Pascal (programming language): Difference between revisions

Procedures and functions: Although the example actually does not contain an output statement, the name ("printing") strongly implies it. Thus I have placed the required output file in the header.

Line 90:
Pascal-P5, created outside the Zürich group, accepts the full Pascal language and includes ISO 7185 compatibility.
 
Pascal-P6 is a follow on to Pascal-P6P5 that along with other features, aims to be a compiler for specific CPUs, including AMD64.
 
[[UCSD Pascal]] branched off Pascal-P2, where [[Kenneth Bowles]] used it to create the [[Interpreter (computing)|interpretive]] UCSD p-System. It was one of three operating systems available at the launch of the original [[IBM Personal Computer]].<ref>[http://www.cbi.umn.edu/oh/pdf/oh392jb.pdf cbi.umn.edu], "An Interview with John Brackett and Doug Ross"{{dead link |date=March 2018 |bot=InternetArchiveBot |fix-attempted=yes}}, p15, Charles Babbage Institute, 2004</ref> UCSD Pascal used an intermediate code based on byte values, and thus was one of the earliest ''[[bytecode]] compilers''. [[Apple Pascal]] was released in 1979 for the Apple 2 and Apple 3 computer systems. It was an implementation of, or largely based on, UCSD Pascal. Pascal-P1 through Pascal-P4 was not, but rather based on the CDC 6600 60-bit word length.
