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.
The system supports full 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.

Basic usage examples are provided for the Pascal components
Errors commonly encountered in these programs are discussed.
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.

In section 1 we give sources of information about

Section 4 describes input/output with special attention given to features

History of the implementation
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.
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.
