BASIC is an acronym for "Beginner's All-purpose Symbolic Instruction Code"

Is a family of high-level programming languages. The original BASIC was designed in 1964 by John George Kemeny and Thomas Eugene Kurtz at Dartmouth in New Hampshire, USA to provide computer access to non-science students (at the time, nearly all use of computers required writing custom software, which was something only scientists and mathematicians tended to be able to do).

The language and its variants became widespread on microcomputers in the late 1970s and 1980s.

BASIC remains popular to this day in a handful of highly modified dialects and new languages based on BASIC such as Microsoft Visual Basic.

SEGA SC-3000 has its own implementation of BASIC which was called SEGA Basic of course. As it happened in the eighties microcomputers era, every basic dialects has a common set of commands and statements, and different sound and graphic set of commands and statements depending on the machine type.

If you knew the different machines you could "translate" programs made for other computers.

We could find 3 different commands implementation of SEGA basic:

• BASIC Level II
• BASIC Level III A / Level III B
• Disk BASIC
