THE FINE PRINT SHAREWARE - THE CONCEPT THE SUGGESTED CONTRIBUTION - Pay only once! - Multiple copies TECHNICAL SUPPORT OVERVIEW - Command line switches - Text search - Wild cards - Examples BOOKMARKS THE VIEW SCREEN THE ESC KEY PRINT FUNCTIONS RESETTING THE PRINTER IMPORTANT NOTE AUTOMATIC DETECTION OF FILE FORMATS THE FILE SELECTION MENU CUSTOMIZING VIEW HTML FILES 2COL JETCOL COMPUSERVE ADDRESS INTERNET ADDRESS MORE SHAREWARE ************************************* WHAT IS VIEW? ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ VIEW is a file viewing utility for DOS. ■ It allows you to view and print files in the following formats: - Wordperfect versions 5.0 to 6.1 - Word for Windows versions 1.0 to 6.0 - Word for DOS - Ami Pro - Wordstar - Windows Write files - Windows Notepad files (which use the ANSI character set) - Windows CLP (clipboard) text files - ASCII files - ANSI files (e.g. created under UNIX) - World Wide Web HTML tagged files - Compuserve mail and messages ■ You can see a quick preview of the first part of files. ■ You can print or save all or part of the files viewed. ■ You can print or save to file only those lines containing or omitting specified text. ■ Printing can be done directly via the compressed print routines 2COL and JETCOL (if you have them). These shareware programs by Tony Caine are provided to those who register VIEW. They allow you to print in multiple columns using small but highly legible fonts. Highly recommended! ■ Windows help files can be viewed via a link to an external program HLP2DOC (which is a freeware utility available on many BBS and provided to those who register VIEW). ■ VIEW allows you to search for text strings (both case-sensitive and case-insensitive), including across multiple files. ■ You can also print or convert files to ASCII, including in format suitable for import to word processor, directly from the file selection menu. ■ You can convert between ASCII and ANSI. ■ You can save files in a format suitable for importing into word processors without a hard return at the end of every line. ■ You can convert or print file directly without viewing, using command line switches. ■ You can convert files to or from UNIX and DOS file formats. ■ Has a special scroll mode for visually-impaired users. ■ Together, VIEW and 2COL/JETCOL offer a powerful file printing utility that can be run under a wide variety of DOS and Windows shells and file managers. ■ VIEW can be identified as the file viewer for a wide range of DOS and Windows shells and file managers, including archive display programs. ■ VIEW is ideal as a viewer for e-mail attachments. ■ VIEW can be customized for display color, and also its printing, display and memory features. Note: as shipped VIEW is configured NOT to use the Windows help file translator HLP2DOC. You must have this utility in a directory that is referred to in your PATH statement. The link to HLP2DOC can be enabled by using the configuration program VIEWCFG. THE FINE PRINT ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ The author makes no warranty that the software in this package will work with your particular hardware configuration. You use the programs entirely at your own risk, and the author will not be held liable for any damage caused to your hardware or software through their use, nor for any consequential damages, loss of earnings, or loss of life, limb, health, sanity or personal relationship. Legalities aside, you should not run into difficulties with this software. SHAREWARE - THE CONCEPT ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ These programs are distributed as shareware, AND ARE NOT CRIPPLED!!. Nor do they contain "nag" screens. (Editorial note: I don't support "crippleware" - I want to know EXACTLY what I'm expected to pay for! Crippleware is, in my opinion, like test driving a Mercedes that's been fitted with a lawnmower engine! There, that's said - but each to his own.) You do not have to register as a user, nor are you under any obligation to buy the program(s). However, they are not free, and in the spirit of shareware, you are requested to make a small donation to the author if you find the software in this package useful, and if you continue to use it after an evaluation period of 30 days. This would both fulfill your moral obligation and help ensure the viability of the shareware concept, from which we all benefit. THE SUGGESTED CONTRIBUTION ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ The suggested contribution is $25 US ($30 Canadian, 12 pounds sterling), but less (or more!) would be fine. Pay what you think the software is worth to you. If you pay the recommended amount or more, I will send you a diskette with the latest version plus a selection of other shareware for you to evaluate, including Tony Caine's excellent 2COL and JETCOL utilities and some useful freeware programs. Should you decide to make a contribution, please remit to: Malcolm Drury 11 Adele Crescent Nepean ON K2J 2T7 Canada INTERNET ADDRESS drury@gsc.emr.ca COMPUSERVE ADDRESS 70574,3457 Bank notes in your local currency would be fine, as would international money orders made out in US or Canadian dollars. Thank you. Please tell me where you got the software from and, most importantly, which version it is. Note to Compuserve members: you can register online. GO SWREG and look for VWFILE.ZIP - Pay only once! ============== IF YOU HAVE PREVIOUSLY PAID FOR AN EARLIER VERSION - THANKS, AND OF COURSE YOU ARE NOT EXPECTED TO PAY AGAIN. YOUR INPUT, COMMENTS ETC. ARE ALWAYS WELCOME. - Multiple copies =============== Please contact me if you would like to negotiate a price for multiple copies. I accept purchase orders, but cannot accept credit card orders. TECHNICAL SUPPORT ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ Please note that at the low contribution requested, I cannot provide DIRECT technical support, nor automatically send upgrades, should they become available. If you have comments, questions, bug reports etc., please leave a message at my Compuserve or INTERNET address, or write to me via snail mail. I will endeavor to fix any problems you might encounter. Users who have paid may, of course, download future upgrades free of charge. I will never post a deliberately crippled version of VIEW, nor a version that has any kind of "nag" message. I also guarantee to honor the suggested contribution for the version of VIEW you are registering in the event that the contribution requested has increased for the current version; you will also receive the current version. I hope my pricing policy will compensate for the lack of direct technical support and mailing of upgrades. The software is supplied on an "as is" basis. You are free to distribute this software package provided that you distribute the ENTIRE package, including this documentation file. (This is necessary for others to be able to use it properly. I've downloaded too many shareware packages that had been posted without accompanying documentation!). I hope you find this package useful. Now to the fun stuff! ****************************************************** OVERVIEW ▌ ▄▄▄▄▄▄▄▄▄▌ Usage: view [d:][path][filename] [/sw1] [/sw2] [/sw3] [/sw4] [text string to find] where switches /sw1, /sw2, /sw3 and /sw4 can be: /a /b /cfilename.cnv /Cfilename.cnv /fxx /h /lnnn /mnnn /mono /q /s /u /v /w /6 /- (in which nnn is a three digit number and xx is a two-digit number) /a - assume the file uses the ANSI (Windows) or UNIX character sets and convert high-order characters (e.g. Ç,é,Ü) to the ASCII set used by DOS /b - allows you to break out of the file read even if you have configured VIEW to disable this function normally. /cfilename.cnv - convert selected file to filename.cnv directly, i.e. without viewing it. NOTE: NOT APPLICABLE FOR WORD 6 FILES. /Cfilename.cnv - as for /c but file is saved in format suitable for import into word processor (i.e. with hard returns within text suppressed) NOTE: NOT APPLICABLE FOR WORD 6 FILES. /fxx - allow the file list to display xx 100s of files. /h - force HTML files to be displayed as ASCII, thus showing their HTML tags. /s - forces VIEW to look for case-sensitive string when a text string is entered on the command line. Without the switch the search is case-insensitive - i.e., if VIEW is told to find string from the command line, it will look for string String STrinG etc. With ths switch used, it will only look for string /lnnn - set line wrap to nnn columns /mnnn - set aside nnn memory allocation units (see below) /mono - force VIEW to display in monochrome /q - preview mode; show only the first screen's worth of a file /u - convert the file to the UNIX format (using the UNIX character and saving the converted file with only line feeds rather than the combination carriage return/line feed used by DOS /vnnnn - overrides the default scroll rate. See file visual.doc /w - convert the file's character set to Windows (ANSI) and save the converted file in the DOS format (i.e. combination carriage return/line feed) /6 - tells VIEW to try a different approach to decoding Word 6 files that appear not to be decoded correctly. /- - allows "strikeout" text in Wordperfect documents to be shown (in UPPER CASE characters). By default, VIEW omits this text. NOTE 1: the /u, /a and /w switches are only meaningful when used with the /c or /C switches, i.e. for converting files directly. NOTE 2: the order of the switches is unimportant. However, any text added for the text search function of VIEW MUST follow th switches. NOTE 3: if you use any of the switches, you MUST include at least a drive letter on the command line. If not VIEW will tell you something like "can't find /m056". NOTE 4: if you are using VIEW from a batch file, such as for converting files directly, you can use the ERRORLEVEL function. VIEW returns error level 1 if for some reason the file cannot be viewed or converted (e.g. file does not exist, unrecognized format). If you just type VIEW you will get a list of files on the current drive and directory, from which you can select the one to view. Similarly, if you type VIEW plus drive and directory parameters, you'll get a list of files on that drive and directory. From the file selection menu, you can change to any directory on the drive, or to any other drive. Note that VIEW supports the * wild card character. - More information on command line switches =========================================== /q == Use this switch for displaying only the first screen's worth of of a file (usually the first 23 lines) in a quick preview mode. This function can be toggled on and off from the file selection menu by pressing the q key. /mnnn ===== If you include the switch /mnnn you will be able to allocate more memory for use by JETCOL, 2COL or HLP2DOC (see below). The more memory you allocate for these programs the less is available to VIEW for loading files. If you only use JETCOL, 2COL or HLP2DOC occasionally you should leave the memory allocation at the default level and use the /mnnn switch when you do want to use them. If you use them frequently, you should probably permanently allocate sufficient memory using the configuration program VIEWCFG.COM. See later in this information file for more information on running JETCOL and 2COL. /lnnn ===== If you use the /lnnn switch the line wrap is set at a maximum of 132 columns and a minimum of 20. The number of columns you want is determine by "nnn" which MUST be a three digit number (e.g. 070, 120). In this mode you can use the left and right arrow keys to scroll the display to the left and right. This mode is useful if you want to print files for which the line wrap is greater than 80 - for instance, program listings. Note that VIEW will also run in true 132 mode (i.e. 132 columns actually displayed on screen if you have a video adapter that allows that mode). (NOTE: when you use the /lnnn switch, the help line at the bottom of the screen will refer to "Cursor arrows". When it is not used the left and right arrow function are disabled and the help line refers to "Up and down arrows"). /c == To convert a file directly, use the /c switch - that is, /c followed immediately by the name of the CONVERTED file. For example, to write a converted file called myfile.cnv the format of the switch would be /cmyfile.cnv The name of the converted file can include a full path (drive and directory plus sub-directory) if you wish, or it could be an alternate printer port. TO PRINT A FILE DIRECTLY use /clpt1 (or /clpt2 etc) /C == This is the same as the /c switch EXCEPT that the converted file is written in a format suitable for import into a word processor. Hard returns within paragraphs are suppressed so that in your word processor you can change the word wrap parameter. VIEW attempts to retain legitimate hard returns. No other formatting is saved. /a ===== This switch causes VIEW to convert high-order characters in a file that uses the ANSI character set (e.g. Windows Notepad) to ASCII. Used only with /c or /C /u ===== This switch causes VIEW to convert high-order characters in a file that uses the ASCII character set to the UNIX character set. Used only with /c or /C. The saved file is in the UNIX file format. /w ===== This switch causes VIEW to convert high-order characters in a file that uses the ASCII character set to the Windows character set. Used only with /c or /C. The saved file is in the DOS file format (used by Windows). /fxx ==== Enable xx 100s of files to be listed in the file list. For example, /f06 enables a display of 600 files. The default is 500 files. The maximum is 1000 (although you can request a special version with up to 3000 when you register VIEW). The more files you enable the less memory is available for actually viewing files, although the loss by going from the default of 500 to, say, 800, is not great. - Text search ============ The text string to find MUST come after the filename, and after any switches used. It allows you to search for the string in all files viewer until the "text search" function is switched off (see later). Text entered from the command line is assumed to be case-insensitive. - Wild cards ========== You can use the * wild-card character in a file name. Then you will get a list of files in the default or specified directory that match the * criteria. Any string identified on the command line for the text search function will be active for all files specified by the wild card option (unless it is changed or switched off when viewing one of the files). - Examples ======== view *.doc - list of files with extension doc in the current directory view d:\docs - list of all files on drive d, directory docs view d:\docs\*.txt - as above, but only files with extension txt view myfile.doc this is a string - open myfile doc and search for "this is my string" view myfile.doc /m060 - open file myfile.doc after allocating 60 block of memory for use by JETCOL, 2COL or HLP2DOC view d: /m050 - list all files on root directory of drive d: after allocating extra memory. view *.txt /l132 - list all matching files and display them in emulated 132 column mode. view myfile.doc /l120 /clpt1 - print the file myfile.doc directly, using 120 column word wrap. view another.doc /cnew.doc - convert "another.doc" and save converted file as "new.doc" view this.doc /u /Csaved.doc - convert "this.doc" to file "saved.doc" which is saved in the UNIX format and with the UNIX character set. view d:\docs\*.doc another string - list all matching files, and as each is opened look for "another string". This search is in effect for all subsequent files until it is switched off. view d:\docs\*.doc /l120 yet another string - display all matching files in emulated 120 column mode, and look for the string "yet another string". Note on text search: VIEW will only find matches in complete lines, i.e. it will not find text that has wrapped. For example, if the text to find is "cat sat on the mat" it would find the following: One fine day the cat sat on the mat and ate a rat. but not: One fine day, the cat sat on the mat and ate a rat. Note that VIEW reads as much of a file as possible into memory, but if not all of a file can be read in it won't display the full file. This allows you to skip instantly to any part of the file in memory without disk reads. If you are not using DOS 5.0 or later, or a memory manager such as QEMM386 or 386MAX, I strongly recommend you do so. If a file is too big, an overflow file is created; you can switch quickly between the two. The overflow should, in most circumstances, allow you to see all of the original file, unless it is really big. If the file IS really big, you can convert it to ASCII (from the file selection menu) and then split it into smaller components using a text editor. When you convert to ASCII from the file selection menu the entire file is converted even if it is too big to view via VIEW. VIEW will automatically detect WordPerfect 5.0 and later, Microsoft Word, Ami Pro and Windows WRITE formats. It attempts to detect other files that may not be ASCII and gives you the opportunity to display them as straight ASCII, as Wordstar - i.e. with the high-order characters stripped out, or in preview mode, or in preview mode. It will automatically force to ASCII certain standard types of non-ASCII file (e.g. EXE, COM, DLL etc.). Using VIEW is pretty straightforward. Pressing F1 brings up a help menu, and the key features of the menu are permanently displayed on the bottom line. Every feature is accessible directly from the view screen, or from the menu screen. BOOKMARKS ▌ ▄▄▄▄▄▄▄▄▄▄▄▌ VIEW allows you to place up to 200 bookmarks in the text you are viewing. This allows you to move quickly to preset places in the text that you have chosen. In addition, when reading in an ASCII file, VIEW assigns a bookmark to any form feed character it finds. The form feeds are not actually displayed, but by setting a bookmark you can move quickly to any place in the text where they occur. See the following section for a description of the keys assigned to bookmark functions (they are: Ins, the grey + key, the grey - key). THE VIEW SCREEN ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ The keys: Navigate through the file using the cursor keys (up and down arrows, left and right arrows if in "wide screen" mode, PgUp, PgDn, Home, End). Ins - insert a bookmark immediately following the line of text at the top of the display. Note that when used with the Shift-F9 print function bookmarks act as form feeds. Thus to set a form feed after line 48, for example, scroll the display until line 48 is the first line of text, then press Ins. Grey + key - go to the next bookmark. If you are at the last one, this key moves to the first one (that is, cycles through the bookmarks). First, though, it repeats the bookmark you are currently at in order to indicate that you are at the last one. Grey - key - go to the previous bookmark. If you are at the first one, this key moves to the last one (that is, cycles through the bookmarks). First, though, it repeats the bookmark you are currently at in order to indicate that you are at the first one. Enter - find text currently displayed at the top of the display area. Use this function for going directly to topics listed in the contents. NOTE: The Enter key is a toggle. Press it a second time to return to the point at which it was first pressed. h - toggle between displaying HTML files with codes stripped and with codes shown. s, Alt-F9 - toggle speaker "beep" on/off (beeps when an illegal key press is made). w, Alt-F10 - toggle word wrap on/off (plain text files only). x - toggle between displaying XYWRITE files with codes stripped and with codes shown. F1 - help menu; all menu items are available directly from this menu (i.e., while the menu is displayed, pressing F2 will activate the appropriate function for that key). F2 - case-INSENSITIVE text search - matching text is shown in the highlight color. Unless the string to find has been defined from the command line, the first time you press F2 the string is defined. Subsequent presses of F2 find the next occurrence. F3 - as for F2, but for case-SENSITIVE text. Shift F2 - toggle text search OFF. (NOTE: when the text search function is enabled an asterisk (*) appears at the bottom right corner of the screen.) F4 - enter scroll mode for use with voice synthesizers. For details, see the file visual.doc F5 - go to a particular bookmark number Shift F5 - go to a particular line number F6 - print all of file to printer or disk Shift F6 - set or reset HP and HP compatible printers that use the PCL4 command set (portrait or landscape mode, normal or compressed print). This includes a user-definable command. F7 - print all lines that specifically include or exclude a particular text string F8 - print file currently being viewed directly via 2COL or JETCOL. NOTE: you must have either configured VIEW to reserve at least 55 memory blocks, or you must use the switch /m055 on the command line, to activate this feature. Shift F8 - clear all bookmarks F9 - this is a toggle for printing (to printer or disk) a block of text. The first time you press F9, the current top line is set as the beginning of the block. The second time, the current top line is set as the end of the block, and the block is printed to the location you specify. While block select is on, you will see a message at the bottom-left of the screen telling you the starting line of the block. Shift-F9 - allows you to print a document with embedded form feeds retained, or with inserted bookmarks interpreted as form feeds. With this function the default page break is ignored, and you can also override the default left margin indentation. F10 - changes the character set of the file being displayed from ANSI to ASCII. If you print to file after this conversion is made, the file you print will use the converted (i.e. ASCII) character set. This feature is useful for converting Windows NOTEPAD files and others created with the ANSI set (e.g. text files created under UNIX). Shift F10- changes the character set of the file being displayed from ASCII to ANSI. As with F10, files printed to disk will contain the ANSI character set. Space bar- leave menu without enabling any of the features. If you have read in a large file that has resulted in a temporary overflow file being created, the following keys are also activated: n - move to overflow file ("n" means "next") p - move to original file ("p" means "previous") If you hear a "beep" the function is not currently activated (e.g. already in that file, or you have blocked off text but not yet printed it). When in "overflow" mode an identifying letter appears at the bottom-left of the display. "p" means you are in the second level, i.e. overflow file, and "n" means you are in the top level, i.e. original file. Note that in the second level, you will be told that the file is ASCII, and called overflow.1. Not to worry: it still contains the overflow from the file you called to read. Pressing the letter takes you to the <p>revious or <n>ext part of the file. THE ESC KEY ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▌ You can use the Esc key while a file is being converted directly from the file selection menu or is being printed interrupt the process and exit to DOS. This does not affect a file being loaded normally. PRINT FUNCTIONS ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ Note: for the print functions, you have the following choices: - print to printer - save to file (and you can also use this for printing to an alternate printer port - just use the port name as the name of the file to be saved) - print directly via 2COL or JETCOL - save file in format suitable for importing into word processor (as far as possible VIEW puts hard returns where they are needed and omits them where they are not). F6 - F9 allow you to print to file, to printer, or via 2COL/JETCOL. The latter function produces a file called cainelnk.fil, which is deleted when processing has finished. If you have not set aside memory for 2COL/JETCOL (see configuration, VIEWCFG) you can simply write a file (converted to ASCII) to disk and process it separately with 2COL or JETCOL. Alternatively, you can load VIEW with the /mnnn command to allow to to allocate (temporarily) enough memory to run 2COL or JETCOL. F6 print or convert file. You can include line numbers if you wish. You can interrupt this process by pressing the Esc key. F7 print only those lines containing or omitting a text string you define. F8 Allows you to access JETCOL or 2COL directly (assuming you have them of course!) to print the entire file. Pressing F8 allows you to enter a command line for JETCOL or 2COL, thereby allowing you to set switches individually. You should NOT enter a file name - VIEW does this for you, as it uses a special ASCII file. The true file name will be added to the end of the printout. If JETCOL or 2COL do not exist in a directory that your PATH statement specifies, you must include the full path in your command line. Example: c:\jetcol\jetcol -W70 - prints the file using JETCOL, which is in directory c:\jetcol; the single W switch is activated. If when you try to print via JETCOL or 2COL nothing happens except that the display returns immediately to VIEW, one of two things is the probable culprit. Either JETCOL/2COL has not been found, or you have not set aside enough memory for VIEW to link to JETCOL/2COL. For the former, check that you entered the path properly. For the latter, reconfigure VIEW using VIEWCFG.COM and set aside 50 or so "memory blocks" (the configuration program will tell you when to do this), or load VIEW with the /mnnn command. F9 This key is a toggle to allow you to select a block of text for printing. The first time you press it the block starts at the line currently at the top of the display; the second time the line at the top is the end of the block. Once selected, the block can be printed as for the F6 key. RESETTING THE PRINTER ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ (For HP compatible printers and those that use commands beginning with the Esc character) In VIEW 10.0 the "reset printer" function has been moved to a separate file, HPSET.COM This can be called as before by pressing Shift-F6. It can also be used as a standalone. Usage is: hpset - reset printer on default port (lpt1) hpset port - reset printer on port "port" Note: if you wish to use this function from within VIEW you must set aside enough memory allocation units - it needs at least 35. This can be done permanently through VIEWCFG.COM, the customization program, or temporarily by using the /m035 switch. IMPORTANT NOTE ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ If you are viewing anything other than a straight ASCII or ANSI file, it will not look the same as the version that you print from the word processing software. If the document uses a proportional font, or contains columns or tables, the appearance under VIEW will in all probability be different. This is because of the way VIEW simplifies the formatting built into such documents. If VIEW were to be designed to show all formatting faithfully, it would be at least as big as the executable files used by the word processors themselves and would therefore lose its point as a quick viewer. I have attempted to cover all formatting and embedded code possibilities, but with the power of WordPerfect, Word and Ami Pro, the possibilities are mind-boggling! If you come across a file that does not seem to display properly - e.g. hangs mid-way through or displays garbage - please send it to me and I will attempt to fix the problem. NOTE: VIEW will NOT properly display Word 6 files saved with the "quick format" feature. Such files are extremely complex and I have so far been unable to develop an algorithm to handle them. Note that Wordstar files may contain some extraneous characters, including "dot commands" such as .PA - however, they should certainly be readable. AUTOMATIC DETECTION OF FILE FORMATS ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ VIEW will automatically detect Word, Ami Pro, Windows Write, WordPerfect, Windows clipboard (CLP), Windows help files and ASCII files. For others, it may tell you that the format is unknown, and give you some options: ┌──────────────────────────────────────────────────────────────────────────┐ │ Undetermined file format - please select display option: │ │ F1 show as ASCII F2 - preview F3 don't view │ └──────────────────────────────────────────────────────────────────────────┘ F1 - means show the file as if it were a true ASCII file. VIEW will automatically assign certain types of file (e.g. EXE, COM, BIN, DLL) to this display mode. F2 - means show the file with high-order characters omitted. Useful for scanning for text strings and previewing files of unknown format. F3 - means don't try to show the file. If you choose F1, you will be asked which line wrap you want - that coded directly into the file, or the VIEW default. You should choose the former first, as it will be appropriate for files with fewer than 80 characters per line. If the file has more than 80 characters per line, however, this display will cause lines to break within words. In that case, try choosing VIEW's defaults. Just go with whichever suits you! THE FILE SELECTION MENU ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ If you have called VIEW without specifying a particular file, you have access to the file selection menu, which looks like this:- C:\VIEW\*.* - 9 item(s) (0 read) Keys: Ctrl-Home Ctrl-End PgDn PgUp Home Enter Esc - exit F1 - help ASCII line wrap OFF ┌───────────────────────────────────────────────────────────────────────┐ │ .. │ │ file_id.diz │ │ new121.doc │ │ trouble.doc │ │ view.exe │ │ view121.doc │ │ viewcfg.com │ | | │ │ └───────────────────────────────────────────────────────────────────────┘ ┌───────────────────────────────────────────────────────────────────────────┐ │UPPER CASE - directories lower case - files q - toggle quick view mode │ │F2 - set line wrap F3 - toggle ASCII line wrap on/off F4 - Wordstar │ │F5 - preview mode F6 - convert/print F7 - new drive F10 - ANSI on/off │ └───────────────────────────────────────────────────────────────────────────┘ THE KEYS: Use the arrow and cursor keys to scroll through the list of files, and press Enter to view the highlighted file or to change to the highlighted directory. Ctrl-Home - goes to first file in the list. (Use Home if you are at the first screen). Home - goes to the firat file in the current screen. Ctrl-End - goes to the last file in the list. End - goes to the last file in the current screen. F1 - brings up a help menu F2 - allows you to change the column at which lines wrap. F3 - toggles line wrap on and off. When toggled OFF, line wrap occurs according to the file's setting and ignores VIEW's setting. In this mode, lines in ASCII and Wordstar files may wrap within words. When toggled ON VIEW prevents (as far as possible) breaks appearing within words. You can use this feature to reformat ASCII files; for example, to change the width of lines. NOTE: line wrap toggle is only used for ASCII or pseudo-ASCII (e.g. Wordstar) files. It has no effect on WordPerfect, Word etc. files. F4 - tells VIEW to treat the file as Wordstar. F5 - tells VIEW to treat the file as "unknown format". High-order characters are stripped out and error trapping routines are initiated during the file read (e.g. missing end-of-file) F6 - allows you to convert a file to ASCII or print it directly without viewing it, including via 2COL/JETCOL. You can interrupt this process by pressing the Esc key. Shift F6 - allows you to reset HP and HP-compatible printer mode for those printers that recognize the PCL4 command set. F7 - allows you to change to another drive. A list of available drives is displayed. Just type in the drive letter you want and press "Return". Note: this function default the file listing parameter to *.*, i.e. it results in all files on the drive and directory shown being listed. F10- the next file to be viewed will have its character set converted from assumed ANSI (e.g. Windows NOTEPAD) to ASCII. F10 is a toggle - press it a second time and this feature is switched off. s - toggles the speaker "beep" on/off (beeps when an illegal key press is made). q - toggles quick view mode on/off. When on, a Q appears above and to the right of the file list. (Also Alt-F8) z - tells you how many display lines are available and how many 2000 byte memory blocks you have set aside. Esc- exit to DOS CUSTOMIZING VIEW ▌ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▌ VIEWCFG usage: viewcfg [filename] where filename is view.exe or an exact copy with some other file name. If the wrong version of VIEW is found, VIEWCFG will tell you so. This program allows you to customize VIEW.EXE. Setting colors is self-explanatory. However, VIEWCFG also allows you to set some print parameters, such as number of lines per printed page, number of spaces to expand tabs, and number of spaces to leave for the left margin. After setting colors, VIEWCFG allows you to override the default number of lines of display and display speeds. VIEW as shipped is configured for normal display speed and hard coded to display 25 lines by 80 columns. Try experimenting with the display parameters to get maximum benefit; if your system crashes - and there's a lot of non-standard hardware and BIOS software out there - just reconfigure VIEW to a lower display standard. Next, you to choose whether the "delete file?" feature of VIEW is activated. As a safety measure, you may wish to set this to "off". Even with the feature on, a file will not be deleted until you have answered an "are you sure?" question. Protected (read-only) files cannot be deleted directly from VIEW. You can also configure some display and print parameters - the number of lines per printed page, the default printer port, and the offset from the left margin or printed output. VIEWCFG allows you to set the column at which lines wrap. The default is 66 - that is, VIEW counts characters per line and if it is within 14 of the rightmost screen column puts in a line feed if it finds a space. This is not absolutely foolproof; you may find that setting the line wrap column to less than 66 gives better performance. (NOTE: you can temporarily over-ride the default setting from the file selection menu). Next, VIEWCFG allows you to change the default number of files that can be read in sequence from the file selection menu. Each time you read a file a small amount of memory is lost to the system (until you exit to DOS, when it is fully restored). To prevent memory allocation errors VIEW exits to DOS after a certain number of files have been read. The default is 50. If you wish to experiment with a higher number, you can do so via VIEWCFG. Don't go above 100. If you find that your setting does cause a system freeze, just reduce the number. There is no "best" value - it depends on the amount of free RAM on your system, the nature and operations of any TSRs or memory managers you have running, etc. You should have no problems going with the default of 50. Next, VIEWCFG allows you to reserve some memory for use by 2COL or JETCOL. When it loads, VIEW uses all available conventional memory for displaying files, in 80 column lines. You must set aside memory for 2COL or JETCOL, in 2000 byte blocks, equivalent to 25 lines of file. There is a trade-off - the more memory you set aside for 2COL/JETCOL, the fewer the lines before getting a "file too big" message. Currently, 2COL and JETCOL require you to reserve about 50 blocks; if you don't want direct access to them you can reduce this. However, VIEW itself needs some memory in reserve. When asked to enter a number of 2000 byte blocks, you should enter at least 10, and probably 13 or 14, and at least 48 for access to 2COL and JETCOL. You may need to experiment a little to find the minimum number of memory blocks you need to allocate, as this will depend to some extent on how much conventional memory your computer has available. PLEASE READ THE ACCOMPANYING FILE "TROUBLE.DOC" FOR MORE INFORMATION ON THIS TOPIC. Finally, you can specify the default number of files, in 100s, that can be displayed in the file list. The maximum is 700 (for which you would enter 7 i.e. 7 x 100). Registered users can request a higher number. SUGGESTION: Configure two versions of VIEW, one with and one without 2COL/JETCOL access. HTML FILES ▌ ▄▄▄▄▄▄▄▄▄▄▄▌ VIEW displays HTML files that have been prepared to the HTML 2.0 standard. It will display, but not properly format, tables. It can also be used as a basic syntax checker. It will write information on any missing > or ; tags it comes across to a file c:\htmlerr.rpt. It fills in missing tags, but this means that some ext may be missing. VIEW will automatically decode HTML files PROVIDED the first character in them is <. Otherwise, it assumes they are ASCII. You can force it to display the tags in HTML files by using the /h command line switch or pressing Shift-F3 at the file selection menu.

I post it as ZIP files, but it may also appear as ARJ (or other format) files if re-posted by others. VGAPAL40.ZIP - customize up to 4 VGA text color palettes, choosing from more than 250,000 colors! (And see how many you can actually discern!). One palette can be used to create a small (2k) TSR program that maintains your chosen scheme. Alternatively, you can set any of the palettes, or a grey-scale scheme, from a non-TSR if memory is a problem. (On CIS Ziffnet as vgacus.zip in ZNT:TIPS). BBS SEARCH: VGAPAL??.* DDIR130.ZIP - double-column directory display that highlights new files, flags system, hidden and read-only files, and optionally shows the "dead" space on disk associated with each file or the total space each file actually uses. Full file list sorting, and can scroll back and forth within the file list. Has file delete and protect/unprotect functions. Links to VIEW, LIST and VPIC. Also archive/unarchive files via links to PKZIP/PKUNZIP, ARJ, LHA, SQZ and ZOO. Will also automatically decode UUENCODED files. (On Compuserve Ziffnet as dirdpy.zip in forum ZNT:TIPS) BBS search: DDIR??.* DSPAC65A.ZIP - shows graphically hard disk space installed, used and free, for all drives; second program shows graphically space on designated drive (including floppy), and reports on installed and available RAM, including XMS and EMS memory. (On CIS Ziffnet as dskspc.zip, in ZNT:TIPS). BBS SEARCH: DSPACE??.* IF YOU DO NOT FIND ANY OF THESE, SEND ME A MESSAGE! USERS WHO REGISTER VIEW WILL RECEIVE THESE (OR THE LATEST VERSIONS). You can also search your favorite BBS for 2COL and JETCOL.
