If we use a ";" instead of a comma, the next value will be printed immediately following the previous value.

NOTE

Numbers are always printed with at least one trailing space. Any text to be printed must always be enclosed in double quotes.

Try the following examples:

1.PRINT "ONE HALF EQUALS"; 1/2

ONE HALF EQUALS .5

2.PRINT 1,2,3

12

...

3.PRINT 1;2;3

12 3

4.PRINT -1;2;-3 -1 2 -3

205 NUMBER FORMAT

We will digress for a moment to explain the format of numbers in BASIC. Numbers are stored internally to over nine digits of accuracy. When a number is printed, only nine digits are shown. Every number may also have an exponent (a power of ten scaling factor).

The largest number that may be presented in AIM 65 BASIC is 1.70141183*10^38, while the smallest positive number is 2.93873588*10^-39.

When a number is printed, the following rules define the format:

1.If the number is negative, a minus sign (-) is printed. If the number is positive, a space is printed.

2.If the absolute value of the number is an integer in the range 0 to 999999999, it is printed as an integer.

3.If the absolute value of the number is greater than or equal to 0.01 and less than or equal to 999999999, it is printed in fixed point notation, with no exponent.

4.If the number does not fall under categories 2 or 3, scientific notation is used.

Scientific notation is formatted as follows: SX.XXXXXXXXESTT. (Each X is some integer, 0 to 9.)

The leading "S" is the sign of the number: a space for a positive number and a "-" for for a negative one. One non-zero digit is printed before the decimal point. This it followed by the decimal point and then the other eight digits of the mantissa. An

"E" is then printed (for exponent), followed by the sign (S) of the exponent; then the two digits (TT) of the exponent itself. Leading zeroes are never printed; i.e.,

the digit before the decimal is never zero. Trailing zeroes are never printed. If there is only one digit to print after all trailing zeroes are suppressed, no decimal point is printed. The exponent sign will be "+" for positive and "-" for negative. Two

digits of the exponent are always printed; that is, zeroes are not suppressed in the exponent field. The value of any number expressed thus is the number so the left of the "E" times 10 raised to the power of the number to the right of the "E".

Regardless of what format is used, a space is always printed following a number. BASIC checks

to see if the entire number will fit on the current line. If it cannot, a carriage return/line feed is executed before printing the number.

Following are examples of various numbers and the output format in which BASIC will output them:

II specifications

The Apple II, launched in April 1977, was one of the first highly successful mass-produced microcomputer products. It marked a significant leap in personal computing, setting standards for future developments in the industry. Created by Steve Wozniak and Steve Jobs, the Apple II differentiated itself with its user-friendly design, appealing aesthetics, and robust capabilities.

One of the standout features of the Apple II was its open architecture, which allowed users to expand and enhance the computer's functionality. This design enabled hundreds of third-party hardware and software developers to contribute to its ecosystem, resulting in an array of peripherals, including printers, modems, and storage devices. The Apple II utilized a MOS Technology 6502 microprocessor running at a clock speed of 1 MHz. Initially equipped with 4 KB of RAM, the machine could be expanded to 48 KB, accommodating more complex applications and programs.

The Apple II was also notable for its colorful graphics. It was one of the first computers to support color display, offering a 6-color palette with a resolution of 280x192 pixels in 16 colors when using its Color Graphics Card. This feature significantly enhanced the visual appeal of games and educational software developed for the platform, making computing more accessible and entertaining for various audiences.

Apple's commitment to user experience was evident in the design of the machine. It featured an integrated keyboard and a plastic case, which was both durable and visually appealing. The self-contained design included drive bays for floppy disk drives, allowing for quicker data access than traditional tape drives. It also supported audio output, enabling sound effects and music, a novelty at the time.

The introduction of the Apple DOS operating system further underscored the machine's capabilities. DOS streamlined file management and made it easier for users to navigate and manage their data. The combination of hardware and software positioned the Apple II as an educational tool and a gaming platform, fostering a vibrant software ecosystem.

The Apple II family continued to evolve, with variations like the Apple II+, IIe, and IIgs being introduced over the years. These iterations brought enhancements in memory, processing power, and graphics capabilities. The legacy of the Apple II endures, not only as a foundational product in personal computing but also as a symbol of innovation that paved the way for future advancements in technology. Its impact is still felt today, as it inspired countless developers and shaped the trajectory of the computer industry.
