 The Pascal Programming Language
In 1650, Pascal left the world of geometry and physics, and shifted his focus towards religious studies, or, as Pascal wrote, to "contemplate the greatness and the misery of man." Pascal died in Paris on August 19, 1662.
According to the Pascal Standard (ISO 7185), these goals were to a) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly and naturally reflected by the language, and b) to define a language whose implementations could be both reliable and efficient on then-available computers.
Pascal's popularity exploded in the 1970's, as it was used in writing both system and application software.

 P4
The two advances for P4 vs Pascal-S were that a larger portion of the complete Pascal language was implemented, and that defining an intermediate language and parser allowed the back end (the interpreter) to be replaced by a true code generator, and thus achieve a true compiler.
Later, UCSD Pascal was modified to include the all important "units" separate compilation facility, its own operating system, a companion Basic compiler/interpreter, and a series of graphical extensions for the language.
UCSD Pascal introduced several extensions to the language that are still in use, including units and named file handling.

Pascal requires the types and exact sizes of operands to be known before they are operated on, again leading to simplified language processing and efficient output code (although this feature has often been called a problem).
UCSD Pascal is said to be a direct ancestor to Apple Pascal, and Borland Pascal implements most of the original functions of UCSD Pascal, making it also a defacto derivative of UCSD Pascal.
In Pascal, by contrast, you must declare a string as a fixed length array: var string: packed array [1..50] of char; Which means that all of your strings must have the same length as the handler routines expect.

Indeed, in the 80's ETS declared Pascal to be the official language for their AP and GRE computer science exams -- which remained true until the late 90's.

The source to the Terak version of UCSD Pascal and P-System version I.3 (August 1977) was uploaded to CompuServe's PDP-11 Forum in July 1984 by one of the earlier UCSD licensees, Eli Willner of Pecan Software, and remains there to this day - certainly one of the oldest files still on CompuServe.

 p-System: Description, Background, Utilities
The (then UCSD) p-System is a microcomputer operating system developed starting in about 1977 (therefore before DOS, and probably before CP/M), to run, not on any physical machine in use at the time, but on a "pseudo-machine" which was emulated by an interpreter, which starts running as part of the p-System's booting.
All the rest of the system is in UCSD Pascal, compiled to the so-called "p-code" instruction set of the pseudo-machine.
UCSD Pascal is a Pascal version derived from the "P2" portable compiler of Urs Armann by the p-System project at UCSD, under Prof.

 Synthesis - Design and Research - UCSD Pascal/Java   (Site not responding. Last check: 2007-10-11)
Java's model of "run everywhere" portability and its implementation via a byte-code psuedo-machine interpreter were inspired in-part by the UCSD Pascal System - a highly portable operating system and programming environment developed under Ken Bowles' Project in the late-1970s.
By 1980, UCSD Pascal ran on essentially every available type of computer and had 10,000 users.
Later, as a principal in Volition Systems, we performed analysis and feasibility study of a Modula-2 compiler implementation for LSI-11/UCSD Pascal and Z80/CP-M. We also consulted on design of a microcoded hardware implementation of a psuedo-machine for Modula-2 and UCSD Pascal - a precursor of Sun's new MAJC chip.

 UCSD p-System Overview
The UCSD p-System was a highly portable operating system that ran programs whose object code was pseudocode for an idealized 16-bit processor.

There are obvious similarities between the UCSD p-System and Java, two attempts at portable environments separated by about 18 years.

UCSD Pascal was a specific implementation of the programming language Pascal which used the p-Code machine architecture.

It was written for a company staffed by Pascal programmers who had purchased a large C program and wanted to understand it.
The heavy use, where possible, of Turbo Pascal specific features occurred for two reasons, 1) it gave a higher rate of perfect translation and 2) for commercial reasons we did not want the output of this translator being fed into other Pascal compilers, we wanted to sell copies of our C to ISO Pascal translator.
Because of the close connection between the ANSI C compiler and C to Pascal translator it was possible for one to make use of code written for the other.
