Formatting Your Output; Using Horizontal Tabs - Star Micronics SG-10 User Manual

CHAPTER 7
I 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.
SG-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, SG-lo/15
has vertical tabs that go down the page.
In this chapter we will discover how to use:
l
Horizontal tabs
l
Vertical tabs
l
Left and right margins

USING HORIZONTAL TABS
When you turn SG-10/15 on there are horizontal tabs set au-
tomatically every eight spaces. It's easy to use these tabs; you
just send a CHR$(9) to SG-IO/15 and the print head will move
to the next tab position. CHR$(9) is the ASCII code < HT>
for horizontal tab.
Try this one line program to demonstrate the use of the default
horizontal tabs.

Here's what will print:

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