Welcome and Greetings to: Black Magic, The Hypertext Word Processor Black Magic is a revolutionary program designed to integrate ìthe power of hypertext into that of word Processing. Hypertext is a concept that is based on relating information ìby association. This is opposed to the typical database view ìof relating information in a rigid structure based on ìfields and records. With hypertext you are instead linking ìtogether ideas and concepts into a cohesive whole. As an ìexample of information that is linked by association, ìconsider this. Remember back to when you first learned to ìdrive a car. The first thing you may remember is you first ìaccident. This is information that is linked by ìassociation. With hypertext, you can set up this type of ìinformation structure - one that works like your own mind. Hypertext relations (links) are shown by symbols embedded in ìthe text. These symbols are a pair of Squares, Triangles or ìDimonds. To active a link, move the cursor between the ìlinks below and press <F1>. Do this now ... (Please Select To Continue) n As you can see, pressing <F1> jumped you forward to this ìscreen. That is the purpose of the <F1> key - To move ìforward one link. The opposite of <F1> is the <Esc> key. ìThis simply jumps you backwards one link. Try pressing ì<Esc> now and then return to this screen (Remember - <F1>. As you just saw, pressing <Esc> jumped you back to the ìinitial screen and <F1> brought you back to here. ìAdditionally a mouse can be used to read a document. With a ìmouse, the left button is used to go forward a link, and the ìright button is used to go backwards one link. Using the ìmouse is as simple as pointing at a link (anything ìsurrounded by symbols) and clicking the appropriate button. Just as any other word processor, there are other keys that ìcan be used to move through a document. These include the ìcursor keys, <PgUp>, <PgDn>, <Home> and <End>. Now that you know how to read a hypertext document, select a ìtopic from the below list or choose one of the links above. Link Types
Graphics
Reading Commands Other Commands 6 ;Hypertext < =How To Order , @New Features u <PgUp> & <PgDn> As in many other word processors, the <PgUp> and <PgDn> keys move the cursor by screens of information. Moving the cursor this way is much quicker than the arrow keys. u <Home> & <End> The <Home> and the <End> keyts can both be used to speed your navigation through a hypertext document. The <Home> key simply moves the cursor to the beginning of the line that it is on. Similarly the <End> key jumps the cursor to the last position on the current line. The use of these two keys can also be extended to Block Marking. When a block is defined, pressing the <Home> key will change the marked area on the current line to the first character. Likewise the <End> key extends the selection to the end of the current line. Link Types ... Black Magic features three different link types: Reference Links, Note Links, Replacement Links, and G ADOS Links. Reference Links are the primary type of link that you have encountered to date. They are represented by a pair of green triangles surrounding a block of text. A reference link is an actual physical jump to another section of the document. This is an example of a reference Link. Note Links are simply transient temporary links that appear on screen in a small window. Note links are useful for making comments on the original text, or simply providing additional information that would be nice to know but not required. This is an example of a Note Link. The third type of link is the Replacement link. Replacement links, true to their name, simply replace one block of text with another. This is very useful when you are unsure of your audience's knowledge. It gives you the ability to use highly technical terms, by simply making them replacement links. Thus -> SCUBA o That was a reference link. It jumped you to another completely different section or 'Node' of the document. Note that it is still contained in the same file. There are now two ways to return to the previous Node. First simply press <Esc>; this will return you to the last link that you were at. Secondly, select the reference link below. This link will loop back to the previous scree. This demonstrates the ability of Black Magic to create 'Looping Links'. (Select To Continue) iNote Links are enclosed in a small window that appears in the upper right corner of the screen. ìThe window is scrollable, and can contain as much ìtext as is desired. The window is also ìresizeable and can even can contain a graphic. One restriction on a Note link is that they are ìlimited in that you cannot link outwards from ìthem. Their purpose is simply for providing ìcomments or supplemental information. T Self Contained Underwater Breathing ìApparatus Graphics ... As you can see from this screen, graphics are able to form an integral part of a hypertext document. COLLAT The blue circle towards the upper left of the graphic along the margin, is called a graphic indicator. It is there to give you a way to refer to the graphic to access the links. Select To Continue o Graphics Con't As you just saw, graphics can be integrated into a hypertext document. Additionally links can be forged outward from a graphic, as you see below. COLLAT ' F ? If you will notice, there is a circle with an 'X' in the ìgraphic. This circle indicate hypertext links outward from a graphic. To access one of these links, either click on it with your mouse, or move the cursor onto the graphic indicator and then press the right arrow again. Select To Continue o Graphics Con't As you will notice, the graphic link indicator blinks when you move onto it. This is to indicate that it is selected. Then if you press <F1>, you will activate that link. To return from that link, press <Esc> as you do for any other link. If there are multiple links in a graphic, continue using the left and right arow keys to cycle through them to the one that you wish to select. To exit the graphic links, either press the left arrow until you are out of the graphic, or press the down arrow or up arrow. This is all that you need to understand to use graphics and links in Black Magic. ?Now jump back one link and practice with the graphics that are there. ? h
$Reading Commands ... $ There are several other optional commands that may be used to enhance the reading of any Black Magic DocuYment. Note - these are only optional - all you really need to know is <F1>, <Esc> <PgUp> and <PgDn>. These merely streamline it as I have said. Key Combination Command <Alt> <F1> Collapse <Ctrl> <F2> Map Document <Alt> <F2> Reader Mode <F10> Menu <Ctrl> <ArrowKey> Jump By Link <Alt> H Show/Hide Links <Alt> C Configure Black Magic <Ctrl> F Find <Ctrl> A Again <Ctrl> O Set Search Options <Alt> - <NumberKey> Place holders (Other Black Magic Commands)
Other Commands Excluding commands related to reading hypertext documents, Black Magic features several other commands that are useful when reading a hypertext document. T .hese . are listed below, activate the links on those you are interested in. Key Stroke Command <Shift> <Arrowkey> Block Definition <F10> P Print <F10> U File Utilities <F7> Run A Macro <Shift> <F7> Define Macro <F10> F File Operations <Shift> <F9> ! Open File <Alt> <F10> " !Exit <Shift> <F10> # "TSR Wait State <F10> F E $ #Export Text $Reading Commands Collapsing A Document The Collapse command is used to condense a document back into its * +original state The use for it is to find your way back to the beginning of ìa document when you are deep inside it. To execute it, ìsimply press: <Alt> <F1> This will then initiate the collapse process. It may affect the screen adversely at first as Black Magic collapses the document, however the screen will be updated when it is completely collapsed. Note when you are deep inside a large document, this can take some time. e Mapping A Document The Mapping command calls up a graphic 'map' of the document. This map show the document is a network of interconnected reference links. To execute this press: <Ctrl> <F2> Try this now to see the document as a whole. As you saw, the map is composed of three windows, the largest being the map itself, and the two others being a viewer into the selected node and a legend that explains how to use the map. The numbers inside of each node are simply the internal window numbers that Black Magic uses to refer to the node. They are displayed there simply as a reference for you to use - They have no "absolute" meaning in the sense that they change with changes in the document's link structure. . 1 2Reader Mode 1 2 For those of you that are using MAGREAD to read this, feel free to skip right on by, it doesn't concern you. For those using MAGIC.EXE to read this, continue on. Black Magic has two distinct modes of operation: Reader Mode and Authoring Mode. The default upon startup is Authoring mode. In the authoring mode, you have the full capabilities of Black Magic to edit and alter documents, while in the Reader mode you are simply a browser where you cannot alter anything. The difference between Reader mode and Author mode is seen on screen on the bottom status or command line. At the left hand edge of the screen where the filename is, there is either: File: C:\MAGIC\FILES\FILENAME.MAG ----> Author Mode OR Read: C:\MAGIC\FILES\FILENAME.MAG ----> Reader Mode The advantage to being in reader mode when using MAGIC.EXE is twofold: ,Document integrity and )Jump By Link. The Menu Pressing <F10> calls up a menu along the bottom of the screen from which many choices can be made. The menu is a .Lotus 123 style moving bar type menu that can be accessed by using the arrow keys or the first letter of each item on the menu. The menu gives you access to: *Block Commands +File Commands ,Search Commands -Print Commands -Config Commands /DOS Utilities Commands " 0Exit Command Note - If you are either using Black Magic in 1reader mode, or you are using the MAGREAD utility some of these commands may be unusable. )Jumping Link by Link ) When you are using MAGREAD.EXE to read a Black Magic Document, or when Black Magic is in 2Reader Mode, pressing the Control key in conjuction with the left and right arrow keys will jump you through all the links in any one window one by one. This is very handy for quickly scanning a document and determining what links you wish to focus in on in depth. N Show/Hide Links One of the problems with hypertext systems to date is that when many links are available to the reader, the temptation is very strong to simply browse through the links and never read anything in depth. In essence you go on a 'tour' of a document, but don't necessarily learn anything. To combat this, there is a command in Black Magic to simply show or hide all the available links instantly. This command is invoked by pressing: <F4> This will hide all available links, and then pressing: <F4> Again will redisplay the links. t Configuration Screen Pressing <F10> U C calls up a configuration screen through which you can / 3alter its defaults. Among the things that ìcan be altered are the default paths, colors, Show/Hide ìlinks, and Bookmark settings. u , 7The Find (Search) Command , 7 The Find command is used to do a text search for a particular piece of text. To execute this command, press: <Ctrl> F Or K<F10> LS MF A / 4dialog box will come up for you to enter in the text ìthat you wish found. After entering the text and pressing <Enter>, Black Magic will search for the text and then either bring you to it or report that it could not be found. There is one thing to note about the Find command, it is limited to the text in the current window only - It does not search across links. Related Commands: 5Again 6Setting Search Options m 5The Again Command 5 The Again command is used to repeat the last Find command. It uses the same text string, merely repeating it. To invoke the Again command, press: <Ctrl> A Related Commands: 7Find 8Setting Search Options 6 8Search Options 6 8 Black Magic has several search options with which you can customize the searching process. These options include control over Whole Word Vs Partial Word Searching, Ignoring the Case, and J CGlobal Vs. Local search control. These options are controlled by pressing: <Ctrl> O This brings up a / 9dialog box that is controlled by the cursor keys, from which these options can be changed. d 4 5Place Holders Markers or Place Holders are invisible locators that you can ìembed within your text to quickly access any given location. ìOnce a marker is set, you can access it instantly from ìanywhere else in the document. To use a marker press <Alt> <NumberKey>. There are a maximum of nine (9) markers at any one time. There is no correlation between the number of the marker and its location in the document. The person defining the marker makes the choice as to where marker number one is placed and so on. It is a completely arbitrary process. To set a marker, press: <ALT> - <NumberKey> Here <NumberKey> is again used to indicate any number from 1 to 9. This will set marker number <NumberKey> at the line that the cursor is on. To erase any given marker, merely set a new one in its place. 1 :Select To Continue b ' *Block Definition ' * Blocks are defined in Black Magic by simply holding down the <Shift> key in conjunction with the <ArrowKeys>. Defined blocks are indicated by inverse video. In Black Magic (not MAGREAD.ARC), blocks are the basic unit for text ìmanipulation. They can be Cut, Copied, Pasted, Boldfaced, Undelined, Italicized, and Linked. In MAGREAD.ARC and reader mode of Black Magic, the purpose of Block Marking is to provide a way to $ %export text sections of a document to a dos text file. To mark a Block, press the shift key and move the cursor with the arrow keys, in order to highlight the desired block. t -Printing Text - You may wonder how Black Magic handles printing in a hypertext environment with many links or nodes. Black Magic handles this very simply, by only printing the 'Current Text Stream'. The Current Text Stream is simply that piece of text that can be reached only with the cursor keys and <PgUp>/<PgDn> - NOT using <F1> and <Esc>. For example If you were to issue the print command now, it would print out from "Printing Text" to "Printer Options Dialog Box." To print put the current text stream, press: <F10> F P G This will start sending the text to the printer, and Black Magic will display a message to that effect. Printing operations can be configured by accessing the Printer Options % &Dialog Box. w /File Utilities ... / In order to free you from having to exit to DOS every time you wish to do some minor file manipulations, Black Magic has the ability to: Delete, Copy, And Rename files. These file utility functions are located on the (logically enough) on the Utilities Menu. This is accessed by pressing: <F10> F U This brings up a bottom line menu from which you can choose either: Delete Copy Rename To do any of these actions, simply choose which option you desire. Then a dialog box will come up and prompt you for the filenames that are involved. After you enter the filenames, Black Magic will perform the utilities function. Note - When deleting files, Black Magic will request confirmation, to protect you from accidental deletion. f Running A Macro Macros are simply a series of prerecorded keystrokes that can be played back upon request. By recording commonly used sets of keystrokes, many commonly used procedures can be easily reduced to two keystrokes. Macros are stored on disk as a as a file with a name of the form: G.MAC Where the 'G' could have been any letter in the alphabet. To run a predefined a macro, simply press: <F7> G <Enter> Note - the 'G' here could have been the filename of any of the macros, not just G. After <Enter> is pressed, the macro will be executed. Defining A Macro About Macros <----- Click Here to learn what a 'Macro' is To define a Macro, press: <Shift> <F7> This puts the prompt: Mac: On the Command Line. Now you are required to enter a one character alphabetical name for the macro. (An example would be 'G' or 'A' or any other alphabet character). If the macro name that you have specified already exists, then Black Magic will alert you to this. Once a name is entered, Black Magic places the name next to the 'Mac: ' prompt and displays the number 255 next to it. This number represents the amount of keystrokes left in the macro. You start with 255 keystrokes available to you per macro and it counts down as the macro is created. Select To Continue e Macros Con't One you are done with your macro, simply press: <Shift> <F7> Again to end the Macro, saving it to disk. Note - If you exceed the amount of keystrokes available to the macro, Black Magic will end the macro for you, and save it to disk. Note - At Present time there is no way to edit macros. e +File Operations + Black Magic supports many file operations that are useful to simply readers of hypertext documnts. These are accessed by pressing: <F10> F This pulls up a menu of the available options. From these options, the ones that are of interest are the following: Open - This command loads a file. Files - This command calls up a listing of the available files on the current drive/directory. The filter can be changed by entering a new one. Change Dir - This command changes the current working directory to a new one. Import/Export Text - When a block is marked, this ì command will export the block to a DOS ì text file. a Open A File To load a file in Black Magic, press: <F10> F O And enter the name of the file and then press <Enter>. The file will then be loaded. Alternatively, you can press: <Shift> <F9> To open a file. Note: The default filename extension for Black Magic files is .MAG. Any files that wish to load with this extension, need not have it specified. Any other files to load with another extension must specify the extension. n ! 0Exiting 0 To leave Black Magic, press: <Alt> <F10> Alternatively, you may press: <F10> F E Note - When you exit !, Black Magic will ask you if you want ìto leave a (bookmark ( in the file. & 'About Bookmarks "TSR Wait State Black Magic is an application that operates in what is called ( )"Graphics Mode". When you run a TSR program on top of a program operating in graphics mode, you tend to get an entirely disrupted screen when you return to your main application. This is because few TSRs will restore the screen when you exit them. To get around this, Black Magic was designed with a "TSR Wait State". The TWS, is simply a mode that you put Black Magic into before running a TSR. It ensures that the screen is properly updated upon return from the TSR. To activate the TSR wait state, press: <Shift> <F10> Now the TSR can be run, with the need that you press <Esc> when you return to Black Magic. " u # %Exporting Text % Black Magic can easily export text from any hypertext document to an ASCII file. This allows you to easily excerpt parts of documents for your own reference. To export a section of a document, first mark it as a ì 'block, and then press: <F10> F I E Black Magic will then prompt you for the filename to export it to. After you have entered the filename and pressed <Enter>. The marked block will be written to the ascii file and the block marking vanishes. Note - If you mark an area containing links, Black Magic will simply export the text that was marked and not the link markers. # c &About Dialog Boxes Dialog Boxes are a fairly standard way to solicit information from the user. A dialog box is simply a full or half screen window from which choices can be made to configure some aspect of Black Magic. Examples of dialog Boxes used in Black Magic include the Search Options Box, The Configuration Screen Box, and The Printer Options Box. Dialog Boxes present various options for the user to alter. The method that you employ to alter these options varies depending on what you are altering. For Example (What you are altering is in italics) Dialog Box Option Method To Alter Line Spacing: 2 Enter a new Number Page Numbering: No Press "Y' or "N" Header: On Press <RightArrow> or <LeftArrow> Driver: HP Laserjet II Press <RightArrow> or <LeftArrow> Not - the <UpArrow> and <DownArrow> keys are used to scroll through a dialog box. & uSBookmarks are simply ìpointer to your current location in a file. If you answer ìYes to the Bookmark Query, Black Magic will create a file ìnamed: FILENAME.BKM Where 'FILENAME' is the name of the file that you exited ìfrom. Upon reloading this file, Black Magic will ìautomatically jump you to the link you were in when you ìexited. r"Graphics Mode". This means that every screen in Black Magic is actually a graphics picture as opposed to a screen of text characters shoriginal state. By original I mean how it was ìwhen the file was loaded without a " (bookmark. h @New Features - V1.3 Black Magic version 1.3 has several new features including: DOS Links, Global Searching, and a revised Menuing system. G BDOS Links J EGlobal Searching Revised Menuing System The Config Screen is accessed by pressing <Alt> ìC or <F10> U C. A full screen menu then comes up ìfrom which various changes can be made to the ìmanner in which Black Magic operates.

The typical use for markers is to get somewhere in the document FAST. They let you jump to the different nodes in a docuement easily because you don't have to find the link originators for those nodes. : limitations. Their first limitation is that any marker is line specific, ìnot position specific. What this means is that any marker ìwhen activated will bring you to the line that it was set ìon, but not to the specific position. The other limitation ìthat markers have is that they are not saved to disk with ìthe file. They are strictly temporary pointer to a location. ìA logical consequence of this is that when the line with a marker is deleted, so is that marker. Markers ;Hypertext Hypertext is a new way to manage information, it blends text ìand graphics together with an interactive reading process to ìcreate a new learning experience, a hypertext experience. 7 8Origin Description Hypertext is essentially interactive reading of 3 D documents. Reading a book is a one dimensional linear process, you start at the beginning, and (generally) you go straight through to the end. It is a one dimensional process, the path of reading being a straight line through to the end. Hypertext is not like that. In a hypertext document any block of text or graphics can be associated (linked) with any other block. Once two blocks are linked, they provide a instant gateway to each other. 9 :Linking ; <Select To Continue ntHypertext was first conceived by Vanevar Bush, ìPresident Roosevelt's Science Advisor, in 1945. His term ìfor it was a Memex. And as he envisioned it, it would aid ìa researcher in pulling together diverse information from a ìvariety of source. Not knowing of digital computers, he ìpictured it asbeing run by photocells and microfilm. The actual term 'hypertext' was coined in the mid sixties by ìa technical visionary named Ted Nelson. As he saw it, it ìwould consist of seamlessly binding all of man's knowledge ìinto one linked framework where everything is linked to ìeverything else. While many people have been skeptical about the possibility ìof Ted Nelson's Xanadu Project succeeding, recent ìdevelopments indicate that it may actually happen. And ìhopefully it will. bThis "linking" of blocks ìallows documents to be built with many levels. For example, ìa document could be written with levels that accommodated ìboth beginners and experts. <Hypertext Con't The levels to hypertext form both the interactive nature of hypertext and the 3 dimensional aspect of hypertext. Hypertext is interactive because the choice of activating the link between two blocks or levels is up to the user. This means that a hypertext document is not necessarily the same each time it is read. Different readers can (by activating different links) arrive at the same point in a document and have learned different things. Hypertext is 3 dimensional because it allows you to work in more than one dimension by linking blocks to other blocks to form different levels to a document. ; < =How To Order E >Order Blank Black Magic has now been released as a Shareware product. ìShareware is what is called a means of 'Alternative ìDistribution'. Essentially it is a way of letting you try ìand use the software comprehensively. Then if you like the ìsoftware and wish to continue using it - then you pay for ìit OR you voluntarily erase it from your hard disk or ìfloppies. Black Magic may be obtained in several ways including: = >1. Downloading It. ? @2. Purchase a copy from a shareware distribution house. A B3. Order it from us. 4. Get it from a friend. C DOrders s 1. Downloading It. This is obviously free or near free. Black Magic has been ìuploaded to most of the major Networks including ìCompuserve, Bix, and Others. The files that we have ìuploaded include: MAGIC.ARC Black Magic Shareware program MAGIC.BAT Needed to properly un-arc MAGIC.ARC MAGUTIL.ARC Utilities (Grabit.COM, Hypertext Manual) ì MAGUTIL.BAT Needed to properly un-arc MAGUTIL.ARC MAGREAD.ARC Black Magic Public Domain Reader MAGREAD.BAT Needed to properly un-arc MAGREAD.ARC MAGDEMO.ARC Demo Hypertext files MAGDEMO.BAT Needed to properly un-arc MAGDEMO.ARC One thing to note, is that these are big files, and to ìdownload them form a commercial network such as compuserve ìwould probably cost as much as to buy our evaluation kit. AA2. Purchase a copy from a shareware distribution house. Shareware distribution firms are simply companies that ìacquire Shareware software and then redistribute it. Black ìMagic has been sent to a number of these companies ìincluding: PC-Sig and Public Brand Software.

The basic idea is to show both your ìwork and your notes at the same time and the ìrelationships between them. - A BDOS Links DOS Links provide a way to integrate a the power of hypertext into existing DOS applications. The DOS Link when activated, unloads Black Magic from memory, and runs a user created batch file. This batch file can contain directions to run any program or sequence of programs. Then when the batch file terminates, Black Magic is then reloaded with the same document file that you were reading at exactly the same place that you left. This maintence of context is very important as it allows people to freely leave and enter hypertext without having to worry about what file to load or other details. HActivate the link below to see a demonstration of a DOS link that exits to DOS, displays a directory, and then waits for the user to press a Key before returning to Black Magic. I DOS Link DEMO Comment: The above demo will only work properly if your copy of Black Magic is loaded into a directory \MAGIC. NOTE: IF you are using Magic to read this, you will have to press <F1> twice to activate the link.
