or the first letter¢of that item:¢¢1) Proof Document¢2) Delete Word¢3) View Dictionary¢4) Add File to Dictionary¢5) Catalog¢6) Exit PSC¢¢Proof: Type in a filename. ("D:"¢isn't needed if you're using drive¢1.) The top of the screen shows the¢filenames of the current dictionary¢and file being proofed, the amount¢of free memory, the number of words¢in the dictionary and the number of¢words proofed so far. Below this is¢the context line, which shows the¢part of the sentence containing the¢word being checked. An unknown word¢is highlighted and displayed¢separately below. If it's spelled¢correctly, just press [RETURN] at¢the "Correct?" prompt. Otherwise,¢type in the correct spelling. To¢add the word to the dictionary,¢press [RETURN] or [Y]. Press [N] to¢skip it.¢¢Delete Words: Enter the word to be¢deleted from your dictionary. Then¢press [Y] after the prompt "Delete¢word? [Y/N]" to remove it.¢¢View Dictionary: This is for¢examining the current dictionary.¢Pressing any letter key displays the¢words beginning with that letter.¢For more words, press [RETURN].¢Words can be up to 29 characters.¢¢Add File: This lets you build a¢dictionary fast -- but do this only¢if you're sure that all the words in¢the document are spelled correctly.¢¢Catalog: This gives a directory of¢drives 1-4, or 8 for a RAMdisk.¢¢Exit: At this point you can save the¢current dictionary by putting your¢dictionary disk in drive 1 at the¢prompt and pressing [RETURN]. You¢can now restart or return to DOS.¢If you restart, the current¢dictionary remains in memory, but¢you can load one different¢dictionary if you want.¢¢The first two bytes of a dictionary¢contain the number of words in the¢dictionary. Next are 27 pointers to¢the beginning of each set of words,¢A-Z. This speeds up the search for¢a particular word. The 27th pointer¢points to one byte after the end of¢the dictionary. Third is a table¢containing the number of words under¢each letter.¢¢Finally there is the default¢dictionary of 26 words. These are¢AT, BUT, CAN, DO, END, FOR, GET,¢¢HOW, IN, JOG, KNOW, LET, ME, NO, ON,¢PUT, QUIT, RED, SO, THE, UP, VAN,¢WHO, XEBEC, YES, and ZIP. The first¢letter is not actually present in¢the word, and the last letter is in¢inverse video. Each single-letter¢word -- that is, "I," "A" and¢whatever other single letters you¢choose to call "words" -- is stored¢as a single inverse letter.¢¢If you choose a command by mistake,¢press [RETURN] at the first prompt¢to go to the main menu.¢¢When proofing a document, PSC¢creates a file called DOC.TMP and¢writes your corrected document to¢it. Your document disk must have at¢least enough room for one copy of¢the original document, or the¢proofreading process will abort.¢¢Since you can specify any drive as¢the source disk, the DOC.TMP file¢will also be written to that drive¢-- so if you have a RAMdisk, this¢program flies.¢¢When the file has been proofed¢successfully, the source file is¢given the extender ".BKP" (even if¢it already had an extender), and¢DOC.TMP is given the original¢filename.¢¢This program is not case-sensitive,¢so you can enter words in either¢uppercase or lowercase -- even¢inverse video -- and the program¢will convert them to normal¢uppercase. The only time this¢conversion is not performed is when¢you enter a corrected spelling for a¢word during a proof.¢¢ EXTRA BONUS: We've also included¢SPELL.M65, SPELL.DAT and SPELL.SUB,¢the MAC/65 source code files for¢the Spelling Checker. Due to the¢size of these files, they have been¢stored in MAC/65 "SAVEd" form.¢ You do NOT need these files to¢use the PSC program.¢
