CHAPTER 7

FORMATTING YOUR

OUTPUT

You have probably used the tab and margin features on a typewriter. They make it easier to format the text on a page. SR-lo/15 also has tabs and margins that you can set. But it goes beyond the capabilities of a typewriter because besides having tabs that go across the page, called horizontal tabs, SR-lo/15 has verticaZ tabs that go down the page.

In this chapter we will discover how to use:

•Horizontal tabs

•Vertical tabs

•Left and right margins

USING HORIZONTAL TABS

When you turn SR-lo/15 on there are horizontal tabs set au- tomatically every eight spaces. It’s easy to use these tabs; you just send a CHR$(9) to SR-lo/15 and the print head will move to the next tab position. CHR$(9) is the ASCII code < HT > for horizontal tab.

Try this one line program to demonstrate the use of the default horizontal tabs.

10 'Tabs demo

20 LPRINT "one" CHR$(9) "two CHR$(9) "three" CHR$(9)

"four"

Here’s what will print:

onetwothree four

Even though the words are different lengths, they are spaced out evenly by the horizontal tabs.
