pascal n. an algol-descended language designed by niklaus wirth on the
cdc 6600 around 1967-68 as an instructional tool for elementary
programming. this language, designed primarily to keep students from
shooting themselves in the foot and thus extremely restrictive from a
general-purpose-programming point of view, was later promoted as a
general-purpose tool and, in fact, became the ancestor of a large family
of languages including modula-2 and ada see also
bondage-and-discipline language. the hackish point of view on pascal
was probably best summed up by a devastating and, in its deadpan way,
screamingly funny 1981 paper by brian kernighan of kr fame
entitled "why pascal is not my favorite programming language", which was
turned down by the technical journals but circulated widely via
photocopies. it was eventually published in "comparing and assessing
programming languages", edited by alan feuer and narain gehani
prentice-hall, 1984. part of his discussion is worth repeating here,
because its criticisms are still apposite to pascal itself after many
years of improvement and could also stand as an indictment of many other
bondage-and-discipline languages. the entire essay is available at
`http://www.lysator.liu.se/c/bwk-on-pascal.html'. at the end of a
summary of the case against pascal, kernighan wrote:
9. there is no escape
this last point is perhaps the most important. the language is
inadequate but circumscribed, because there is no way to escape its
limitations. there are no casts to disable the type-checking when
necessary. there is no way to replace the defective run-time
environment with a sensible one, unless one controls the compiler
that defines the "standard procedures". the language is closed.
people who use pascal for serious programming fall into a fatal
trap. because the language is impotent, it must be extended. but
each group extends pascal in its own direction, to make it look
like whatever language they really want. extensions for separate
compilation, fortran-like common, string data types, internal
static variables, initialization, octal numbers, bit operators,
etc., all add to the utility of the language for one group but
destroy its portability to others.
i feel that it is a mistake to use pascal for anything much beyond
its original target. in its pure form, pascal is a toy language,
suitable for teaching but not for real programming.
pascal has since been entirely displaced mainly by c from the
niches it had acquired in serious applications and systems programming,
and from its role as a teaching language by java.

pascal
after the french mathematician blaise pascal
1623-1662 a programming language designed by niklaus
wirth around 1970. pascal was designed for simplicity and
for teaching programming, in reaction to the complexity of
algol 68. it emphasises structured programming
constructs, data structures and strong typing. innovations
included enumeration types, subranges, sets, variant
records, and the case statement. pascal has been extremely
influential in programming language design and has a great
number of variants and descendants.
ansi/ieee770x3.97-1993 is very similar to iso pascal but
does not include conformant arrays.
iso 7185-1983e. level 0 and level 1. changes from jensen
wirth's pascal include name equivalence; names must be bound
before they are used; loop index must be local to the
procedure; formal procedure parameters must include their
arguments; conformant array schemas.
