BASIC Language
A computer will remind you of a complicated and difficult
machine. However, a regularly used small calculator is a type of
computer, and its principle is essentially the same as a large
computer. A major difference between a calculator and computers
like the PC-8201 is that the calculator is usually limited in the kind
of tasks it can perform.
A typical computer, as well as the PC-8201, can perform various
operations and more sophisticated tasks. For example, it can
execute a complicated calculation, create graphics, animate graphics,
produce sound, etc.
To execute such varied functions and tasks, words (special language)
are needed to direct commands and precise instructions to the
computer. However, the computer cannot understand our human
language.
Languages have been developed for the purpose of transmitting
commands or instructions to the computer. One of the most
common of the languages is called "BASIC", meaning "Beginner's
All-purpose Symbolic Instruction Code".
The BASIC language that the PC-8201 uses is N 8 2 -BASIC. This
programming language is easy to use and has the following advan¬
