CHAPTER 7

FORMATTING YOUR

L.

OUTPUT

:I*. -

You have probably used the tab and margm features on a typewriter. They make it easier to format the text on a page. SD-lOi15 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, SD-lo/l5 has vertical 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 SD-lo/l 5 on there are horizontal tabs set au- tomatically every eight spaces. It’s easy to use these tabs; you just send a CHR$(9) to SD- lo/15 and the print head will move to the next tab position. CHR$(9) is the ASCII code <HT> for horizontal tab.

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

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