┌────────────────────────────────────────────────────────────────┐ │ │ │ │ │ │ │ │ │ AUTOREAD │ │ │ │ A program to allow easy reading of large text files │ │ on a computer │ │ │ │ Author: David R Grigg │ │ │ │ Version 1: │ │ June 1990. │ │ │ │ │ │ │ │ MANUAL │ │ │ │ │ │ │ └────────────────────────────────────────────────────────────────┘ 1: IMPORTANT NOTICE! ═══════════════════════════════════════════════════════════════════════ If you are reading this file on your computer in any other way than using AUTOREAD itself, then you are losing out on the value of AUTOREAD, and you will also not be able to try out the software as you follow the examples given later in this document. To read this document using AUTOREAD, go back to DOS and type: AUTOREAD MANUAL.DOC <and press the enter key>. DISCLAIMER ══════════ While every effort has been made to free AUTOREAD from errors, NO RESPONSIBILITY IS ACCEPTED for any damage that may be caused to your computer, disks or data by the use of AUTOREAD. If this makes you nervous, try AUTOREAD out on a floppy disk first. 2: Introduction ════════════════════════════════════════════════════════════════════════ I wrote this program because I often find myself in the situation of having a large text file on my computer's hard disk which I am using because it has some kind of information of value to me. Usually it is the manual for a shareware program. I adore shareware. I think the concept of trusting people to pay a modest fee for software they genuinely find useful is terrific. And I use a lot of shareware (and pay the appropriate registration fees). But the manuals for most shareware programs are distributed as a text file unless you pay extra (and I generally don't). So I end up with very useful manuals in a very NON-useful form: a large text file on my hard disk. Sure, I can print out the manual, but this can consume enormous amounts of time, paper and printer ribbons (the QEDIT manual, for example, is some 5500 lines long). And besides, I can never find the manual when I want it. And even if I can, finding the information I want can be very hard. Aren't computers supposed to make life easier? Yet reading a document on a computer screen is still extremely primitive. Certainly you can use a useful utility like LIST, but this is still missing something. It's hard to navigate around in a large text file, to find the next chapter, or to locate key words. Using the FIND utility in such programs is some help, of course, but you have to type in the key word, and hope you have spelt and punctuated it properly. AUTOREAD is my attempt to fill this perceived gap. It works very much like LIST, but it allows you to progressively establish landmarks in the text and to go instantly to them. AUTOREAD allows the creation of several kinds of 'landmarks': * Chapter Stops * Pre-defined Keywords * Temporary Bookmarks These are all available via pull-down menus for easiest possible use. What all this means is that you can very easily create a comprehensive index to a particular text file, enabling you to instantly find the section or information you are looking for. It makes reading a text file on your computer as easy as reading a hard copy, and in some respects easier. 3: Shareware Notice ══════════════════════════════════════════════════════════════════════ AUTOREAD took a lot of effort to create. And I am still working on improving it. Please note that AUTOREAD is not, never has been, and never will be free or public domain software. It is shareware. The shareware concept is extremely simple. If you obtain a copy of a shareware program, find it useful to you, and wish to continue using it, you must send the requested shareware fee to the program author. Shareware relies entirely on trust. But it is a concept which has allowed the creation and distribution of a large body of excellent software at very low cost. If you find AUTOREAD of use, please print out and fill in the enclosed LICENSE.DOC document, and send it with the requested $15 shareware fee to: David R Grigg, 1556 Main Road, Research, Victoria 3095 Australia. NOTE: Most commercial software forbids you to make copies of it. But because AUTOREAD is shareware software, you are positively ENCOURAGED to share copies of AUTOREAD around, copy it for your friends, upload it to bulletin boards, etc. The only stipulations are that all those who use AUTOREAD for longer than a trial period of 14 days must pay the required shareware fee, and that AUTOREAD must be distributed with all the associated files, being: AUTOREAD EXE LICENSE DOC MANUAL ARD MANUAL DOC MANUAL IDX README BAT STATS DOC STATS EXE 4: Installing AUTOREAD ══════════════════════════════════════════════════════════════════════ AUTOREAD is extremely easy to install. The only file absolutely necessary to operating AUTOREAD is AUTOREAD.EXE, which you should copy either into the same directory as the documents you wish to use it on, or (especially if you have a hard disk) into a directory which is listed in your DOS PATH command (this is usually specified in your AUTOEXEC.BAT file). Many hard disk users have a directory called \TOOLS on their hard disk. This is a good place for AUTOREAD. To use AUTOREAD on a particular text file (as an example, say a file called MANUAL.DOC), you would enter the following at the DOS prompt: AUTOREAD MANUAL.DOC If you don't enter the file name, you will be prompted for it. 5: Files Created by AUTOREAD ══════════════════════════════════════════════════════════════════════ AUTOREAD maintains two different files of its own for every text file that you use it on. If you used it on a document called MANUAL.DOC, for example, AUTOREAD would create the following files: MANUAL.IDX MANUAL.ARD Unless you have changed the textfile since you last read it, the .IDX file will be created only the first time you use AUTOREAD on the text file. The .ARD file, however, is constantly read and rewritten. The .IDX file is an index of the starting points of each line of the text file, and enables AUTOREAD to very speedily locate parts of the file. If it offends you to have a lot of additional files in a directory, you can delete this file, but then AUTOREAD will need to recreate it each time you access the text file that it indexes. The .ARD file contains such data as the current location in the file, a list of chapter stops and their starting lines, and a list of keywords. Note that the .ARD file is an ordinary text file, which means that you can use a text editor to manipulate it directly. NOTE: If you just wish to use AUTOREAD quickly on a small file you wish to look at but will probably never wish to fully index and set up chapter stops on, you can append an option, -Q, to the command line, eg: AUTOREAD MANUAL.DOC -Q This ensures that AUTOREAD will get rid of its .IDX file on exit, and will not access or create an .ARD file. 6: The AUTOREAD screen ══════════════════════════════════════════════════════════════════════ If you are using AUTOREAD to read this manual, you are already in the default screen mode - Display Mode. 6.1 Display Mode ────────────────────────────────────────────────────────────────── This is the DISPLAY mode of AUTOREAD. Note the top line, in reverse colours, which indicates that you can press the ESCAPE or ESC key to bring up the AUTOREAD Menu Bar, or hold down the ALT key and then the press the X key on your keyboard to exit AUTOREAD. NOTE: It is most important to exit AUTOREAD in the standard way, by pressing Alt-X. Doing this saves important information. If you exit in any other way (ie, by simply turning off the computer, or by rebooting), this information will not be saved. At the bottom line of the screen you will see information on the current line number, the current search direction, and the pathname of the file being read. 6.2 Menu Mode ───────────────────────────────────────────────────────────────── Pressing ESC changes the top line of the screen to a Menu Bar. See the section on The AUTOREAD Menu Bar for further information. 7: Moving Around in Your Document ══════════════════════════════════════════════════════════════════════ The up and down arrow keys on your keyboard will scroll the text on your screen in the indicated direction. Pressing PAGE UP on your keyboard will move to the previous screen-full of information. (Unless you are at the start of the file, of course). Pressing PAGE DOWN on your keyboard will move to the following screen-full of information. (Unless you are at the end of the file, of course). Holding down the Control (CTRL) key on your keyboard and pressing HOME will go to the start of the file. Holding down the Control (CTRL) key on your keyboard and pressing END will go to the end of the file. It is also possible to move to specific areas of the file by using the AUTOREAD menu bar (see next section). 8: The AUTOREAD Menu Bar ══════════════════════════════════════════════════════════════════════ You can call up the AUTOREAD menu bar simply by pressing the Escape (ESC) key on your keyboard. The top line of your screen will alter to show a series of menu choices, like this: ┌────────────────────────────────────────────────────────────────────────┐ │ AUTOREAD: Go Chapter Keyword Mark Find Screen ???│ └────────────────────────────────────────────────────────────────────────┘ The first entry will be highlighted. You can move the highlight by pressing the left and right arrow keys on your keyboard. When the entry you want is highlighted, press the ENTER key on your keyboard, and a sub-menu will appear. Alternatively, you can simply press the first letter of your menu choice, and the sub-menu will immediately appear. To activate the Keywords sub-menu, for example, simply press the 'K' key on your keyboard. What follows is a brief description of each of the sub-menus and what they do. More detailed explanations are in following chapters. 8.1 Go ───────────────────────────────────────────────────────────────── The Go menu allows you to move quickly to different positions in the file: the beginning, the middle, the end, or to a specific line number. 8.2 Chapters ───────────────────────────────────────────────────────────────── This is perhaps the most powerful part of AUTOREAD. This menu allows you to find instantly any one of up to 200 'chapter stops', by selecting a description from a pull-down menu. They are called 'chapter stops' because the idea is that you can set up such stops at the beginning of chapters or major sections in the document. This menu allows you to find, create, delete or change an existing chapter stop. It also allows you to clear all existing chapter stops, or to automatically make chapter stops at standard points in a document. 8.3 Keywords ───────────────────────────────────────────────────────────────── An AUTOREAD keyword is like a FIND command for pre-defined strings. It means you can create a list of common or especially important words, perhaps from the index of the manual, and quickly point to them. Once you have chosen a keyword to find, AUTOREAD will quickly scan the file looking for the next occurrence of that keyword. Note that you can alter the direction of the search from this menu. This menu allows you to find, create, or delete keywords. 8.4 Marks ───────────────────────────────────────────────────────────────── 'Marks' is short for 'bookmarks'. They work in a very similar way to chapter stops, except that they are temporary (they vanish when you exit AUTOREAD), and the listing entries simply give the bookmark number and the line number, rather than a description. Bookmarks are intended as a quick way of placing a marker in the text while you look for some other information, and then being able to quickly return to where you left off. Note also that when you exit AUTOREAD, the current position in the file when you exited is stored, so that the next time you use AUTOREAD to read the file, the screen will be the same as when you exited the previous time. 8.5 Find ───────────────────────────────────────────────────────────────── This menu lets you search for any text (not a pre-defined keyword). You can specify the direction of search from this menu. 8.6 Screen ───────────────────────────────────────────────────────────────── This menu simply allows you to set the foreground colour and background colour of the text on the screen. 8.7 ??? ───────────────────────────────────────────────────────────────── Choosing this option will bring up an information screen about AUTOREAD. It is not a help screen (this may be built into later versions of AUTOREAD). 9: Go Menu ══════════════════════════════════════════════════════════════════════ The Go Menu looks like this: ┌──────────────┐ │ Top ^Home │ │ Middle - │ │ End ^End │ │ ------------ │ │ Line Number │ └──────────────┘ Move the highlight around with the up and down arrow keys. When it is on the selection you want, press ENTER on the keyboard. Alternatively, simply enter the first letter of your choice. You will note next to some of the entries their 'short forms', eg for Top you will also see ^Home. This means that you can enter the short form and have the action take place immediately without needing to call up the AUTOREAD Menu Bar. In other words, to go to the top (or start) of a file, you can either press ESC to get the Menu Bar, then G for the Go Menu, then T for top, or simply press down the Control Key on your keyboard and then the HOME key. This menu should be self-explanatory: 9.1 Top (^Home) ───────────────────────────────────────────────────────────────── Goes to the start of the file. 9.2 Middle ───────────────────────────────────────────────────────────────── Goes to the very middle line of the file. 9.3 Bottom (^End) ───────────────────────────────────────────────────────────────── Goes to the end of the file. 9.4 Line Number ───────────────────────────────────────────────────────────────── Lets you enter and go to a particular line number in the file. 10: Chapters Menu ══════════════════════════════════════════════════════════════════════ The Chapters Menu looks like this: ┌────────────┐ │ Find F2 │ │ Add │ │ Change │ │ Delete │ │ ---------- │ │ Clear │ │ Make │ └────────────┘ As indicated earlier, 'Chapter Stops' are perhaps the most powerful part of AUTOREAD. You can use it to move instantly to the beginning of various chapters or sections within the text file. This menu allows you to find instantly any one of up to 200 'chapter stops', by selecting a description from a pull-down menu. The Chapters Menu also allows you to add, change and delete such chapter stops, as described below: 10.1 Find (F2) ───────────────────────────────────────────────────────────────── This brings up a menu of the existing chapter stops. You can move the highlight to the wanted chapter stop by using the up and down arrow keys. Note that if there are enough chapter stops, the listing will scroll up and down within the box. You can also use PAGE UP and PAGE DOWN to move through the listing. Once you have selected your desired chapter stop, press ENTER, and the screen will immediately fill with the text starting at the desired chapter stop. 10.2 Add Current ───────────────────────────────────────────────────────────────── This allows you to set the current line (that is, the line currently at the top of the display screen) as a chapter stop. You will be prompted for a description. 10.3 Delete ───────────────────────────────────────────────────────────────── This will allow you to get rid of a particular chapter stop, which you identify from the same pull-down menu as for the Find function. You will be prompted to confirm the delete. 10.4 Change ───────────────────────────────────────────────────────────────── This will allow you to edit the description of a particular chapter stop, which you identify from the same pull-down menu as for the Find function. Note that in this version of AUTOREAD, Change does not allow you to alter the line number of a chapter stop. 10.5 Clear ───────────────────────────────────────────────────────────────── This allows you to get rid of ALL current chapter stops. Please use this carefully! You will be prompted to confirm the clear. 10.6 Make ───────────────────────────────────────────────────────────────── This is an extremely powerful utility, and makes the job of creating chapter stops in an existing document extremely easy, particularly if the document author has used a standard way of identifying chapter or section beginnings. Make allows you to scan the whole document, looking for a designated string of text, and setting a chapter stop once it has found it. It is possible to set a line offset from the searched for text, and a prefix for the description. An example will make this easy to understand. 10.6.1 A Make Example One of the first documents I used AUTOREAD on myself was the manual for the excellent shareware text editor QEDIT. This manual is some 5500 lines long. The document author had used a line of equal signs '====' to underline each chapter heading, and a graphic line '────' to underline each section heading. I first made a pass with Make, searching for the line of equal signs. Once I selected Make, I was prompted for the text string to search for. I entered four equal signs, =====. I was then prompted for a line offset. This allows you to specify a line OTHER than the one on which the text string was found as the actual chapter stop. In my case, since the wanted line was the line immediately ABOVE the line of equal signs, I entered an offset of -1. (If I had wanted the line of equal signs itself, I would have entered 0). I was then prompted for a prefix string. The real value of this is for sections or sub-sections, so I simply pressed ENTER instead of entering a prefix. The program then took about 30 seconds to scan through the whole QEDIT document and set up the chapter stops. AUTOREAD took the first text on the line I indicated I wanted the chapter stop on, and used this as its description for that chapter stop. I then wanted to set up sections as chapter stops, so I carried out another pass with Make. Once I selected Make, I was prompted for the text string to search for. I entered four graphic line characters, '────'. (I used the ALT key and the numeric keyboard to enter these characters - refer you DOS manual if you don't know how to do this). I was then prompted for a line offset. As again the wanted line was the one above the graphic line, I entered an offset of -1. I was then prompted for a prefix string. I now wanted to use this feature, to distinguish the section headings from the chapter headings in the Find Chapter pull-down menu. So I entered a hyphen and a space, '- '. These characters were placed before the description for all the chapter stops created during this Make pass. Another 30-40 seconds, and I had essentially the equivalent of the contents page of the manual in the form of a pull-down menu. Here is part of the chapter stops menu I created for QEDIT.DOC: ┌──────────────────────────────────────────┐ │ - COLORS │ │ - TABLE OF CONTENTS │ │ - ACKNOWLEDGEMENTS │ │ - INTRODUCTION │ │ - FEATURES │ │ - SYSTEM REQUIREMENTS │ │ - INSTALLATION │ │ CHAPTER 1. USERS GUIDE FOR QEDIT │ │ - QUICK START │ │ - MENUS │ │ - THE STATUS LINE │ │ - FILES │ │ - VIEWING AND GETTING AROUND IN THE TEX │ │ - CURSOR MOVEMENT │ │ - USING WINDOWS │ └──────────────────────────────────────────┘ 10.7 Make is extremely useful if you are the author of a document you want to use AUTOREAD with, and you need to make changes to the document after you have already used AUTOREAD on it. You can Clear the existing chapter stops, and use Make, to very quickly re-establish those stops at new line numbers, provided you have used some consistent means of identifying chapters and sections. This means need not be types of underline, as in the example above, but could be the word CHAPTER in capitals (Note that Make distinguishes between upper and lower case, unlike Find Text and Find Keyword), or a special character or series of characters (eg ---> ). The best way to learn how Make works is to try it out. Don't worry about making mistakes, you can always Clear and start again. 11: Keywords Menu ══════════════════════════════════════════════════════════════════════ A keyword is simply a text string to be found in your document, and the Find Keyword function works exactly as does the Find Text function, except that you don't need to type in the required text: you simply select it from a pull-down menu. The Index of a document is a great place to find useful keywords. The Keywords Menu looks like this: ┌──────────────┐ │ Find F3 │ │ Add │ │ Delete │ │ -------- │ │ Search DOWN │ └──────────────┘ 11.1 Find (F3) ───────────────────────────────────────────────────────────────── This brings up a menu of the existing keywords. You can move the highlight to the wanted keyword by using the up and down arrow keys. Note that if there are enough keywords, the listing will scroll up and down within the box. You can also use PAGE UP and PAGE DOWN to move through the listing. Once you have selected your desired keyword, press ENTER, and the screen will begin searching in the indicated direction for the wanted keyword, putting up a display of the current line number being searched. If the keyword cannot be found, an error message will appear. Note that unlike the Chapter Make command, Find Keyword IGNORES the difference between upper and lower case. That is, 'DOS', 'Dos' and 'dos' will all be found by the same keyword choice. 11.2 Add ───────────────────────────────────────────────────────────────── This prompts you for the text of a new keyword, which will be added to the list of existing keywords in alphabetical order. 11.3 Delete ───────────────────────────────────────────────────────────────── This will allow you to get rid of a particular keyword, which you identify from the same pull-down menu as for the Find function. You will be prompted to confirm the delete. 11.4 Search Direction ───────────────────────────────────────────────────────────────── This specifies the current direction of search. The default is DOWN, ie searches on increasing line numbers from the current line. UP searches to decreasing line numbers from the current line. GLOBAL searches from beginning of file. To toggle the direction, simply select this choice. 12: Marks Menu ══════════════════════════════════════════════════════════════════════ Bookmarks are just like chapter stops - except that they are volatile (they vanish when you exit AUTOREAD), and that they do not have a description, just an ID number and a line number. Bookmarks are intended as quick reference points to 'hold your place' when you are looking for something else in a file. You can only create a maximum of 10 bookmarks. The Marks Menu looks like this: ┌─────────────┐ │ Find F4 │ │ Add Current │ │ Enter │ │ Delete │ └─────────────┘ 12.1 Find (F4) ───────────────────────────────────────────────────────────────── This brings up a menu of the existing bookmarks. You can move the highlight to the wanted bookmark by using the up and down arrow keys. Once you have selected your desired bookmark, press ENTER, and the screen will immediately fill with the text starting at the desired bookmark. 12.2 Add Current ───────────────────────────────────────────────────────────────── This allows you to set the current line (that is, the line currently at the top of the display screen) as a bookmark. You will be prompted for the bookmark number you wish this line to be recorded against. 12.3 Enter ───────────────────────────────────────────────────────────────── This allows you to enter a line number directly for a new bookmark (ie, you don't have to have the display showing that line as the current line). You will be prompted for the bookmark number you wish this line to be recorded against. 12.4 Delete ───────────────────────────────────────────────────────────────── This will allow you to get rid of a particular bookmark, which you identify from the same pull-down menu as for the Find function. You will be prompted to confirm the delete. 12.3 Function Key Setting & Finding Marks ───────────────────────────────────────────────────────────────── Because bookmarks are mainly used for very rapid access to temporary locations in the file, AUTOREAD allows you to completely bypass the menu system in setting and finding bookmarks. While you are in DISPLAY mode and at a point in the text you wish to return to after looking somewhere else, hold down the SHIFT key and one of the function keys F1..F10. You will hear a warbling sound, indicating that the equivalent bookmark has been set at that point (ie, pressing Shift F2 sets bookmark 2). After you have browsed elsewhere, you can hold down the ALT key and the function key (F1...F10) corresponding to the bookmark you set previously. You will immediately jump back to the place you left. Note that you can use ALT and the function keys to jump to ANY bookmark, whether set with SHIFT + function key or set through the Marks menu. 13: Find Menu ══════════════════════════════════════════════════════════════════════ The Find Menu looks like this: ┌─────────────────┐ │ Find Text │ │ Last Find: │ │ --------------- │ │ Search DOWN │ └─────────────────┘ 13.1 Find Text ───────────────────────────────────────────────────────────────── This will prompt you for the text to be found. Once you have entered your desired text, press ENTER, and the screen will begin searching in the indicated direction for the wanted text, putting up a display of the current line number being searched. If the text cannot be found, an error message will appear. Note that unlike the Chapter Make command, Find Text IGNORES the difference between upper and lower case. That is, 'DOS', 'Dos' and 'dos' will all be found by the same keyword choice. 13.2 Last Find ───────────────────────────────────────────────────────────────── This retains a memory of the last text string you looked for, and enables you to select it again. Otherwise, it works exactly like the Find Text command. 13.3 Search Direction ───────────────────────────────────────────────────────────────── This specifies the current direction of search. The default is DOWN, ie searches on increasing line numbers. To toggle the direction, simply select this choice. 14: Screen Menu ══════════════════════════════════════════════════════════════════════ This menu allows you to alter the foreground colour and background colour of the displayed text for the duration of your current session with AUTOREAD. The Screen Menu looks like this: ┌────────────────────────┐ │ Foreground WHITE │ │ Background BLUE │ └────────────────────────┘ Note that the current colours are shown on the menu. Once you select the foreground or background colour, you will be given a pull-down menu of the available colours. Note that the colour change does not take effect until you have pressed ESC to return to the display mode of AUTOREAD. 15: To Other Shareware Authors ══════════════════════════════════════════════════════════════════════ It seems to me that AUTOREAD would be an extremely useful program to distribute with your shareware manuals on disk. However, it doesn't seem very fair to the users of your software to be expected to pay a second shareware fee (to me) for the use of AUTOREAD on your manual. For this reason, I will provide a special version of AUTOREAD which will be set up to read only your manual file or files, from the same directory as those files. You will need to pay me a shareware fee of $50 for this special version, and to write to me with the names of the files you want it to be able to read. I will then provide you with the special version. On the other hand, your shareware users will need to pay no additional fee to use AUTOREAD on your manual. You will find it very easy to set up the customised version of AUTOREAD to work with your manual, establishing chapter stops and appropriate keywords, so that your users will find your on-disk manual a truly easy-to-use and valuable reference. However, if you do not want to set up the appropriate chapter stops and keywords yourself, for an additional $25, if you supply me with a copy of your manual, I will establish the appropriate chapter stops and keywords and return the appropriate files to you. 16: Acknowledgements ══════════════════════════════════════════════════════════════════════ AUTOREAD was written using Borland's Turbo Pascal 5.5, a great compiler which goes on getting better and better, and making me less and less keen to move to programming in C. I used QEDIT Advanced 2.08 from SEMWARE as my text editor during programming and for some of this manual. I've also mentioned QEDIT in a number of places in this manual, to illustrate how AUTOREAD can be used to make access to a large text file manual easy, and I hope SEMWARE didn't mind me doing so! QEDIT is the best text editor I have ever used, and spoils you for all others. It is shareware, and I recommend you write to SEMWARE at 730 Elk Cove Court, Kennesaw, Ga, USA for their current prices. Most of this manual was written using PC-Outline from Brown Bag Software, also shareware, and a program I use intensively for manuals, reports, etc, where section numbering and renumbering is required. Write to Brown Bag Software, PO Box 60000, San Francisco, CA 94160-1719, USA for current prices. 17: Version History ══════════════════════════════════════════════════════════════════════ This is version 1.01 of AUTOREAD. There may well be a few bugs in it. I would be grateful if those who find such bugs could let me know. Similarly, if you have any ideas for ways of improving the product, let me know. 17.1 Updates ───────────────────────────────────────────────────────────────── 1.01 : (2 July 1990) - GLOBAL search direction added - fix to bug allowing line 0 to be displayed in status - fix to bug involving embedded '/' char in chapter description 17.2 Planned Enhancements ───────────────────────────────────────────────────────────────── In future, I plan to add the following features to AUTOREAD: * Support for 43-line and 50-line screens * Short-form function keys for most functions currently available only from the menus. * Auto-capture of keywords. * Mouse operation.
