Computers don't just calculate with numbers—they can also work with text. Five-inch disks can replace stacks of files. Computers can sort, search, select, and update any kind of information. They can focus information. In this sense, the computer is like the ruby crystal in a laser. Ordinary random light waves are transformed and concentrated through the ruby into a tight powerful beam. Computers can do the same for information.

Electronic text is more "liquid"," easier to work with, than words solidified on paper (hard copy). This is what makes word processing special: the extrordinary editing power it gives you. Distinctions between a rough draft and a final draft are meaningless; the work is typed, changed dynamically, and stored to disk. It can then later be recalled, revised, and printed out. Very little retyping is necessary. What a boon for anyone who writes.

Converts to word processing immediately notice an improvement in their writing. The entire manuscript becomes "alive," not committed to paper. Changing a word or a sentence, inserting a line or a paragraph are all accomplished with ease. For example, take just one key, the backspace key (called RUBOUT on some computers or terminals). When this key is struck, the last character typed is erased from the screen. Compare this to the frequently elaborate typewriter correction schemes.

Besides the disk file, which has already been mentioned and which will be explained in greater detail later, an important concept in word processing is the cursor. Named after the clear plastic side on a slide rule, the cursor shows you where the next character you type is going to appear. It usually looks like an underline, _, or a solid square. Users familiar with any computer have already encountered the cursor. The computer itself doesn't need a cursor; but since you can type anywhere on the screen, the cursor is vital so that you can know where you are.

The cursor can be moved up, down, left, and right with special keys, usually with arrows on them. To correct the following line:

The quick brown dox jumped 

you would either press backspace ten times, erasing the text as you go, or press cursor-left ten times. The cursor moves over the characters without erasing them. It is then resting on the d:

The quick brown dox jumped

You can correct the error by typing f, which overstrikes (replaces) the d.

The quick brown fox jumped

The cursor can then be moved to the end of the line (ten cursor-rights), and typing resumed.

This sounds harder than it really is. Cursor editing becomes second nature after only hours of use. The cursor UP/DOWN keys can reach lines of text above and below the current line. It is like rolling a typewriter's platen up or down, but with one important difference—the "paper" is one continuous, long sheet.

Two very special functions are insert and delete. Insert lets you add text in the middle of a line, by pressing INSERT to insert spaces in the text, and then typing in the word. For example:

To be or to be,that is the question. 

The cursor is placed on the second to, and INSERT is pressed four times (three for n-o-t, and one for a space):

To be or     to be,that is the question.

The word not is then typed:

To be or not to be,that is the question.

Delete is used to erase text. As distinguished from mere backspacing or spacing over a word, delete closes up the space after the deleted word.

Take out a word 

Take out a word

Take ut a word

Take a word

Insert and delete can also act on words, sentences, lines, or entire paragraphs in a similar way.

A file is simply a permanent record of your text. When the computer's power is turned off, it forgets everything except what is "burned" (in ROM memory) into it permanently. Your text is obviously not "burned in," or you couldn't ever change it. If you have a blackout, or a fuse blows, say good-bye to your text.

Catastrophes aside, you certainly don't want to leave your computer on all the time, or keep the computer tied up with your text forever. Fortunately you can save your text on disk, ready for any later revisions. You can type it one time, save your text, and print it out when convenient.

Since a disk can store more than one document (unless it's very long), you and the computer must have some way to distinguish and separate one file from another. This is usually done via a directory, a list of filenames. You access a file by giving the computer the file's name.

"Scriptor," the word processor program at the end of this article, has many features usually found only in professional word processors, but it lacks a few features such as search and replace, justification, data base merge, etc. Also, it is written in BASIC, so it can be rather slow at times. It is, however, aided by several machine language subroutines for time-critical situations such as disk input/output and some editing features.

Program 1 is the Scriptor program itself. Type it carefully, since it contains many critical machine language DATA statements. Extra time spent in typing it in will reward you with a smoother, bug-free word processor. Remember to use the Listing Conventions. Use the Atari logo key to enter inverse video. To give you more memory for text, Scriptor deletes a substantial portion of itself after it initializes (sets up). Don't worry—the program is busy running while the screen flashes; it just takes awhile. The setup lines from 5000-6999 are automatically erased.

If you quit the program and try to run it again, the program will automatically try to re-RUN itself anew from disk. If you've changed disks, you'll need to reload it yourself. You should SAVE the program with the filename "D:SCRIPTOR" or change line 455 appropriately. Be sure to SAVE Scriptor after you've typed it in, before you run it, or you will find a sizeable chukn of your typing erased when you exit. You can free up more memory for text by deleting the "help" function. Take out all lines from 1570 to 1700 and remove line 775. If you'd rather keep this handy aid, leave those lines alone.

If you get the message "Error in DATA statements" when you run the program, you need to check your typing of the machine language DATA statements at the end of the program. Also make sure you haven't typed a letter O for a zero (the zero is thinner than the O).

If you have an Atari 825 printer, you will need to type in the lines in Program 2. This will replace the lines used for the MX-80 with lines applicable to the 825 80-column printer. If you have another pritner, refrain from using special characters such as underlining, and you will probably be able to get one of the sets of lines to work.

Scriptor is a full-scrolling, character-oriented word processor. The use of cursor control keys is similar to normal Atari editor functions, with these exceptions.

1. <RETURN> is used only to force a carriage return, as at the end of a paragraph, or to print a blank line. The computer will format your line when you print it out, so just type continuously. Do not press <RETURN> at the end of each line. Pressing <RETURN> prints a black-arrow at the end of the line and erases all text to the end of that line.
2. Insert and Delete character (CTRL-INSERT/CTRL-DELEETE) work on whole "paragraphs." A paragraph is a block of lines from the cursor to a "back-arrow." If there is no back-arrow, one is assumed at the end of text. Therefore, Insert and Delete can be quite slow if you don't have a back-arrow somewhere.
3. Insert and Delete line work on the entire document. The screen will blank during this operation. This is normal and speeds up the process, as it can be slow on long documents.
4. All TAB controls work normally, just a little slower. <CTRL-K> will clear all tab settings.
5. <CLEAR> will not clear the screen. It is used to erase all or part of the text. Press <CLEAR><A> to erase all text. Press the Atari logo key to abort the erase function.
6. The break key is disabled. Use <CTRL-Q> to exit the program.
7. The ESC key enters the "mini-DOS." (See below.)
8. The console keys are "live"; see a description of their functions later.
9. The Atari logo key is disabled for normal typing. Within prompts, it acts as an "abort" key.

Since the Atari is not a dedicated word processor (that means it's not just a "word processing machine" like a Lanier, but is, rather, a general0purpose computer), it does not have special keys to activate word processing functions. Instead, the <CTRL-key> combination is used. For example, to quit the program, you would hold down <CTRL> and press <Q>. The CTRL key stands for "Control"—it is like a special shift key. The keys are linked mnemonically (easy to remember) to the commands they stand for, such as <P> for Print Text. To get a list of the commands and what they stand for at any time, just press <CTRL-?> (hold down CTRL and press the question mark) for a HELP menu. See Table 1 for a quick-reference chart of the commands.

An important feature in a word processor is block move and delete. Scriptor lets you define a series of up to 23 lines. You can then move these lines to another place in the text with Line Duplicate, or delete the defined lines with <CLEAR/D> (Erase: Defined lines). To define a block of lines, just place the cursor on the first line and press <CTRL-D>. A flashing arrow will appear to the left of the line. Press cursor-down, another symbol will appear underneath. Press cursor-down until all the desired lines have an arrow to their left. Then press <RETURN>. If you make a mistake, just try again, or press cursor-up while defining.

To copy these lines to another place, position the cursor at the place you want the lines to appear and press <CTRL-L>. If you haven't defined any lines, this command will be ignored. Note that you can press this key more than once to make many copies of the lines. You may want to delete the defined lines after you move them. Press <CLEAR>. You will see the prompt "ERASE:". Press <D>. The lines will be deleted just as if you used Delete line multiple lines.

The ESC key activates a mini-DOS. It lets you look at the directory and scratch, rename, lock, or unlock files. When you press <ESC>, you will see:

Directory,Lock,Unlock,Rename,Scratch?

Press the appropriate key. For all except the directory, you will need to enter a filename. The cursor, a half box, will be at the top of the screen. The only editing key you can use here is backspace.

Remember that you can abort any time before pressing <RETURN> by pressing the logo key. While the directory is listed, you can press <ESC> again to keep the directory on the screen while you use one of the other functions. You can also press [SELECT] (see later) to save or recall a file while looking at the directory. If you get an error message at the top of the screen, check the disk and your entry and try again.

To save or recall a document, press [SELECT]. The screen will display:

Save or Recall

Press the appropriate key, enter the filename, and the document will either be stored or retrieved. If you Recall a document, it loads starting on the line the cursor is on. This lets you add text to a document. Press START twice to home the cursor at the start of the text. If you get an error message, check to see you have the right disk, consult the DOS Manual, and try again. Remember that your filename must start with a capital letter and be followed by up to seven capital letters or numbers. You can optionally put a three-character extension on the file if you separate it with a period, for example, EDITOR. DOC, DRAFT3.CGB, DUNGEON.MAP, etc. You should not enter the "D:" prefix.

Different printers offer special print densities and formats such as boldface, underlining, super- and subscripts, double-width, condensed, proportional spacing, etc. To underline a word or phrase, enclose it in <CTRL-brackets>. In other words, <CTRL-,> is underlining on, and <CTRL-.> is underlining off. Underlining only works on the 825 printer. If you have GRAFTRAX installed in your MX-80, underlining produces italics.

The following is an advanced technique. You can define up to ten special characters and print them at any spot in your text. To define a character, set up a format line (see the discussion of format lines, below) with <CTRL-F> and enter your definitions such as 1 = 123:2 = 125:3 = 27, etc. You can then output the CHR$ code of the defined characters by embedding a caret ("^") in your text, followed by the number (for example, ^4). If you don't put a number after it, a caret will print; otherwise the character associated with the number (0-9) will be output. You can also output ASCII chaacters from within a format line with the "as" format command. For example, "as27:as18" will activate proportional spacing on the 825 printer. Use "as27:as69" for emphasized mode on the MX-80.

Since you are typing in the raw text, with no margins or line breaks, how does the computer print a nice formatted page? The computer assumes a left margin of 5, a right margin of 75, single spacing, a page length of 66, and 50 lines to be printed per page. You can change these default values with a format line.

A format line is like an embedded command line. The line starts with a format character to prevent the line from being printed out. To get the format character, press <CTRL-F>. You should get a right-pointed wedge. Then type in your commands. All commands are two lowercase letters, usually followed by a number. You can put multiple commands on the same line if you separate them with colons. For example, the following line:

will set the left margin to ten, the right margin to 70, and line spacing to two. Here is an explanation of each formatting command. Also see Table 2 for quick reference.

Note that n represents a number, with no space between the command and the number. No real error-checking is performed on the number.

asn		Sends byte n to printer.
cm:		Comment line. You can type one screen line of comments. They will not be printed to the printer. They are just for your convenience.
cnn		Centering. If n = 1, then centering will be on, and all following lines will be centered until reset by cn0. If n = 0, then centering is turned off.
fp		Forced paging. Normally, the printer will page, or go on to the next page, when the number of lines printed equals your lines per page (1p), which defaults to 50. Forced paging pages to the next page, regardless.
lmn		n = left margin, which should be less than the right margin
lnn		Prints n blank lines.
lpn		Sets lines per page to n — n should be less than the page length, to allow some blank space at the bottom of each page.
nf:filename		Will chain to next specified file, permitting a document to be split up into many parts. The nf insures that they will all print as one big file. The formatting commands carry over to each file.
pln		Sets the page length, which is almost always (and defaults to) 66.
rmn		n = right margin, which should be less than the maximum width and greater than the left margin.
spn		n = 1, single spacing; n = 2, double spacing; n = 3, triple spacing; etc.

To print your document, press . You should see:

PRINT: (C/F)

To start printing just press <RETURN>. The printer head should be positioned at about the start of the page. The C/F indicates any selected< option. C stands for Continuous Print. You would use this option with pinfeed or roll paper. It will automatically page to the start of each sheet. If you do not select continuous print, the computer will beep at the end of each page and pause. You should put in another sheet of paper and press <RETURN> to continue printing.

Note that pressing a key any other time during printing will abort the printout. The F option stands for Fast Printout. It will blank the screen during the printing, increasing printing speed better than 30 percent. Some people, however, find a blank screen disconcerting. To select one of the options, press either C or F. The appropriate letter will light up and flash. To reset the option (cancel it), press the key again. Press <RETURN> when you are ready to print the text.

The program is fairly well-structured, with separate sections for all functions. The control keys are executed via a branching IF/THEN "bucket brigade." Just patch in your own command where desired. Some functions you may want to add are block transfer (performs both block insert and block delete), Search and Replace, Insert from Disk, and simple data merge. Machine language programmers may want to try their hand at speeding up certain aspects of the program, such as Insert Line, Delete Line, and even Print Text.

Here are some other useful subroutines. GOSUB 540 returns the number of lines the user has typed (not necessarily the maximum number of lines) in EOT. GOSUB 600 clears the top line of the screen and positions the cursor at the first character, ready for a message. GOSUB 460 performs error-checking and adjustments on the X-Y position of the cursor. GOSUB 2650 returns an adjusted (uppercase if AL = 1, no cursor controls, etc.) character in A. GOSUB 2730 is a pseudo-INPUT routine that returns IN$. Variable MX controls the maximum number of characters.

TRAP 2170 will vector errors to an I/O Error message. There are two reentry points for the editor proper: GOTO 650, which clears and "refreshes" the screen, and GOTO 680, which just adjusts the cursor and continues keyboard entry (faster).

Primary variables are: CL—the pointer to the top line (from 0-#lines) of the screen; X—the horizontal position of the cursor 2-39; Y—the vertical position of the cursor on the screen, 1-23; TX$—the string that contains all the text and is organized in 38 character substrings, one for each line; T$ and T—"temporary variables"; A—usually a keystroke typed; SCR—the address of the screen memory origin; NL—number of defined lines; FRL—the starting line in text of the defined lines; RL—the starting line in TX$ for reserved lines (the buffer). Several constants are Q0, Ql, Q23—which return 0, 1, or 23 (saves memory); L2=38; L=40; B$ is 38 null (CHR$(0)) characters.

Scriptor as originally printed would not run on the model 1200XL. The modifications for the 1200XL are contained in Program 3. Simply substitute and/or add Program 3 to the main listing, Program 1.

There is another problem which might result from running Scriptor on a 1200XL. Scriptor, as mentioned before, deletes part of itself. The deletion of lines will sometimes cause Atari BASIC to lock up. Be sure to include line 7000, even though it is just a REM statement: line 7000 will help prevent the lock-up.

If Scriptor still locks up, you will have to experiment. Try adding a REM statement to the end of one of the lines at the end of the program (6000-6060). What you are trying to do is change the length of the lines being deleted.
