There is an ANSI standard for PL/I dating from the late 1960s.
In the 1970s, ANSI published a subset standard for use on
minicomputers which eliminated the lesser-used and hard-to-
implement parts of the full standard.

PL/I was implemented by a number of manufacturers. I have
used it on a Univac 1110 mainframe and Data General
minicomputers. There were several versions available for the
IBM PC, but I don't know if any are still supported.
