VISION SYSTEM ================= (v 5.1 01-Oct-1992) by Maurizio Ammannato (R) 1992 Maurizio's House Welcome to VISION System ======================== Vision is a Free Form Textual Data Base System. The first access method is the usual hierarchical Chapter/Pages two-levels access. In this way you can read newspaper articles, documents, books, dictionaries, glossaries, help files ,etc.) just choosing the Data Base you want read (first layer), then its Chapters (second layer), finally the chapter Pages (third layer). Or you can access a VISION Data Base using HypertText technique, thus navigating text through its key-words (fourth layer). This package allow you to build your own Text Data Base by yourself. It isn't not just a "Read Only" package. Licence Fee =========== The package is completely free of charge for personal use. Do as many copies you like for you and your friends. However you don't have to sell it or make any kind of profit. Any commercial use of VISION must be agreed with the Author. MY PREFERRED SENTENCE ===================== "It's hard to believe that good people are still the Silent Engine of the World as it is to believe that under the dirty sea surface a large and clean world really exists. Unfortunately this Appearance bombs constantly our senses; fortunately it is a very small part of the Entire." (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.ZIP file 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) - 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 using the same procedure as before; after that copy all .ZIP files in a back-up device and REMOVE all .ZIP (i.e. "ERASE *.ZIP") to save precious disk space. VISION Configuration ==================== Check through your favorite Text Editor or WP the configuration file VISION.CFG and change what you need or wish to change. Foreground color numbers can range from 1 to 31 (after number 15 the color is blinking). 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 SORT=BYNAME or BYDATE or NO sort option EDITOR=filename full path of your preferred Text Editor (Alt-E) WDW_END=@@@ break-characters for Keyword Windows 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_DBR=10 foreground DBW highlighted DB name B_DBR=1 background DBW highlighted DB 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 color parameters. To make your life easier, if you have a monochrome screen, copy directly VISION.BW to VISION.CFG file using DOS COPY command: C:\VISION\COPY vision.bw vision.cfg VISION.MSG Message file ======================= Edit also VISION.MSG messages file and 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 new comment/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 least one TDB (Textual Data Base) with both .DB and .NDX files. You must at least have VISION files. You can create a new one by yourself (see below) or download some from a BBS. Remember to decompress them if ZIPped as explained before. You have two different ways to execute VISION. 1) MENU MODE. Typing VISION at DOS prompt, you enter into Main Menu Window with the list of available Data Bases (see below): C:\VISION>vision 2) COMMAND LINE MODE. Typing VISION followed by data base name at DOS line prompt, 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 of VISION. 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 VGA followed 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 structure used 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 Bases with related comment, last update data and size. The limit of available TDB is 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 on the line of chosen DB (highlighted color) the ENTER key allow you to open the Title Menu (you enter into 2nd layer). *************************************** ENTER key to OPEN highlighted Data Base *************************************** Initially TDB Titles are indexed sequentially (first record found, first record in DB). You have two possibilities to change the indexing method by pressing ALT-S or ALT-T keys. These two commands tell VISION to sort highlighted 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. To use this option you have to declare before, in VISION.CFG file, the preferred Text Editor FULL PATH and EXTENSION. Then, non depending on which highlighted name you are, press together Alt-E keys and give the filename WITHOUT .UPD extension. If you use an editor called QEDIT, in \EDITORS\ directory on D: device, write in your VISION.CFG the following path: ........................... EDITOR=D:\EDITORS\QEDIT.EXE ........................... ************************************ Alt-E to EDIT source ASCII .UPD file ************************************ From Main Menu you can also directly build a new VISION Data Base. Non depending on which highlighted name you are, press together Alt-B keys and give the New data base name WITHOUT .UPD extension (you must have this ASCII file 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 the bar on the Data Base name then 2) press Alt-U. You are required for confirmation. ****************************************** Alt-U to REBUILD source .UPD file (EXPORT) ****************************************** To delete an existing Data Base, move the bar up to selected Data Base name and press Alt-D keys. Before removing highlighted Data Base, you are required to confirm that. This command DOESN'T cancel the related .UPD source file but only .DB, .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 you need, 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 again using 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. An example. Let imagine you want to search the word "disciple" in the New Testament. 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 search the string within the index comment line (Index level), while F9/F10 keys search 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 related document. ************************************** 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) =============================================== 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 Up/Down arrows, PgUp/PgDown and Home/End keys allow you to quickly navigate across 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 the real book reading. The first one is to mark a position for latter retrieve. Use Alt-M when you want stop reading at a specific position (a soft beep advises you of work done). Once you are back to same document use Alt-J to jump to mark. With no mark, 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 use the Alt-A automatic scroll option. VISION has a default value of 7 seconds delay time between scrolling (see in VISION.CFG the SCROLL_SPEED option) so that you can read it relaxed and quite. Use plus key (+) to slow down scrolling speed or minus (-) key to increase such a speed. Keyword Window =============== Once in the a Keyword Window, press Alt-H keys to get following Help: Help - MAIN Window Available Commands ===================================== -/- Keyword Navigation Alt-H This Help ─┘ Open Keyword ESC Exit Because in a Keyword Window you can find other keywords, use Left/Right arrows to navigate these new keywords. You can have up to 16 Keyword Windows in 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 document has for example 1000 words, you can have at the maximum 1000 keywords for this level. Once open one of these 1000 keyword, you enter FIRST LEVEL Keyword Window where you can find other keywords (in a Keyword Window you can find about a maximum of 100 words). Then you can choice one of them and enter in the SECOND LEVEL Keyword Window, and that up to 16 LEVELS Keyword Windows in depth. If we have for example a Data Base with 100 documents, each document with 1000 words and assume that each of them are a keyword, and each of them opens a FIRST level window with about 100 keywords per window, up to 16 LEVELS in depth, the maximum number of Keywords Windows we can have for that Data Base is the following : 100x1000x100x16=16,000,000 VISION Data Base Technical Structure ==================================== VISION System works using two different files, the index file with .NDX extension and data base file with .DB extension. If Data Base uses also keyword option, VISION creates in this case a third 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 very simple : 1) Comment line (78 bytes 78 characters) But you have to don't care at all of this technical info, you have only to follow 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 a new source file called i.e. #_PIPPO.UPD (the .UPD extension is a MUST) and write 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 document lines with a maximum of 78 characters (pay attention to don't write the following special combination of characters '@#$' at the line beginning). 3) special break-string combination to close the document; that is a '@#$' at the 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 VISION format Data Base ----------------------------------- Once done this ASCII test file, on VISION Main Menu, press Alt-B keys and give its filename without any extension. This file MUST reside in same VISION directory. ****************************************************** .UPD source files MUST be in the same VISION directory ****************************************************** You can also use VIS_CRE program at DOS level without entering VISION Main Menu : C:\VISION\vis_cre #_pippo This program creates #_PIPPO.NDX with three master records (NETWORK,SUPER- CENTER,PROTOCOL) and the #_PIPPO.DB data base with text. After VISION has created these two files, it asks for a DB comment line. (You can also change this comment later, on Main Menu press Alt-C keys on highlighted name). See and use this example to understand how to build or to modify a source ASCII .UPD file. #_PIPPO.UPD must be in the VISION delivery disk or ZIP archivie. *********************************************************** 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 want to transform them in the more readable VISION format. VISION can very easily transform 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 form character, page break, etc.) and do exactly the same procedure as to build a new 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 as before to create new source file so that the original PIPPO.DOC looks like the 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 Main menu 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) exit VISION (ESC key) 5) use your preferred Text Editor to UPDATE source .UPD file 6) enter again VISION 7) Alt-B keys to update VISION Data Base (.DB, .NDX and eventually .KEY) or with Alt-E option : 4) Alt-E to edit .UPD just created source file 5) Alt-B keys to update VISION Data Base (.DB, .NDX and eventually .KEY) Erasing Data Base ================= Enter VISION Main Menu, move bar on Data Base to remove, then press Alt-D keys. 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 three different 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 make any sort. Using SORT=NO and VISION.DIR option, you can decide by yourself the Data Bases 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, VISION sorts automatically them by new alphabetical order putting them in the position 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 get a different classification. For example if you want to put #_PIPPO Data Base in first Main Menu line, execute the following DOS command, at DOS prompt, in the 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 you have 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 at the 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 to VISION.DDD, an example file in the distribution disk. When you load a new data base, remember to update VISION.DIR file otherwise the program will ignore it. ************************************************** REMEMBER to UPDATE VISION.DIR when adding a new DB ************************************************** To Create Hypertext Document ============================ To build document in HyperText 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 to find 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) to which 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 level group 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 added features 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 this word between "<" (decimal 60 as in CONFIG.SYS in SKD_LFT parameter) and ">" (decimal 62 as in SKD_RGT). Now we have to put somewhere the corresponding TARGET keyword. You can change in CONFIG.SYS these delimiting characters. **************************************************** For each SOURCE keyword a TARGET keyword MUST exists **************************************************** In #_PLUTO.UPD example we've put at documents end a new document called "Hypertext Notes" where we can write all Hypertext TARGET keywords and related 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 the TKD_LFT parameter) and a "" decimal 16 (as in TKD_RGT parameter). Obviously you can change these two characters in VISION.CFG. After TARGET keyword declaration we have to write below an explanation of this keyword with following limits : no more than 78 characters per line, no more than 20 lines per comment. *************************************************** KEYWORD WINDOWS limits are 78 characters x 20 lines *************************************************** After text end write three "@@@" (as in VISION.CFG in WDW_END parameter) to let 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-string characters of HyperText texts (usually three "@@@", decimal 64, declared in VISION.CFG in the WDW_END=xxx option), different from the break-string characters for VISION texts (they MUST be ALWAYS "@#$", dec 64, dec 35 and dec 36). You have the option to change the HyperText break-string to get more flexibility in designing you HyperText structure. In fact in the "glossary document" case you need to have each VISION text be at the same time an HyperText text too. In this case, declare the same VISION break-string (thus "@#$") 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 **************************************************************** VISION Commamnd 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, thus VISION.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 have to 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 (the reading is easier) 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. 5.0 - 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.
