Much of the AIX v2 kernel was written in the PL / I programming language, which proved troublesome during the migration to AIX v3.

When Marinchip Software Partners ( later known as Autodesk ) formed, the founders decided to re-code Interact in C and PL / 1.

In the end, the PL / 1 version was unsuccessful.

There is third party support for PL / SQL in Berkeley DB via a commercial product named Metatranz StepSqlite.

With Dhrystone, Weicker gathered meta-data from a broad range of software, including programs written in FORTRAN, PL / 1, SAL, ALGOL 68, and Pascal.

* PL / SQL

Intel lent him systems using the 8008 and 8080 processors, and in 1973, he developed the first high-level programming language for microprocessors, called PL / M.

He demonstrated CP / M to Intel, but Intel had little interest and chose to market PL / M instead.

Dorothy might have believed that the company could not deliver CP / M-86 on IBM's proposed schedule, as the company was busy developing an implementation of the PL / I programming language for Data General.

Instructions directly supporting nested ALGOL-family languages such as Pascal and PL / M were also added.

The MVS core was almost entirely written in Assembler XF, although a few modules were written in PL / S, but not the performance-sensitive ones, in particular not the Input / Output Supervisor ( IOS ).

It was written PL / 1 by Honeywell for the Multics operating system and first sold in June 1976.

Macros in the PL / I language are written in a subset of PL / I itself: the compiler executes " preprocessor statements " at compilation time, and the output of this execution forms part of the code that is compiled.

He designed the simple programming language PL / 0 to illustrate compiler design.

Modula-2, Ada, and ML all developed notable module systems in the 1980s, although other languages, such as PL / I, already had extensive support for modular programming.

PL / I (" Programming Language One ", pronounced " pee-el-one ") is a procedural, imperative computer programming language designed for scientific, engineering, business and systems programming applications.

PL / I's principal domains are data processing, numerical computation, scientific computing, and systems programming ; it supports recursion, structured programming, linked data structure handling, fixed-point, floating-point, complex, character string handling, and bit string handling.

replaced briefly by MPPL ( MultiPurpose Programming Language ) and, in 1965, with PL / I ( with a Roman numeral “ I ” ).

PL / I language was vested initially in the New York Programming Center and later at the IBM UK Laboratory at Hursley.

language and had a role in IBM ’ s process for controlling the language through their PL / I Projects.

The experience of defining such a large language showed the need for a formal definition of PL / I.

The language was first specified in detail in the manual “ PL / I Language Specifications.

written in New York from 1965 and superseded by “ PL / I Language Specifications.

IBM continued to develop PL / I in the late sixties and early seventies,

The Standard for PL / I was approved in 1976.

The additional goals for PL / I were:

To meet these goals PL / I borrowed ideas from contemporary languages while adding substantial new capabilities and casting it with a distinctive concise and readable syntax.

PL / I passes Donald Knuth's man or boy test.

New attributes, statements and statement options could be added to PL / I without invalidating existing programs.

The summary is extracted from ANSI PL / I Standard.

and the ANSI PL / I General-Purpose Subset Standard < Ref name =" SubsetG " />.

A PL / I program consists of a set of procedures, each of which is written as a sequence of statements.

It won out over numerous other suggestions because it was the name of the Roman god of the underworld, who was able to render himself invisible, and because Percival Lowell's initials PL formed the first 2 letters.

It was later implemented on Multics using PL / I.

The bracket notation "" was introduced a few years later in IBM's PL / I definition but is now universally recognised.

The Delta and Pine Land Company intended to commercialize the technology, but D & PL was acquired by Monsanto in 2007.

So Meta-IV, was " used to define major portions of " the PL / I programming language.

A classic work on the subject was The Elements of Programming Style, written in the 1970s, and illustrated with examples from the Fortran and PL / I languages prevalent at the time.

The implementation was written in PL / 360, an ALGOL-like assembly language designed by Wirth.

Gail believed there was an organized conspiracy to belittle his learning and professional success, and there was a feud between him and his literary opponents, the most distinguished of whom was PL Courier.

The game was also ported to Prime Computer's super-mini running PRIMOS in the late 1970s, utilising FORTRAN IV, and to IBM mainframes running VM / CMS in late 1978, utilizing PL / I.

Although the work was focused on COBOL, the idea of a host-language independent database was starting to emerge, prompted by IBM's advocacy of PL / I as a COBOL replacement.

It is based on IBM's PL / I language, and was designed in the early 1970s.

IBM attempted to turn away from assembly language to higher level languages as early as 1965, and was making substantial use of PL / S by 1969, e. g. in MVS.
