(C) Copyright NEMCO 1983 WORDFLEX TUTORIAL SESSION 1. Welcome to word processing with WORDFLEX. This tutorial, consisting of 5 sessions, will introduce you to the main features of the WORDFLEX program. More complete technical information is included in the WORDFLEX User's Manual. You may decide to consult the Manual even during these sessions but this should not be necessary. This tutorial consists of five files named tutor1.txt through tutor5.txt which can be printed from IBM DOS using the command "copy tutor?.txt lpt1:" on your parallel printer (or on your serial printer if lpt1: has been redirected by the "mode" command). You may find it convenient to obtain a hard copy of this tutorial before you proceed with the sessions. The amount of material covered in each session is meant for a person without any experience in word processing and/or computer aided text editing. If you already have some experience, you may decide to go through more than one session at a time. ***Press Ctrl Pg Dn*** In this first session we will cover the following topics: WORDFLEX general features Cursor and screen control File handling WORDFLEX utilities WORDFLEX is an exclusively memory resident program. All procedures and commands as well as the entire edited text are memory resident during the session. This makes the program quite large but, in return, it speeds up its operation significantly. As a result, no temporary disk files have to be created during the session. The area in memory used for a temporary storage of the edited text and its manipulation is called the text buffer. WORDFLEX can subdivide this memory into a maximum of five separate buffers, each of them containing an individual file. In this tutorial we will refer to an individual file buffer as simply a buffer. Unless otherwise stated, this will also mean the currently selected file buffer. Each buffer is associated with a file ***Press Ctrl Pg Dn***  -2- name. This name represents either an existing disk file or a new file being created by WORDFLEX. The first subject covered in this session is the cursor and screen control. WORDFLEX uses some of the conventions of the BASIC screen editor: the cursor is moved by the arrow keys of the right hand keypad. All the keys of this keypad are used for editing functions exclusively; they cannot be used for numerical data entry (except with the Alt shift that generates all available ASCII characters). The Num Lock key is disabled in WORDFLEX. As in the BASIC screen editor, the Ctrl right arrow will advance the cursor to the beginning of the next word, and the Ctrl left arrow to the beginning of the preceding word. Words are defined as strings of characters delimited by blanks. Two other special keys used for cursor control are the Home and End keys. The Home key returns the cursor to the beginning (column 1) of the current line (different from BASIC editor). End acts the same way as in the BASIC editor: it moves the cursor just one space beyond the end of the text on the current line. ***Press Ctrl Pg Dn*** The Ctrl Home combination moves the cursor to column 1, row 1 of the screen. Ctrl End moves the cursor to column 1 of the last row containing text when the "cursor mode" is in effect. An additional command is used for cursor movement: Alt I - moves cursor to the temporary left margin (Session 5.) WORDFLEX allows you to move through the text using two different methods: pressing Ctrl Pg Dn will display the next screen (24 lines of text). Ctrl Pg Up will display the previous screen. Pg Dn will scroll the screen by 12 lines, Pg Up scrolls the text by 12 lines in the opposite direction. You can scroll the text continuously by toggling in the "scroll mode" with the Scroll Lock key. The vertical arrow keys will move the text up and down. Try it now. The scroll mode disables some commands and gives a new meaning to others. The vertical arrows scroll the text up or down. The Ctrl Home key in the scroll mode will cause a display of the first screen of the buffer, the Ctrl End key in scroll mode causes display of the last screen of the buffer. ***Press Ctrl Pg Dn***  -3- Practice now the cursor movement without touching any other keys. If you inadvertently touch any key from the main keyboard, the display will say "screen modified". In order to proceed with your cursor movement practice, you can get rid of that message by pressing F9, as will be explained in the next session. The next subject of this section is file handling. WORDFLEX session starts from IBM DOS by typing "wx filespec". The string "filespec" stands for a name of an existing file or a new file to be created by WORDFLEX in the current directory. The filespec has to be entered and it can contain the path information (DOS Version 2.0). WORDFLEX does not work on unnamed file buffers. WORDFLEX editing session is terminated by pressing F10. Two warnings are issued before the IBM DOS is reentered; the file buffer(s) have to be stored during the session since there is no way to recover their contents once the session has been terminated. WORDFLEX uses four special function keys for file handling: ***Press Ctrl Pg Dn*** F1 - lists file F2 - selects one of the active file buffers F3 - loads existing file on the buffer or associates the buffer with a new file name F4 - stores current file buffer as a disk file Try commands F1, F3 and F4 now. If you have enough memory, load file tutor2.txt on buffer 2, tutor3.txt on buffer 3 and so on. By doing so, you will also be able to test the command F2. Use F4 with caution! If you have enough space on this (or another diskette), store the files under other names since, if you inadvertently modify the text, the new file will replace the old one. WORDFLEX does not create backup files automatically. There is no need for backup files since the original file is not modified until the store file command is invoked by F4. Nevertheless, when editing an important and/or lengthy text, you should periodically save the buffer on the file associated with the buffer and, in addition to it, on a file with suffix .bak or similar. The last subject of this session are WORDFLEX utilities invoked by Alt A, Alt H and Alt S. The help command is invoked by Alt H and the result is a display of the help.txt file on one screen. This display, as well as the ***Press Ctrl Pg Dn***  -4- displays created by the Alt A and the Alt S command, has no effect on the edited text. Esc will take you from this display back to the text being edited. Try the Alt H command now. The next WORDFLEX utility is the status display invoked by Alt S. This display contains the summary of file names associated with the individual buffers, memory available and other information. Its usefulness will become apparent as you gain more experience with WORDFLEX. The next WORDFLEX utility is the "alter parameters" utility invoked by Alt A. The display is self explanatory: it lists options and their current values. The values displayed when a session is initiated are the default values of WORDFLEX. The "value" TRUE means that that particular option is in effect, the "value" FALSE indicates the opposite. At this point there is no need to modify any of these options; during the following sessions we will be referring to the Alt A command quite frequently. The last utility invoked by the Alt U command is the file handling utility. It allows you to display file directories, rename, delete, hide and unhide files. More on it in the last tutorial session. ***Press Ctrl Pg Dn*** This concludes the first WORDFLEX tutorial session. L‰DÆDÿvšyVš- ‹å]Ê è¸ Pš ‹
