If you own a C-64, you The one you purchased. And the GEOS realizes the technical potential that has been in the

C-64 all along. Speed. Power. Ease of use. Sophisti cation. Elegant, practical

applications you might

expect of a high-end personal computer, all made possible with GEOS. It's so simple— but then, so was fire. Once it caught on. To begin at the beginning. GEOS stands for GRAPHIC ENVIRONMENT OPERATING SYSTEM. Why?

GEOS can be divided into 4 areas: two functional aspects {deskTop and Desk Accessories), and two major applications

(geoPaint and geoWrite). deskTop. deskTop is a graphic interface, making file organization and manage ment easy. As always, you call the shots. Load a disk. Files appear as icons on the

disk notepad; to flip through, point at the folded corner and click. Prefer a file appear on a different sheet? Move it. It's easy.

GRAPHIC: Because menus and icons replace long, typed command lines. Point and click, that's it.

I5i K twtes us«d

; .■.,

ENVIRONMENT: Because GEOS provides a consistent, powerful way to use your computer. Learning new applications is a

snap (or should we say click). OPERATING SYSTEM: Because GEOS orchestrates every function so that they all work together systematically, even symphonically.

Some basics. Icons are graphic images which represent files or utilities. Each is

different, and all are easy to recognize and easy to use.

A menu is just that: a list of functions availa ble for selection. When a menu appears, move the pointer to any item you wish. Click. Click. You're on your way. A pointer is used to select and activate items. To move the pointer, roll the mouse or trackball or rotate the joystick. Once on target, click once to select; click a second time to activate. Fonts are a new way of looking at text. Choose from 5 different fonts (with more on the way). Try ffitoinfiir, or Roma, bold, or italics, even underline and . . Need to fit more words on a line? Pick a smaller point size, like univaatycpoim, and get over one hundred characters per line. All this and fast too. Because the integrated diskTurbo software improves 1541 disk drive

performance 5 to 7 times. That's right. On both reads and writes.

Create a new document or re-name an existing one. Want to copy a file onto the same or a different disk? Fine. Forgotten

what a file contains? Select "get info" from the file menu. A description of that file's

contents appears. Finished with a file? Print it. Save it. Or drop it in the trash and have done with it. Your call. geoPaint. A full-featured, color graphics workshop at your fingertips. The pointer operates any one of the

fourteen graphic tools and shapes in the drawing menu. Create masterpieces on the Drawing Window. By turns, use a pencil, an airbrush or a paint brush, each with a character all its own. Draw straight lines, squares, rectang les or circles. Fill in with any of the 32

patterns. Switch to pixel-mode, where each dot in a selected section is magnified many times its size for easy manipulation.

appear off the printer. Typists will appreciate tabs, word-wrap and page breaks. Documents may contain up to 64 pages. What's more, you can move to any page instantly. If you like, you can cut selected

text from one section and move or copy it to another. Add graphics from geoPaint. It's a cinch.

Second thoughts? Erase what you don't want. Or "UNDO" your last act. (If only life could imitate art!) Add text if you like, in different fonts, styles or point sizes. Even change its position or layout at will. Move or copy any part of your creation. Once done, you can include your artwork in

These include an alarm clock, a notepad for reminders, a four-function calculator, and photo and text albums which store pictures and phrases you may then paste into applications.

In addition to providing data on past performance of In vestments, Vestor can also predict the future performance of stocks and generate lists of from 10 to 100 of the top- and

lowest-ranked stocks based on thdr Investnieni Strategy Hal ing ( isr). The ISK is a theoretical prediction ofthe percentage that a stock will appreciate or depredate over the next (> to

24 months, based on a combined fundamental and technical rating.

One of tlie most welcome features of Vestor is that it is menu-driven and, therefore, fast and easy to use. The main menu is divided into six sections, each containing from four to nine individual programs! .Stocks, Options, Futures, Aver

The most commonly used program in Vestor's Slocks area is called Evaluate, As its name implies, this program helps you

to evaluate selected stocks and portfolios by providing a de tailed report that includes performance predictions, ratings, and buy/sdU Signals, as well as standard Information such as

price/earnings ratio, annual dividend, and yield. Noi only will the Evaluate program give you iliis type of data on individual Stocks, it also combines projected data on all the slocks you evaluate to forecast the overall gain or loss on your portfolio over the next 6 to 2i months.

Biorhythm for the Commodore 64 XL\cryonc has had good days ;uicl bad days, Hut have you ever wondered why

certain days arc so much better (or worse) than others? Research done by Dr. Wllhelm l-lciss of Berlin, Professor Herman Swoboda of the University of Vienna, and by Alfred Tdtschtr of Austria carl}1 in this century,

produced the theory known as biorhythm, or blo-mathemadcs, which held that man's natural cycles full imo three groupings, which they Labeled 'physical,'' emotional," and "Intellectual/

According to the theory, these cycles arc generated by the natural rhythms of

your body and can he measured with regularity throughout your life. They

have nothing to do with astrology, or any other mystic art, but Instead are based on

scientific research and statistics. iliu "physical" rhythm makes a com

plete cycle every 2.1 days and affects your physical strength, endurance, ener gy, and your resistance to illness, it also

measures your confidence, coordination, siainina, and general well-being

'llic first half of the cycle (11W days) are [lie days when a person feels vigor

ous and wlien his or her endurance is at Its best The second half of the cycle is ;i

recharging period During these days a person may tire more easily. This second

period should by no means ix- consid ered bad in fact, this period can haw ad vantages.

The two important points in this cycle are the first day and the halfway mark

(when the cycle is switching from high to low). These are the "critical days." Which I will explain later.

Whenever a cycle crosses the cenier (X) line, you have a critical day. This means that your body, which is afleeted by certain neurological, chemical, and
