This is the 5th version of the Pascal-P compiler from Zurich. This is the Pascal-P4 compiler modified to be ISO 7185 Pascal compilant, both in the the implementation language, and in the language it processes.
Pascal-P was an implementation kit, created between 1972 and 1974, for the original language Pascal. The source for the original compiler was passed around and modified quite a bit, but Niklaus Wirth noted that it was very popular, and represented a good method to popularize the language. He gathered the source into a clean version called Pascal-P2. The Zurich group then created an improved version called Pascal-P4.
You can find all of the Pascal-P versions here in sourceforge:
