Description
1931-01-22 to 2013-05-21 - One of the principal developers of PL/I at IBM
Sometimes incorrectly known as PL/1, while the language is indeed named Programming Language One, the one was always meant to be expressed as a Roman numerical rather than an Arabian one, as is the tradition with computer languages even today. The Arabic 1 is only used on vintage computer and communications systems like USENET where the lower case only system or display limitation means that there is not Roman I available.
There are some variants of the language that are by now completely forgotten such as the safe variant SPL/I, that was designed at the behest of the USA department of defence in the early 1970's and was intended to be the language used for all non-business type programming done for the DoD but it end they gave up due to the variability of implementations and
PL/M
A language introduced in 1972 by Gary Kidall to allow development of computer programs for 4 and 8 bit microcomputers, full name being Programming Language for Microcomputers. Initially a very minimalistic version of PL/I that lacked even a standard I/O but later versions added features from sundry languages, which makes the latter PL/M versions somwhat unlike PL/I in many respects. Kidall sold the rights to his compiler to Intel who sold a version of the language for about 30 years mainly targeting the embedded market, but in addition he used the language to develop the CP/M operating system and used it as the main development language of Digital Research until the mid 80's. Digital released a PL/I compiler at the end of the decade for CP/M that implemented a properly defined subset of the language and that toolkit was later ported to DOS
