ends of each line. In order to make all lines of text the same length, spaces are

automatically inserted between some of the words.

If automatic justification is not required, it can be switched off by holding down

and pressing f3. Try it now and you will see the J disappear from the

top of the screen. If you now type a few lines of text, all word spacing will be

identical but lines will be of varying lengths.

Switching justification on and off is just one of the facilities you will see labelled

on the fuction key strip. VIEW has been designed in such a way that the most

frequently used commands are obtained by pressing a function key. These

functions are the ones you can see labelled along the bottom of the key strip.

The row above consists of functions called by simultaneously pressing

and a function key, and the top row facilities require simultaneous depression

of .

These are called immediate commands because they can be issued directly

from the text screen without switching to the command screen. Throughout

this chapter, immediate commands will be referenced by the key number

together with its function. For example:

+ f7 (SET MARKER)

means 'hold down SHIFT and press function key f7'.

The line of dots and asterisks along the top of the screen is called the ruler.

Amongst other things, it determines the maximum length of your lines of text.

By adjusting the ruler, you can reduce or increase the number of characters per

line for the text that follows it. Press a couple of times to leave some

space, then press:

+ f5 (RULER)

Another copy of the standard ruler will appear. Use the arrow keys to take the

cursor to the left-most end of the ruler, then erase part of the ruler by pressing

the SPACE BAR about ten times. Now enter a left margin stop >. Press

to begin a new line and type in another two or three lines of text to

observe the effect of shortening the ruler. The right-most end of the ruler can

be adusted in the same way but using the right margin stop <.

Editing a text file

The real power of a word processor lies in the facility for editing and correcting

text that has already been entered. To save time, a document called GRANTI

on which you can try out the editing facilities, is provided as part of your

Welcome software.
