( Chem.) ( a) Relating to a base; performing the office of a base in a salt. ( b) Having the base in excess, or the amount of the base atomically greater than that of the acid, or exceeding in proportion that of the related neutral salt. ( c) Apparently alkaline, as certain normal salts which exhibit alkaline reactions with test paper. [ 1913 Webster] 2. ( Min.) Said of crystalline rocks which contain a relatively low percentage of silica, as basalt. [ 1913 Webster] { Basic salt} ( Chem.), a salt formed from a base or hydroxide by the partial replacement of its hydrogen by a negative or acid element or radical. [ 1913 Webster]
BASIC \ BASIC\ n. 1. ( Computers) [ Beginner' s All- purpose Symbolic Iruction C.] an artificial computer language with a relatively simplified instruction set. Note: Writing a program in BASIC or other higher computer languages is simpler than writing in assembly language. See also { programming language}, { FORTRAN}. [ PJC]
higher programming language \ higher programming language\ n. ( Computers) A computer programming language with an instruction set allowing one instruction to code for several assembly language instructions. Note: The aggregation of several assembly- language instructions into one instruction allows much greater efficiency in writing computer programs. Most programs are now written in some higher programming language, such as { BASIC}, { FORTRAN}, { COBOL}, { C}, { C}, { PROLOG}, or { JAVA}.

A simple language originally designed for ease of programming
by students and beginners. Many dialects exist, and BASIC is
popular on {microcomputers} with sound and graphics support.
Most micro versions are {interactive} and {interpreted}.
BASIC has become the leading cause of brain-damage in
proto-hackers. This is another case (like {Pascal}) of the
cascading lossage that happens when a language deliberately
designed as an educational toy gets taken too seriously. A
novice can write short BASIC programs (on the order of 10-20
lines) very easily; writing anything longer is painful and
encourages bad habits that will make it harder to use more
powerful languages. This wouldn't be so bad if historical
accidents hadn't made BASIC so common on low-end micros. As
it is, it ruins thousands of potential wizards a year.
Originally, all references to code, both {GOTO} and GOSUB
(subroutine call) referred to the destination by its line
number. This allowed for very simple editing in the days
before {text editors} were considered essential. Just typing
the line number deleted the line and to edit a line you just
typed the new line with the same number. Programs were
typically numbered in steps of ten to allow for insertions.
Later versions, such as {BASIC V}, allow {GOTO}-less
{structured programming} with named {procedures} and
{functions}, IF-THEN-ELSE-ENDIF constructs and {WHILE} loops
etc.
Early BASICs had no graphic operations except with graphic
characters. In the 1970s BASIC {interpreters} became standard
features in {mainframes} and {minicomputers}. Some versions
included {matrix} operations as language {primitives}.
A {public domain} {interpreter} for a mixture of {DEC}'s
{MU-Basic} and {Microsoft Basic} is {here
(ftp://oak.oakland.edu/pub/Unix-c/languages/basic/basic.tar-z)}.
A {yacc} {parser} and {interpreter} were in the
comp.sources.unix archives volume 2.
See also {ANSI Minimal BASIC}, {bournebasic}, {bwBASIC},
{ubasic}, {Visual Basic}.
