Release date: 
Wednesday, 8 November, 2017



Authors/Port authors:

Compiler for the PL/I programming language, although it is currently missing some features.

PL/I is a powerful programming language suitable for a wide range of problems. PL/I has been used to write operating systems and compilers, simulations, real-time programs, mathematical software, spreadsheets, GUI programs, business applications, and much more.

 PL/I is a more secure programming language.

  • Karger and Schell, in their retrospective on Multics Security say:

    “a PL/I programmer would have to work very hard to program a buffer overflow error, while a C programmer has to work very hard to avoid programming a buffer overflow error.”

  • PL/I is widely used on mainframes and midrange systems today, but since the demise of Digital Research, Inc. has not been readily available on personal computers.

    Ian Hayes of Clarity Consulting says:

    “PL/I is heavily used by about 25 percent of all IS organizations around the world, and many additional organizations have at least several mission-critical PL/I applications.”
