A better analogy is a car with automatic transmission: you can shift to Drive or Reverse after starting the engine, but you always start the engine in Park. Similarly, in WDRDWRITER, there are several condtions which you can change after you turn on the program, but the conditions always come on in the same way:
[[File:Wordwriter - Definitions.png|center|600px]]
====Line Numbers====
WORDWRITER comes on without showing line numbers. If you key in FCTN O line numbers 0001 through 0024 will appear down the left side of the screen. If you key in FCTN D again they will disappear. You can make the numbers appear and disappear in this way as often as you like. The numbers are useful, telling you how long your file is. You also need the line numbers when you tell WORDWRITER to Move or Copy a group of lines from one location to another.
The TV screen shows 40 columns of text ACROSS, except when the line numbers are on. Then you can only see 34 columns of text across because the line numbers down the left side of the screen take up 6 positions (4 digits & 2 spaces). When you key in FCTN D again, the line numbers vanish and you can once again see 40 columns across.
====Line Numbers====
Key FCTN O to show the column of four digit line numbers along the left side of the screen. FCTN Dis an on/off switch. When you key it again the line numbers vanish. With the line numbers on you will see that you cannot make the cursor go higher than line 0001. The lowest you can move the cursor is to the line above End of Document. If you continue moving the cursor downwards new blank lines will be created.
MARGINS
You can set margins directly (CTRL t) or with the MASTER PROMPT
LINE (FCTN = or FCTN 9). I recommend CTRL t. Hold down the CTRL
key with your left thumb while simultaneously keying the t. It
makes no difference if you use lower case t or upper case T. As
soon as you do this a column of four digit line numbers appears
down the left side of the screen. The top row of the screen
(beginning with "Tabs") lists 1 through 9, space, 1 through 9,
etc. The second line across the screen has an L (left margin)
under the 1, and I (indentation) under the 5, then a series of T's
ttab stops) under the 5 1 s and 1D's places. Your TV screen shows
•ip to column 34. To see 35 through 80 you must move your cursor
.ight.
MARGINS, INDENTATION, AND TABS
When you key in CTRL t the top line of the screen will display
column numbers 1 through 34. At the same time, the line numbers
<div id="mp-tfp" style="margin:0.1em 0.4em 0.6em;"></div>
