vital Beginner 's All -purpose Symbolic Instruction Code .
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 .
