Vision 6.2 VISION SYSTEM ================= (v 6.2 01-Jan-1993) by Maurizio Ammannato (M) 1993 Maurizio's House [<HyperText>] Press the ENTER key now to know some HyperText navigation rules. Welcome to VISION System ======================== Vision is a <Free Form Textual Data Base> System. The first access method isthe usual hierarchical Chapter/Pages two-levels access. In this way you canread newspaper articles, documents, books, dictionaries, glossaries, helpfiles ,etc.) just choosing the Data Base you want read (first layer), thenits Chapters (second layer), finally the chapter' Pages (third layer). Youalternatively access a VISION Data Base using <Hyper Text> technique, thus<navigating> text through its <keywords> (fourth layer). This package allowyou to build your own Text Data Base by yourself. It isn't just a "Read Only"package. Licence Fee =========== The package is completely free of charge for personal use. Do as many copiesyou like for you and your friends. However you're not allowed to make anykind of profit or to do any commercial activity related to VISION. MY PREFERRED SENTENCE ===================== "The best VISION for a Company should be its people jobs safeguard, lettingthem to prosper being at peace with the men and with God. The STRATEGY shouldbe the way to realize this VISION, maintaining the Company's businessgrowing, productive and profitable. Not easy at all. That's why you shouldhave firstly a depth MISSION in your life." (Oiziruam Otannamma) Enjoy VISION System ! Maurizio Ammannato Via Preguda N.60 22049 Valmadrera (CO) --------------------- I T A L Y Decompressing Archives ====================== Create a <directory> called VISION (DOS command MD) and copy there VISION.ZIPfile and eventually all related Textual Data Base with the extension .ZIP(which means compressed via PKZIP.EXE utility). Using the companion PKUNZIP.EXE utility (which you can find on many BBS)decompress them as following : C:\VISION\pkunzip *.zip In this way all .ZIP archives will be 'unzipped'. The VISION package must have the following files : - VISION.EXE engine program - VIS_OVL.EXE its overlay - VIS_CRE.EXE create your own Textual Data Base (import) - VIS_UPD.EXE from .DB database back to .UPD ASCII file (export) - LHA.EXE LHA compressor - LHA213.EXE self extracting LHA documentation and disclaimer - VIS_SORT.EXE sort utility - VIS_FONT.EXE change VGA screen text font - VISION.CFG configuration file (default=color) - VISION.COL configuration file for color monitor - VISION.BW configuration file for mono monitor - VISION.MSG comment/help file for VISION.EXE (default=English) - VIS_OVL.MSG comment/help file for VIS_OVL.EXE (default=English) - VISION.ENG VISION.EXE comment file in English - VIS_OVL.ENG VIS_OVL.EXE comment file in English - VISION.ITA VISION.EXE comment file in Italian - VIS_OVL.ITA VIS_OVL.EXE comment file in Italian - VISION.DOC VISION documentation in printable format (English) - #_VISION.NDX documentation in VISION format (INDEX) - #_VISION.DB documentation in VISION format (DB) - WHATIS.NEW brief description of new features Demo files: - VISION.DDD example file for VISION.DIR option - #_PIPPO.UPD example source file to build new VISION DB - #_PLUTO.UPD example source file to build new VISION DB with HyperText facility Decompress all .ZIP Textual Data Bases (TDB) you have in the directory usingthe same procedure as before; after that copy all .ZIP files in a back-updevice and REMOVE all .ZIP (i.e. "ERASE *.ZIP") to save precious disk space. To decompress <LHA> documentation: C:\VISION\lha213 VISION Configuration ==================== Check through your favorite Text Editor, or WP, the configuration fileVISION.CFG and change what you need or wish to change. Foreground color numbers can range from 1 to 31 (after number 15 the color isblinking). Background from 1 to 7. The following is the complete list of options you can set : '---------------------------------- VISION.CFG config file SCROLL_SPEED=7 number of secs for automatic scrolling (Alt-A) SORT=BYNAME or BYDATE or NO sort option EDITOR=filename full path of your preferred Text Editor (Alt-E) COMPRESSION=ON/OFF to allow or disallow LHA Data Bases compression TMP_DEV=dev/NO the fastest device in your PC to allow temporary storage WDW_END=@@@ break-characters for Keyword Window SKD_LFT=60 source keyword left delimiting character SKD_RGT=62 source keyword right delimiting character TKD_LFT=17 target keyword left delimiting character TKG_RGT=16 target keyword right delimiting character F_DBW=15 foreground Data Base Window (DBW) color B_DBW=7 background Data Base Window (DBW) color F_BOT=0 foreground Help Desk color B_BOT=2 F_COM=0 foreground DBW comment line F_HIG=14 foreground DBW data base name F_IDX=15 foreground Index Window (IW) color B_IDX=1 F_TDX=7 foreground IW text color B_TDX=1 F_DOC=0 foreground Document Text color B_DOC=7 F_REV=0 foreground reverse Index title B_REV=6 F_ASK=15 input window B_ASK=4 F_FND=14 founded string color Color or Monochrome =================== You can easily change color attributes modifying .CFG file colorparameters.To make your life easier, if you have a monochrome screen, copydirectly VISION.BW to VISION.CFG file using DOS COPY command: C:\VISION\COPY vision.bw vision.cfg Compression =========== From VISION version 6.2 you can optionally use the compression feature.Firstly write: COMPRESSION=ON in the VISION.CFG configuration file. Then,when you use VIS_CRE program (or Alt-B command from VISION main window) tobuild a new Textual Data Base from its source FILENAME.UPD file, you get anew file with .DBC extension (no more with .DB extension as before)compressed using LHA program (the last "C" character in the data baseextension stands for Compressed). Doing that you can save disk bytes in theratio of about 8 to 1 (a filename.DB of 100.000 bytes can be reduced down to12.000 bytes in the compressed filename.DBC). Executing VISION you see a small "c" after the Data Base size number incorrespondence to the compressed .DBC data base. (If you don't use thecompression option everything remains the same as in the previous VISIONversions). Choosing the highlighted data base name (ENTER key) with .DBC extension,VISION executes before LHA to decompress it, then shows its text as usual.Due to LHA speed, the decompression activity doesn't take no more than fewseconds (depending on .DBC size and PC CPU speed). You can make some tests before deciding if to use or not this option. Thedefault setting is "ON". Converting .DB to new .DBC format ================================= 1) Set COMPRESSION=ON in VISION.CFG file. 2) Execute VISION 3) Move the bar up to data base name to covert 4) Press Alt-U keys to generate original ASCII .UPD file, then confirm 5) Press Alt-B keys to recreate the data base, now in compressed format 6) Give its name without any extension (the same name of point 3) 7) Write new data base comment line (if you wish the same as before) 8) Now, after compression, you have to see a "c" on the right of the filesize number which must be much less than before Converting .DBC to old .DB format ================================= 1) Set COMPRESSION=OFF in VISION.CFG file All other points are the same as before. *************************************************** USE COMPRESSION OPTION TO SAVE A LOT OF DISK SPACE! *************************************************** Temporary Storage ================= VISION and LHA work better if they have a fast device for temporary storage(some .TMP files etc.). If you have such kind of device (i.e. a RAMDISK orVIRTUAL disk on for example "F:" device), write TMP_DEV=F: in VISION.CFGconfiguration file. Otherwise write TMP_DEV=NO to don't use this option. VISION.MSG Message file ======================= Edit VISION.MSG messages file to change what you need (i.e. from my Italian-English to Queen's English, etc.) To change language file use COPY DOS command : C:\VISION\COPY vision.ita vision.msg to have the Italian comments/help. You can obviously create a newcomment/help file with your own language; i.e. for Spanish : - copy VISION.ENG into a new file VISION.ESP (DOS "COPY VISION.ENG VISION.ESP") - modify the new file with Spanish translation using a TE or WP (Text Editor or Word Processor) - copy new VISION.ESP into VISION.MSG (c:\vision\COPY VISION.ESP VISION.MSG) ================================================================== New comment strings MUST MUST have the same LENGTH of the old ones ================================================================== Executing VISION ================ Before executing VISION for the first time, verify to have available at leastone TDB (Textual Data Base) with both .DB and .NDX files. You must at leasthave the VISION files. You can create a new one by yourself (see below) ordownload some from a BBS. Remember to decompress them if ZIPped as explainedbefore. You have two different ways to execute VISION. 1) MENU MODE. Typing VISION at DOS prompt, you enter into Main Menu Windowwith the list of available Data Bases (see below): C:\VISION>vision 2) COMMAND LINE MODE. Typing VISION followed by data base name at DOS lineprompt, you enter directly into Index Menu from which, using ESCape command,you come back directly to DOS : C:\VISION>vision b_netw If you have a VGA monitor you can execute vision typing VGA instead ofVISION. This allows VISION to load into PC ROM a new text font (modern-d)resulting in a more readable text: C:\VISION>vga Also in this case you can enter directly into the Index Menu writing VGAfollowed by data base name: C:\VISION>vga #_vision to have on line VISION documentation. VISION Data Base Structure ========================== Before going on, it's a good idea to define the Textual Data Base structureused by VISION. ********************************** A VISION Data Base has FOUR layers ********************************** 1) Data Base Layer (list of all available Data Bases names, up to 100) 2) Title Layer (list of all Data Base Titles, no limit) 3) Page Layer (text pages of selected Title, no limit) 4) Keyword Layer (window text on selected word, no limit for keyword number, 16 windows in depth for each keyword) Two examples ------------ #_VISION Data Base: . Name, comment, creation date and size => Data Base LAYER (1st) . Chapter titles => Title LAYER (2nd) . Vision document Pages => Page LAYER (3rd) N_GLOSSA Data Base: . Name, comment, creation date and size => Data Base LAYER (1st) . Glossary Terms => Title LAYER (2nd) . Term Description => Page LAYER (3rd) . Keyword Comment => Keyword LAYER (4th) Main Menu Window ================ In the Main Menu, you can see at the same time up to 15 available Data Baseswith related comment, last update data and size. The limit of available TDBis 100 Data Base. Press Alt-H keys to get an on line help. ******************************** Alt-H to get VISION on line HELP ******************************** Help - MAIN MENU Available Commands (1st) ========================================= Alt-B Build New Data Base PgDn Page Down Alt-C Change Data Base Comment Line PgUp Page Up Alt-D Delete Data Base Title Up Alt-E Edit Source ASCII file (.UPD) Title Down Alt-R Restore Original Index Home Top of List Alt-S Sort Title Index Ascending End Bottom of List Alt-T Sort Title Index Descending ─┘ Open Data Base Alt-U Rebuild ASCII UPD file (EXPORT) ESC Exit Use Up/Down arrows or PgUp/PgDn to navigate, Alt-H for on-line help. Once onthe line of chosen DB (highlighted color) the ENTER key allow you to open theTitle Menu (you enter into 2nd layer). *************************************** ENTER key to OPEN highlighted Data Base *************************************** Initially TDB Titles are indexed sequentially (first record found, firstrecord in DB). You have two possibilities to change the indexing method bypressing ALT-S or ALT-T keys. These two commands tell VISION to sorthighlighted index by alphabetical ascending (ALT-S) or descending (ALT-T)order. ******************************************* Alt-S Alt-T to index differently Title list ******************************************* Any way Alt-R option restores the original indexing method. ***************************************** Alt-R to RESTORE original indexing Method ***************************************** From Main Menu you can directly edit a new/old VISION source .UPD file. Touse this option you have to declare before, in VISION.CFG file, the preferredText Editor with its FULL PATH and EXTENSION. Then, non depending on whichhighlighted name you are, press together Alt-E keys and give the filenameWITHOUT .UPD extension. If you use an editor called EE, in \EDITORS\directory on D: device, write in your VISION.CFG the following path: ........................ EDITOR=D:\EDITORS\EE.EXE ........................ ************************************ Alt-E to EDIT source ASCII .UPD file ************************************ From Main Menu you can also directly build a new VISION Data Base. Nondepending on which highlighted name you are, press together Alt-B keys andgive the New data base name WITHOUT .UPD extension (you must have this ASCIIfile on VISION directory). ************************************** Alt-B to CREATE new Data Base (IMPORT) ************************************** You can also rebuild the original .UPD ASCII file from main Menu, 1) move thebar on the Data Base name then 2) press Alt-U. You are required forconfirmation. ****************************************** Alt-U to REBUILD source .UPD file (EXPORT) ****************************************** To delete an existing Data Base, move the bar up to selected Data Base nameand press Alt-D keys. Before removing highlighted Data Base, you are requiredto confirm that. This command DOESN'T cancel the related .UPD source file butonly .DB (or .DBC), .NDX and .KEY files. ************************************* Alt-D to DELETE highlighted Data Base ************************************* Title Window ============ Once on TITLE Window, press Alt-H keys to get the following on line Help : Help - TITLE WINDOW Available Commands (2nd) ============================================ PgDn/Up Page Down/Up / Title Up/Down Alt-H This Help Home/End Top/Bottom List F1 Search String F9 Search String Globally F2 Search Again F10 Global Search Again ─┘ Open Document ESC Exit Use Up/Dn arrows and PgUp/PgDn keys to navigate this list. If you have a long list you can use F1 key to quickly search the title youneed, F2 to search again. You can search also for a piece of word, i.e."etw". In this case all words having "etw" will be displayed. F2 search againusing same search string. ********************************************* F1/F2 keys to SEARCH a word in the Title list ********************************************* Using F9/F10 you search instead for words line per line across documents. Anexample. Let imagine you want to search the word "disciple" in the NewTestament. 1) be in New Testament index window (Title level) 2) press F9 and give search string "disciple" 3) VISION finds search string in a book title 4) enter in the book (ENTER key) 5) press F2 to search same string inside the document 6) press ESC to come back to Index window 7) press F10 to search again at book title level (index) The difference between two above searching methods is that F1/F2 keys searchthe string within the index comment line (Index level), while F9/F10 keyssearch the string in the entire Data Base. **************************************************** F9/F10 keys to SEARCH a word in the ENTIRE Data Base **************************************************** Opening Document ---------------- Move bar up to desired title, then press the ENTER key to open relateddocument. ************************************** ENTER key to OPEN highlighted Document ************************************** Document Window =============== Once in Document window press Alt-H keys to get the following help: Help - DOCUMENT Window Available Commands (3rd) =============================================== TAB/s-TAB Scroll Text Right/Left s-Home Left Scroll Home (col 1) Alt-A Automatic Scroll On/Off PgDn/Up Page Down/Up Alt-F Write Document to File / Line Up/Down Alt-M Mark Document Position Home/End To/Bottom List Alt-J Jump to Mark (Alt-M) -/+ Dec/Incr Scroll Speed Alt-P Print Document F1 Search String -/- Keyword Navigation F2 Search Again ─┘ Open Keyword ESC Exit (s-TAB = Shift TAB keys) (s-Home = Shift Home keys) Up/Down arrows, PgUp/PgDown and Home/End keys allow you to quickly navigateacross Document Window. ************************************************** Up/Down,PgUp/PgDown,Home/End to navigate DOCUMENTS ************************************************** While Left/Right arrows let you navigate through keywords (if they exist) ************************************** Left/Right Arrows to navigate KEYWORDS ************************************** Reading Long Document ===================== Reading long document you need some functions to emulate real book reading. The first one is to mark a position for latter retrieve. Use Alt-M when youwant stop reading at a specific position (a soft beep advises you of workdone). Once you are back to same document use Alt-J to jump to mark. With nomark, Alt-J jumps to first document line. ****************************************************** Alt-M and Alt-J to MARK a position for later retrieval ****************************************************** If you want to read document without using arrows for navigation, you can usethe Alt-A automatic scroll option. VISION has a default value of 7 secondsdelay time between scrolling (see in VISION.CFG the SCROLL_SPEED option) sothat you can read it relaxed and quite. Use plus key (+) to slow downscrolling speed or minus (-) key to increase it. Keyword Window ============== Once in the a <Keyword Window>, press Alt-H keys to get following Help: Help - Keyword Window Available Commands ======================================== Alt-P Print Window Text PgDn/Up Page Down/Up Alt-F Write Window Text to File / Line Up/Down -/- Keyword Navigation Home/End To/Bottom List ─┘ Open Keyword ESC Exit Because in a Keyword Window you can find other keywords, use Left/Rightarrows to navigate these new keywords. You can have up to 16 Keyword Windowsin depth. ******************************************************** Up to 16 Keyword Windows in depth for each DOCUMENT word ******************************************************** How Many Keyword Windows ------------------------ When at document level (3rd layer), each word can be a keyword. If a documenthas for example 1000 words, you can have at the maximum 1000 keywords forthis level. Once open one of these 1000 keyword, you enter FIRST LEVELKeyword Window where you can find other keywords (in a Keyword Window you canfind about a maximum of 100 words per screen). Then you can choice one ofthem and enter in the SECOND LEVEL Keyword Window, and that up to 16 LEVELSKeyword Windows in depth. If we have for example a Data Base with 100 documents, each document with1000 words and assume that each of them are a keyword, and each of them opensa FIRST level window with about 100 keywords per window, up to 16 LEVELS indepth, the maximum number of Keywords Windows we can have for that Data Baseis the following : 100x1000x100x16=16,000,000 VISION Data Base Technical Structure ==================================== VISION System works using two different files, the index file with .NDXextension and data base file with .DB extension (or .DBC if compression isON). If Data Base uses also keyword option, VISION creates in this case athird file with .KEY extension. The following is its structure : 1) Index record title (78 bytes 78 character) 2) Physical DB address (2 bytes integer) 3) Length of document (4 bytes long integer) 4) Position of the Mark (2 bytes integer) 5) Reserved for later use (2 bytes integer) The Data Base structure is depending on ASCII document maximum line length.VIS_CRE program (executable directly at DOS level or using Alt-B command onVISION) before building a new Vision Data Base, displays the maximum textline length which is used to determine the simple Data Base structure: 1) Comment line (variable length) But you have to don't care at all of this technical info, you have only tofollow these very simple instructions to create your new data base. Creating New Free Form Textual Data Base ======================================== A) Building New Source ASCII File --------------------------------- Take your favorite Text Editor or use Alt-E option from Main Menu to edit anew source file called i.e. #_PIPPO.UPD (the .UPD extension is a MUST) andwrite your info in the following order : 1) First row will become FIRST index record 2) from second line up to the special break-characters line, write documentlines (pay attention to don't write the following special combination ofcharacters '@#$' at the line beginning). 3) special break-string combination to close the document; that is a '@#$' atthe beginning of the line. Look at the following simple #_PIPPO.UPD example : ---beg of file----- (don't insert this line in your file) NETWORK ======== The network is.... .................. .................. [@#$] (Don't write these squared brackets in real file) SUPER-CENTER ============ The supercenters are.................................... ........................................................ ........................................................ ........................................................ ........................................................ ........................................................ [@#$] (Don't write these squared brackets in real file) PROTOCOLS ========= You need protocols when you have to exchange information with other people/computers. The language is one of above protocols. ---end of file----- (don't insert this line in your file) ********************************************************** DON'T insert the break-string at the BEGINNING of the file ********************************************************** **************************************************** DON'T insert the break-string at the END of the file **************************************************** *********************************************************** DON'T put BLANK lines between break-string and FIRST record *********************************************************** B) Creating a VISION Data Base ------------------------------ Once done this ASCII test file, on VISION Main Menu, press Alt-B keys andgive its filename without any extension. This file MUST reside in same VISIONdirectory. ****************************************************** .UPD source files MUST be in the same VISION directory ****************************************************** You can also use VIS_CRE program at DOS level without entering VISION MainMenu : C:\VISION\vis_cre #_pippo This program creates #_PIPPO.NDX with three master records (NETWORK,SUPER-CENTER,PROTOCOL) and the #_PIPPO.DB (or .DBC) data base with text. After VISION has created these two files, it asks for a DB comment line. (Youcan also change this comment later, on Main Menu press Alt-C keys onhighlighted name). See and use this example to understand how to build or to modify a sourceASCII .UPD file. #_PIPPO.UPD must be in the VISION delivery disk or ZIParchivie. *********************************************************** USE #_PIPPO.UPD file to understand how to build a VISION DB *********************************************************** New Data Base from existing ASCII File ====================================== This procedure is the most common use of VISION because you have often some.DOC/.MAN/.TXT/.HLP files in printable or listable ASCII format and you wantto transform them in the more readable VISION format. VISION can very easilytransform this ASCII files in a Textual Free Form Data Base. ******************************************************** VISION can quickly transform ASCII files in FREE FORM DB ******************************************************** A) Modifying Source ASCII File ------------------------------ Take the ASCII file you want to convert and rename it with the .UPD extension(i.e. PIPPO.DOC in #_PIPPO.UPD); remove all extraneous lines (top of formcharacter, page break, etc.) and do exactly the same procedure as to build anew VISION source .UPD file. Example of #_PIPPO.UPD ASCII file to convert ------------------------------------------ - Pag 1 - NETWORK ======== The network is.... .................. .................. TOF (Top of Form printer command) - Pag 2 - SUPER-CENTER ============ The supercenters are.................................... ........................................................ ........................................................ ........................................................ ........................................................ ........................................................ TOF (Top Of Form printer command) - Pag 3 - PROTOCOLS ========= You need protocols when you have to exchange information with other people/computers. The language is one of above protocols. Now remove ALL EXTRANEOUS lines, i.e. the "Pag nn" lines, the "TOF"characters, the blank not useful lines, then follow the same procedure asbefore to create new source file so that the original PIPPO.DOC looks likethe following #_PIPPO.UPD file : ---beg of file----- (don't insert this line in your file) NETWORK ======== The network is.... .................. .................. [@#$] (Don't write these squared brackets in real file) SUPER-CENTER ============ The supercenters are.................................... ........................................................ ........................................................ ........................................................ ........................................................ ........................................................ [@#$] (Don't write these squared brackets in real file) PROTOCOLS ========= You need protocols when you have to exchange information with other people/computers. The language is one of above protocols. ---end of file----- (don't insert this line in your file) Once PIPPO.DOC has been modified in this #_PIPPO.UPD way, enter VISION Mainmenu and press Alt-B keys to generate new DB. Updating an Existing Data Base ============================== The best way to update a VISION DB is to : 1) enter VISION Main Menu (1st level) 2) move the bar to Data Base name 3) press Alt-U keys and confirm Now VISION creates again original .UPD source file, then : 4) press Alt-E keys and give its name without any extension 5) change what you need to change or update or add 6) come back to VISION 7) Alt-B keys to recreate VISION Data Base (.DB[C], .NDX and eventually .KEY) Erasing Data Base ================= Enter VISION Main Menu, move bar on Data Base to remove, then press Alt-Dkeys. VISION removes only .DB, .NDX and .KEY files; it doesn't delete the.UPD source ASCII file. Sort Option =========== You can have the list of available TDB (Textual Data Bases) sorted in threedifferent ways (first Menu Window). Write in VISION.CFG file your sorting choice. SORT=BYNAME It sorts Data Bases by names. SORT=BYDATE It sorts Data Bases by date (last equal first) SORT=NO VISION doesn't sort at all. Using SORT=NO and VISION.DIR option, you can decide by yourself the DataBases order (thus you get in main Window the exact order of VISION.DIR file). Changing the Main Menu List =========================== Renaming BOTH files (.NDX and .DB file) with a name of your choice, VISIONsorts automatically them by new alphabetical order putting them in theposition you prefer (if the sorting option is set on BYNAME). For example : N_...... = network related data bases P_...... = product related data bases S_...... = services V_...... = various and generic data base $_...... = pricing data bases .. = ............................... Simply changing the name of your DB (and related .NDX and .KEY file), you geta different classification. For example if you want to put #_PIPPO Data Basein first Main Menu line, execute the following DOS command, at DOS prompt, inthe VISION directory : C:\VISION\rename #_pippo.* !_PIPPO.* to be sure to change all #_PIPPO DB related files. Directory Option ================ When VISION starts, it firstly look for a file called VISION.DIR. So that youhave two different VISION behavior : 1) VISION doesn't find it in current directory. Then VISION looks for files on current directory as usual. 2) VISION finds this file. Then it uploads DBs into Main Menu following VISION.DIR directive. In the last way you can have your VISION files anywhere in your PC. Look atthe example for a better understanding. ***************************************************************** Using VISION.DIR option you can have DB files ANYWHERE in your PC ***************************************************************** VISION.DIR example ================== D:\VISION\#_VISION (.DB .NDX and .KEY files on current dir) C:\BIBLE\B_NEWT (.DB .NDX and .KEY files on C:,in \BIBLE\ dir) G:\V_PRESS (.DB .NDX and .KEY files on G:\, optical disk) ******************************************************* YOU MUST GIVE THE FULL PATH (DEVICE,DIRECTORY and NAME) ******************************************************* You have to build that VISION.DIR file using your preferred text editor.VISION.DIR must reside in the same VISION programs directory. Give a look toVISION.DDD, an example file in the distribution disk. When you load a new data base, remember to update VISION.DIR file otherwisethe program will ignore it. ************************************************** REMEMBER to UPDATE VISION.DIR when adding a new DB ************************************************** N.B. If the compression is ON, VISION executes before LHA to decompress the .DBCfile (every where it is on PC) into the .DB format file, which is temporarystored in the SAME VISION directory. In this way, if you have for example a"write once" optical disk containing VISION files, VISION decompress the database not on the source device (in this case the optical disk) but into anerasable device (where it is supposed VISION programs reside). To Create Hypertext Document ============================ To build document in <Hyper Text> way you have to remember three main things: 1) how to declare a <SOURCE keyword> 2) how to mark a <TARGET keyword> 3) how to write a <Keyword WINDOW> HyperText Parameters in VISION.CFG ---------------------------------- Give a look at VISION.CFG file (TYPE it or use a Text Editor). You have tofind the following parameters: WDW_EWND=@@@ this means you declare this three characters as the break-string to let VISION understand where a Keyword Window text stops. SKD_LFT=60 source keyword left delimiting character SKD_RGT=62 source keyword right delimiting character these characters delimit the text word you want be a text keyword TKD_LFT=17 target keyword left delimiting character TKG_RGT=16 target keyword right delimiting character for each SOURCE keyword you have to declare a TARGET keyword using these two delimiting characters Now an example. Let's imagine to have the example as before (#_PIPPO.UPD) towhich we want add HyperText facility. Call this new file #_PLUTO.UPD. ********************************************* See #_PLUTO.UPD file for an Hypertext Example ********************************************* ---beg of file----- (don't insert this line in your file) NETWORK ======== The <network> is....(here "network" is the 1st SOURCE keyword) .............................................................. .............................................................. [@#$] (Don't write these squared brackets in real file) SUPER-CENTER ============ The <supercenters> are............ (2nd SOURCE keyword) ....................................................... ....................................................... ....................................................... ....................................................... ....................................................... [@#$] (Don't write these squared brackets in real file) PROTOCOLS ========= You need <protocols> when you (3rd SOURCE keyword) have to exchange information with other people/computers. The <language> is one of above protocols. (4th SOURCE keyword) [@#$] (Don't write these squared brackets in real file) Hypertext Notes --------------- network (1st TARGET keyword) With Network word we intend here a Telecommunication Network. Also called <VAN>. [@@@] (Don't write these squared brackets in real file) supercenters A Supercenter has clusters of processors, hundreds of disk devices. For this reason we use to call them Supercenter. [@@@] (Don't write these squared brackets in real file) protocols See <protocol> [@@@] (Don't write these squared brackets in real file) language Usually in Information Technology we use to call language a source high levelgroup of rules to be translated in machine sequence of binary symbols. [@@@] (Don't write these squared brackets in real file) VAN It stands for Value Added Network. Differs from carrier because of some addedfeatures like a protocol conversion, etc. [@@@] (Don't write these squared brackets in real file) protocol It's a group of rules to let participants to understand each other. ---end of file----- (don't insert this line in your file) We have declared network as the first SOURCE keyword. We've enclosed thisword between decimal 60 character (as in CONFIG.SYS in SKD_LFT parameter) anddecimal 62 character (as in SKD_RGT). Now we have to put somewhere thecorresponding TARGET keyword. You can change in CONFIG.SYS these delimitingcharacters. *************************************************** For each SOURCE keyword a TARGET keyword MUST exist *************************************************** In #_PLUTO.UPD example we've put at documents end a new document called"Hypertext Notes" where we can write all Hypertext TARGET keywords andrelated texts. We have here to declare first TARGET text (in this case the word "network")and we have to enclose it between a "" decimal 17 (as in VISION.CFG in theTKD_LFT parameter) and a "" decimal 16 (as in TKD_RGT parameter). Obviouslyyou can change these two characters in VISION.CFG. After TARGET keyword declaration we have to write below an explanation ofthis keyword with following limits : no more than 78 characters per line. ********************************************* KEYWORD WINDOW limit is 78 characters x lines ********************************************* After text end write three "@@@" (as in VISION.CFG in WDW_END parameter) tolet VISION understand where text stops. **************************************************** DON'T insert the break-string at the END of the file **************************************************** Attention to break-string ------------------------- When you are using HyperText capability, pay attention to the break-stringcharacters of HyperText texts (usually three "@@@", decimal 64, declared inVISION.CFG in the WDW_END=xxx option), different from the break-stringcharacters for VISION texts (they MUST be ALWAYS "@#$", dec 64, dec 35 anddec 36). You have the option to change the HyperText break-string to get moreflexibility in designing you HyperText structure. In fact in the "glossarydocument" case you need to have each VISION text be at the same time anHyperText text too. In this case, declare the same VISION break-string (thus"@#$") in WDW_END=xxx parameter in VISION.CFG file, for HyperText break-characters. **************************************************************** Every time you're building a new doc with HyperText function VERIFY the break-string value on VISION.CFG in WDW_END parameter **************************************************************** How VISION looks for keywords ============================= When VIS_CRE program founds a keyword, before saving it to filename.KEY file,it removes both leading and trailing blanks, embedded blanks and convert itinto an UPPERCASE string. Thus the keyword "pippo" or "Pippo" is converted to"PIPPO". The keyword "Pippo is beautiful" to "PIPPOISBEAUTIFUL". VISION Command Line =================== You can execute VISION also from another program capable to SHELL to DOS. To do that you have only to execute VISION in command line mode, thusVISION.EXE followed by data base name: C:\VISION\VISION #_pippo Changing Text Font ================== If you have a VGA monitor, you can change the ROM standard PC font. You haveto execute before VISION a small utility VIS_FONT which loads a modern-d font(use firstly VIS_FONT /D option) into PC ROM. You can change the font using instead of /d the /s "scrawled" hand made font,or /l or no option for modern-s font. PC Configuration ================ You need any MS-DOS compatible Personal Computer with : - at least 256 k Bytes of main memory - hard disk - video better if : - 640 K bytes of main memory - VGA color video History ======= 4.1 - Added VIS_UPD.EXE to revert VISION Data Bases into the original ASCII .UPD file. - Fixed a bug while printing documents from a very large Data base. 4.2 - Fixed minor bug in main menu window when DBs are exactly 14 files. 4.4 - 15 Data Base names on Main Menu instead of 14. 20 text rows on Text Windows instead of previous 19. - No more RAM option. - No more SOUND option. - Added Data Base name SORT option. - Slightly faster than 4.2 version. 5.1 - Partially rewritten and recompiled used P.D.Q library to have a complete assembler code. Much smaller than before and faster. - Added Hypertext Capability. - Removed Alt-D shell to DOS. - Added Alt-B to create new DB directly from Main Menu. - Added Alt-E to edit source ASCII .UPD file. - Added Alt-U to rebuild original source .UPD file. - Added Alt-D to erase a DB from Main Menu. - Each of four layers has each Help screen. 5.5 - fixed a bug in Command Line option. - Alt-P and Alt-F in a Keyword Window print also first line. - no limit in a Keyword Window. Text can be of any length. 6.0 - Text Data Base with variable record length - Added TAB, Shift-TAB and Shift-Home commands to scroll text left and right (variable line length). - Revised VISION doc with added Hypertext features 6.1 - Fixed a bug in Title section. Extraneous text after an F10 type string search in some circumstances. - Keywords are searched without taking care also of embedded blanks (leading and trailing blanks were not taken into account in previous versions) 6.2 - Added compression option (using LHA) - Cosmetics to VIS_CRE and VIS_UPD - 16 titles instead of 15 in Main Menu - Fixed a bug using VISION.DIR option and SORT=BYNAME HyperText Notes =============== Hyper Text An Hyper Text is a text in which each word can be a keyword to access another text via a Keyword Window, opening new text paths, adapting thedocument reading to the specific <reader knowledge>. Once in a new path (orin a new <Keyword Window> ) you can find there another keyword to accessanother keyword window so that you can <navigate> your text as you like, orbetter as it's required by the level of your knowledge, following differenttext paths. You can have as keyword even an IMAGE or a PROGRAM so that your text couldbecome a media not only to inform readers but also to teach them lessonsexecuting demo programs etc. VISION has text keywords only. To declare a word be a keyword,enclose it between two <character delimiters>. @@@ keyword In an Hypertext each word can be a keyword, thus pressing the ENTER key onthis highlighted word, you can enter in a new text path, opening a new<keyword window>. @@@ keywords See <keyword> @@@ character delimiters See <Character Delimiter> @@@ Character Delimiter VISION must know the hot keyword you want to investigate. It's enough todelimit the word or the phrase with two characters, the first one is thestarting and the second one the ending character. You can use the character you want (declare them in the VISION.CFG file) i.e.brackets, parenthesis,etc. but you must be careful to don't declarecharacters you use currently as text. You can also use the character set from DECIMAL 1 to DECIMAL 31 (unprintablecharacters) being careful on some special characters like DECIMAL 26 (end offile). Try first DECIMAL 16 (starting) and DECIMAL 17 (ending) or DECIMAL 4and 5. @@@ Source Keyword The source keyword is the word which opens a new text path opening a new<Keyword Window>. @@@ Target Keyword The TARGET keyword is the corresponding <Source Keyword> word with itsexplanation. In this opened new window, other keyword can exist. @@@ Keyword Window You can mainly use this kind of keyword to immediately open a Pop Up Windowon the Source Keyword, useful in HELP files. VISION looks for a keyword delimited <character delimiters>, reads all thelines up to ending mark (i.e. "@@@") and displays related text in a window of78 characters x 20 lines. A Keyword Window can have one or more keywords opening other Keyword Windowsup to a maximum of 16 nested windows. @@@ navigate See <Navigation> @@@ navigating See <Navigation>. @@@ Navigation You can navigate an <Hyper Text> in the following way : - Home key go to document beginning - End key go to document end - PgDn/PgUp one screen page Down or Up (21 rows) - Arrow Dn/Up one line Down or Up - Arrow Left/Right change keywords (if they exist) - ENTER key open a new <Keyword Window> - ESCape key come back to previous help window or main text @@@ reader knowledge Current media force people to adapt themselves to them, having available onlya YES-or-NOT option. If you want to read a newspaper article you have to readeverything or nothing, if you're listening to a television speaker you haveto listen all the speech or to close the TV, the same for movie, theater,book etc. Using Hyper Text document, the reader can decide the level of knowledge hewants, because <navigating> the text he can go where he needs, can come back,navigate again so that at the end he can learn exactly what he wants, nothingmore, nothing less. @@@ network With Network word we intend here a Telecommunication Network. Also called <VAN>. @@@ supercenters A Supercenter has clusters of processors, hundreds of disk devices. For this reason we use to call them Supercenter. @@@ protocols See <protocol> @@@ language Usually in Information Technology we use to call language a source high levelgroup of rules to be translated in machine sequence of binary symbols. @@@ VAN It stands for Value Added Network. Differs from carrier because of some addedfeatures like a protocol conversion, etc. @@@ protocol It's a group of rules to let participants to understand each other. @@@ Free Form Textual Data Base . Free Form because you can build a new Data Base from an existing ASCII, listable file, without any change. . Textual because each DB record is a text line . Data Base because VISION uses DB technique to organize text lines in DB records @@@ directory A DOS directory is a part of the PC non volatile storage (hard disk ordiskette). You can create a directory, enter into this directory or removethe directory. MD = Make Directory (to create a new directory) CD = Change Directory (to enter into a new directory) RD = Remove Directory (to cancel an empty directory @@@ LHA VISION uses LHA version 2.13 July 20,1991 developed by Haruyasu Yoshizaki tocompress and decompress VISION Data Bases. LHA is embedded into VISIONprograms so that you see only "Expanding Data Base.." message while it works. Thank you to Yoshizaki this program, under simple conditions you can readexecuting LHA213.EXE program included in this package and reading LHA213.DOCfile, can be considered Public Domain.
