Larry Wall created practical Extension and Report Language, otherwise known as PERL. It is a programming language with very few limitations relative to several other scripting languages and excellent quality of text processing. It is largely taken from the C scripting and programming language but also adapts from a few others like AWK and SH or shell scripting. The file extension PL is the main format that results from using this programming language.The PL file extension is also referred to sometimes as the PERL file type. Its features are tool definition, indentation mechanism, and highlighting. These make the file type convenient to use. However, the PERL script interpreter must first be run to be able to make usable the .pl file extension. More often than not, the PERL script interpreter is installed using the Internet and Web Servers.The highlighting feature refers to differentiating characters, strings, logical, variables, and comments of PERL through rendering them in various colours. On the other hand, the indentation mechanism refers to the text automatically aligning or indenting. It is a mechanism, which formats the text easily. Lastly, tool definition is the PL file extension being edited conveniently through altering just a keyword or two.The file extension PL is usually utilized for multiple programming, GUI development, and web programming. In some cases, it substitutes .html files because the files with the .pl file extension are more advanced and more convenient to use. They are also sometimes used in system administration management and overviewing by Web Servers, and some other uses that require text to be manipulated conveniently.Unlike other types of file extensions, which have small texts, minimal characters, and tries to be beautiful and elegant more than usable, the file extension PL is usually referred to as practical. It is because it is very procedural, object-oriented, and extremely complete. It can support data structures, which are complex, complier directives, and object-oriented programming models.

What is this pl file?

2D or 3D image plot created with BRL-CAD, a combinatorial Constructive Solid Geometry (CSG) solid modeling system; typically generated with MGED (Multi-Device Geometry Editor), included in the BRL-CAD software package. NOTE: PL files can be converted to standard .PNG image files using BRL-CAD's pl-fb and fb-png commands.

Prolog is a logic programming language. It is a general purpose language often associated with artificial intelligence and computational linguistics. It has a purely logical subset, called "pure Prolog", as well as a number of extralogical features. Having its roots in formal logic, and unlike many other programming languages, Prolog is declarative: The program logic is expressed in terms of relations, and execution is triggered by running queries over these relations. Relations and queries are constructed using Prolog's single data type, the term. Relations are defined by clauses. Given a query, the Prolog engine attempts to find a resolution refutation of the negated query. If the negated query can be refuted, i.e., an instantiation for all free variables is found that makes the union of clauses and the singleton set consisting of the negated query false, it follows that the original query, with the found instantiation applied, is a logical consequence of the program. This makes Prolog (and other logic programming languages) particularly useful for database, symbolic mathematics, and language parsing applications. Because Prolog allows impure predicates, checking the truth value of certain special predicates may have some deliberate side effect, such as printing a value to the screen. This permits the programmer to use some amount of conventional imperative programming when the logical paradigm is inconvenient. The language was first conceived by a group around Alain Colmerauer in Marseille, France, in the early 1970s, while the first compiler was written by David H. D. Warren in Edinburgh, Scotland. Prolog was one of the first logic programming languages, and remains among the most popular such languages today, with many free and commercial implementations available. While initially aimed at natural language processing, the language has since then stretched far into other areas like theorem proving, expert systems, games, automated answering systems, ontologies and sophisticated control systems, and modern Prolog environments support the creation of graphical user interfaces, as well as administrative and networked applications.
