Berkeley
|
|
Pascal
|
|
is designed for interactive instructional use
|
|
and runs on the \s-2PDP\s0/11 and \s-2VAX\s0/11 computers.
|
|
Interpretive code is produced,
|
|
providing fast translation at the expense of slower execution speed.
|
|
There is also a fully compatible compiler for the \s-2VAX\s0/11.
|
|
An execution profiler and
|
|
Wirth's cross reference program are also
|
|
available with the system.
|
|
.PP
|
|
The system supports full Pascal.
|
|
The language accepted is
|
|
`standard' Pascal,
|
|
and a small number of extensions.
|
|
There is an option to suppress the extensions.
|
|
The extensions include a separate compilation facility
|
|
and the ability to link to object modules
|
|
produced from other source languages.

system, the Pascal language, and the

system.

Details are given of special considerations due to the

interactive implementation.
|

A number of examples are provided including many dealing with

input/output. An appendix supplements Wirth's

to form the full definition of the Berkeley implementation of the language.

Introduction
|
|
.PP
|
|
The
|
|
.UP
|
|
.UM
|
|
consists of five major sections and an appendix.
|
|
In section 1 we give sources of information about
|
|
.UX ,
|
|
about the programming
|
|
language Pascal, and about the
|
|
Berkeley
|
|
implementation of the language.
|
|
Section 2 introduces the
|
|
Berkeley
|
|
implementation and provides a number of tutorial examples.
|
|
Section 3 discusses the error diagnostics produced by the translators
|
|
.PC
|
|
and
|
|
.PI ,
|
|
and the runtime interpreter
|
|
.X .
|
|
Section 4 describes input/output with special attention given to features
|
|
of the interactive implementation and to features unique to
|
|
.UX .
|
|
Section 5 gives details on the components of the system
|
|
and explanation of all relevant options.
|
|
The
|
|
.UM
|
|
concludes with an appendix to Wirth's
|
|
.I "Pascal Report"
|
|
with which it forms a precise definition of the implementation.
|
|

|
|
History of the implementation
|
|
.PP
|
|
The first
|
|
Berkeley
|
|
system was written by Ken Thompson in early 1976.
|
|
The main features of the present system were implemented by
|
|
Charles Haley and William Joy during the latter half of 1976.
|
|
Earlier versions of this system have been in use since January, 1977.
|
|
.PP
|
|
The system was moved to the \s-2VAX\s0-11
|
|
by Peter Kessler and Kirk McKusick
|
|
with the porting of the interpreter in the spring of 1979,
|
|
and the implementation of the compiler in the summer of 1980.
