- INSTRUCTIONS FOR READ
-
- READ.EXE is a program for reading and editing ASCII text files. The program
- requires a PC/AT compatible computer with a color monitor. If a mouse is
- detected in the system, it is automatically supported. You can type READ
- FILENAME at the DOS prompt to load a text file at start-up time, or you can
- run the program and then select a file.
-
- The file selection menu allows you to navigate to all drives and directories.
- Use the UP/DN ARROW KEYS, PAGE UP/DN, HOME/END or the MOUSE CURSOR to move
- the highlight bar (selecting the ".." token moves you up one directory). If
- you select a file by pressing the ENTER key, or by DOUBLE-CLICKING the LEFT
- MOUSE button, then the file will be loaded for editing. If you select a file
- by pressing the SPACE BAR, then the file will be loaded for viewing only (the
- F3 search and F7 print options will still be active). If you press ESCAPE
- from the menu, you will get an input prompt at the bottom of the screen that
- lets you enter a filename manually. If you specify a filename that does not
- exist, you will be asked if you want to create it.
-
- Press ESCAPE, or F10, to end your session with READ. If you have made changes
- to the document, you will be asked if you want to save the file. Press ENTER
- to save the document under its present filename, or enter a different name.
- To bypass the file save, press ESCAPE again. At this point you will be asked
- if you want to quit the document. The default answer is [N]o. It you press
- [Y]es, or ESCAPE, you are returned to the file selection menu. You can either
- select another file, or press ESCAPE one more time. You are then asked to
- enter the filename of a new document to READ (this gives you the chance to
- CREATE another file). Press ESCAPE at this prompt to end the program. In
- general, use the ESCAPE key to cancel options, and to back progressively out
- of the program.
-
- READ is capable of displaying and editing text files of virtually UNLIMITED
- size. When you READ a large text file (approximately 39K bytes or more), a
- set of temporary files is created in the default directory with filenames of
- the form {@}R****, where the asterisks are numbers indicating the segment
- number. Press F9 to go to another segment for reading or editing. Depending
- on the density of the text in your document, each segment can be up to 1500
- lines long. When you end your session, the original file is reconstructed,
- and the temporary file segments are erased.
-
- Press F2 to change the color of text on the screen (the text color reverts to
- the default yellow for each new document). Press F1 to display a HELP screen
- that summarizes the editing keys. If you just want to READ through a document,
- use the UP and DOWN ARROW keys to scroll the text, or use the PAGE UP and
- PAGE DOWN keys to go to the next full screen of text. The LEFT and RIGHT
- ARROW keys move the cursor along the lines of text. CTRL-LEFT ARROW and
- CTRL-RIGHT ARROW give you a fast cursor motion. HOME puts the cursor at the
- start of the current line, and END puts the cursor at the end of the line.
- CTRL-HOME puts the cursor at the beginning of the document, and CTRL-END puts
- the cursor at the end of the document.
-
- The MOUSE CURSOR can be used to position the editing cursor by clicking the
- LEFT mouse button. Also, you can place the MOUSE CURSOR on the UP and DOWN
- ARROW ICONS and click the LEFT button to scroll to the next full screen of
- text. Place the MOUSE CURSOR on the TOP or BOTTOM screen border lines and
- click the LEFT button to move the editing cursor UP or DOWN one line. Place
- the MOUSE CURSOR of the LEFT or RIGHT screen border lines and click the LEFT
- button to advance the editing cursor 10 positions LEFT or RIGHT. In general,
- the LEFT mouse button is treated like a RETURN key press, and the RIGHT mouse
- button is treated like an ESCAPE key press.
-
- Press CTRL-W to toggle the word wrap feature. The current file or segment
- will be processed so that long text lines are wrapped onto the editing
- screen. This will NOT alter the original file on disk unless you explicitly
- save the document. When you are entering text, words at the end of a line
- will be automatically wrapped onto the next line. The default setting is OFF
- for each new document.
-
- If you toggle the line indenting feature using the F12 key, the next line of
- text will be aligned with the starting column of the line above it when you
- press ENTER. Use the INSERT key to toggle the insert or typeover mode. The
- TAB key will insert or typeover five standard spaces in your document, but
- does NOT insert the ASCII TAB character. The DELETE and BACKSPACE keys are
- used for deleting text one character at a time.
-
- Pressing CTRL-Y will delete the current line and put it into the editing
- buffer. Text in the editing buffer can be inserted anywhere by pressing
- SHIFT-INSERT. To mark a block of lines for cutting and pasting, press SHIFT-
- DOWN ARROW to highlight the lines (use SHIFT-UP ARROW to unmark the lines).
- You can also highlight text by holding down the LEFT button and dragging the
- MOUSE cursor. Press ESCAPE to cancel the block edit. Press SHIFT-DELETE to
- cut the text into the buffer, and SHIFT-INSERT to paste the text from the
- buffer into your document. If you just want to copy text, use SHIFT-DELETE
- to cut the highlighted text, and then re-insert it using SHIFT-INSERT. The
- block of lines is still in the editing buffer. Move the cursor to where you
- want to copy the text and press SHIFT-INSERT again.
-
- READ offers a simple search and replace feature. Pressing F3 gives you the
- prompt SEARCH FOR. Press ESCAPE to cancel the search, otherwise enter the
- search string. Note that case is significant. The search string you enter
- becomes the default target for the next time you press F3. For large files,
- all segments are searched. If the search is successful, the line containing
- the string will be displayed as the top line on the screen, with the search
- string highlighted. You are then asked REPLACE WITH, where the default
- response is the current search string. Pressing ENTER, or ESCAPE, cancels
- the string replacement feature. If you type some other replacement string,
- that string becomes the default replacement string until you change it.
-
- READ will not alter any special ASCII characters embedded in your original
- document, but certain characters are treated in special ways. For example,
- existing TAB characters (ASCII 9) are displayed as single HARD SPACE char-
- acters (ASCII 255). Substituting a single SPACE for each TAB keeps text lines
- that may have a lot of TABS, such as deeply nested loops in computer source
- code listings, from expanding an unreasonable amount across the editing
- screen. Other control characters, such as NEW PAGE (ASCII 12), are shown as
- the equivalent control character in braces. There is a NEW PAGE character a
- few paragraphs above this one. This would cause a FORM FEED if you were to
- send this file to your printer.
-
- Pressing F7 sends the current document, segment, or marked block of text to
- your printer. You can press ESCAPE to cancel the print option, or you can
- press ESCAPE during printing to stop the process.
-
- You should find READ to be easy to use. A device error, file access error, or
- disk access error will cause a warning message to be displayed on the prompt
- line at the bottom of the screen. If your document becomes so large that you
- are about to run out of FREE work space (as reported on the prompt line) you
- will be prompted to save the file and then READ it again. When you READ the
- file again, it will be displayed in segments.
