'''NORD PL''' ('''NORD''' '''P'''rogramming '''L'''anguage, or '''''NPL''''' ) is a programming language from [[Norsk Data]]. It shipped as a standard component of the operating system [[SINTRAN III]]. It could also run freestanding, or under [[NORD-TSS]].

The language was also used to implement SINTRAN III. The NORD PL compiler was also written in NORD PL and some core applications was early on written in NORD PL until [[PLANC]] came and linker and other software was rewritten in PLANC.

A quote from the NORD PL Users Guide, July 77, "important advice to the NORD PL programmer":

''NORD PL is not a problem oriented high level language like FORTRAN or COBOL. It is a machine oriented medium level language introduced to simplify the assembly coding, i.e., in any statement written the programmer should call attention to the influence oon the register contents!''

The NORD PL compiler produced [[MAC]] assembly code which then had to be assembled using the [[MAC]] assembler. The syntax resembles [[wikipedia:ALGOL|ALGOL]], but it was used like an assembler because all instructions, addressing modes, registers, and memory could be accessed from the language. Compared to writing assembly (MAC) directly, the intention was to make it easier to write code and to improve error checking and readability. At the same time, using NORD PL produces code about as if assembly was used directly, unlike if a more traditional systems language (e.g. C) is used.

== Properties ==
* Conditional compiling
* Declaration statements
* Arithmetical statements
* Constant expressions, evaluated at compile time
* Control statments, including:
:GO unconditional branching
:IF conditional branching
:FOR loop control
:WHILE conditional loop control
:CALL subroutine call
* One pass compiler
* The compiler needs about 6.5Kwords of memory, plus symbol table (5 words per symbol)

I/O must be performed via monitor calls as when writing MAC directly.
