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.

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.

* PL / I ( NPL ) was designed in the early 1960s to incorporate the best ideas from FORTRAN and COBOL.

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 ” ).

In addition to an 8080 / 8085 assembler, Intel produced a number of compilers including PL / M-80 and Pascal languages, and a set of tools for linking and statically locating programs to enable them to be burnt into EPROMs and used in embedded systems.

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

Programming languages available for the AS / 400 include RPG, assembly language, C, C ++, Pascal, Java, EGL, Perl, Smalltalk, COBOL, SQL, BASIC, PHP, PL / I, Python and REXX.

* PL / I ( Programming Language One )-a hybrid commercial / scientific general purpose language supporting pointers.

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.

Programming Language for Business or PL / B is a business-oriented programming language originally called DATABUS and designed by Datapoint in the early 1970s as an alternative to COBOL because Datapoint's 8-bit computers could not fit COBOL into their limited memory, and because COBOL did not at the time have facilities to deal with Datapoint's built-in keyboard and screen.

PL / S, short for Programming Language / Systems, is a " machine-oriented " programming language based on PL / I.

PL / S was succeeded by PL / S II and PL / AS ( Programming Language / Advanced Systems ), and then PL / X ( Programming Language / Cross Systems ).

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.

Distributions will often contain installation scripts ( usually called Makefile. PL or Build. PL ) and test scripts which can be run to verify the contents of the distribution are functioning properly.

* Aerauto PL. 5C – early 1950s

Passed in 1953, Public Law 280 ( PL 280 ) gave jurisdiction over criminal offenses involving Indians in Indian Country to certain States and allowed other States to assume jurisdiction.

Some PL 280 reservations have experienced jurisdictional confusion, tribal discontent, and litigation, compounded by the lack of data on crime rates and law enforcement response.

In microcomputers, SWTPC's 6800 and 6809 machines used TSC's FLEX disk operating system, Radio Shack's TRS-80 machines used TRS-DOS, their Color Computer used OS-9, and most of the Intel 8080 based machines from IMSAI, MITS ( makers of the legendary Altair 8800 ), Cromemco, North Star, etc., used the CP / M-80 disk operating system.

Examples include the German Marder and Puma, the Chinese ZBD-97, the Soviet / Russian BMP-3, the Indian Abhay IFV, the Yugoslavian BVP M-80, the Canadian LAV III, the British Warrior, the American M2 Bradley, the Spanish Pizarro / ASCOD, the Italian Dardo, the South African Ratel, the French AMX-10P and VBCI, the Swedish Combat Vehicle 90 and the Dutch YPR-765 AIFV.

The most important of the early OSes on these machines was Digital Research's CP / M-80 for the 8080 / 8085 / Z-80 CPUs.

MS-DOS, or PC-DOS when supplied by IBM, was based originally on CP / M-80.

) for any of the platforms CP / M-80, CP / M-86 and MS-DOS ( NEC APC-III ) would run on, a task that would otherwise require considerable effort to port due to the large differences in graphics hardware ( and concepts ) between the various systems of that era.

The commands are those of CP / M-80.

There was a V2080 CPMulator program which allowed to run 8080-based CP / M-80 programs on a MS-DOS machine.

It was also the name of an older luggable computer from the early 1980s, distinguished by being able to run both the MS-DOS and CP / M-80 operating systems.

For reference, a typical stick of dynamite contains over 10 times more explosive material than an M-80 ( 35 grams of nitroglycerin versus 3 grams, typically of chlorate / sulfur powder ).

The name was short for Roland Perry's EDitor, the program being put together quickly by Roland Perry, the Amstrad executive running the computer product development, when it was realised that CP / M-80 came with no usable full-screen editor, but users had a requirement to edit configuration files.

The Epson QX-10 is a microcomputer running CP / M or TPM-III ( CP / M-80 compatible ) which was introduced in 1983.

The Seequa Chameleon was an early 1980s luggable personal computer ; it was capable of running both the DOS and CP / M-80 operating systems.

The Actrix computer, released in 1984 by Actrix Computer Corporation, was a Zilog Z80-based transportable personal computer running CP / M-80 V2. 2.
