CHANGE/ a / the /

Switch to the text screen and observe the effect.

You can apply CHANGE to phrases as well as single words. For example:

CHANGE/ insect / small invertebrate segmented animal /

The slash (/) in a CHANGE command is known as a delimiter because its

function is to mark the beginning and end of a word or phrase. A space may be

used instead of a slash provided no other spaces are required in the command.

For example:

CHANGE kangaroo wallaby

As a diversion, readers may like to use CHANGE on single characters in order

to decode the following passage. Despite its appearance, only five CHANGE

operations are necessary!

The CHANGE operation is just one of a group of global operations that provide

very powerful editing facilities. Treatment of more advanced techniques is

outside the scope of this introduction and users are advised to consult the

VIEW User Guide.

More on rulers

Clear any text that you have typed in by switching to the command screen and

typing:

NEW

If you are not already in mode 131 (shown as 'Mode 3' at the top of the

command screen), type:

MODE 131

Press to switch to the text screen.

As you saw earlier, the state of the text ruler determines the maximum line

length for the text below it. The ruler at the top of the current screen is the

standard ruler for mode 131 and it corresponds to a line length of 74 characters.

Each mode has its own standard ruler and that for mode 135, for example,

corresponds to a line length of 34 characters.

Put another standard ruler on the screen by pressing:

+ f5 (RULER)
