If you place that piece of paper on any page in this book, it will
cover up all but a small portion of the page. Yet by moving that
window horizontally and vertically, you can bring any desired por-
tion of the page into view:
Moving the window does not change what’s on the page. It just
changes what’s in the window. The text on the page is still there,
whether you can see it or not.
In addition to letting you view any desired portion of the virtual
screen, the screen editor will let you place words, numbers and
character graphics on the virtual screen, and make it easy for you to
insert and delete text at any point.
Turn on your HX-20 now and select BASIC from the menu. You
won’t actually learn any BASIC programming in the following
pages, but you must enter BASIC in order to learn how to use the
screen editor.
The
cursor
When you select BASIC from the menu, a message will appear on
the screen. For now, ignore that message.
