A PN file is a source code file written in the Pinecone programming language, which is a general-purpose, multi-paradigm language. It stores source code, which includes variables, functions, and user-defined structures, that can be compiled to the C++ programming language.

PN file open in Microsoft Visual Studio Code 1 You will most likely only encounter a PN file if you are a program developer working with the Pinecone programming language, which is rather obscure. If you need to open a PN file to view or edit its contents, you can use a text editor since the language is stored as plain text. The Pinecone programming language was developed in 2016 by William Wold. The programming language features a simple, consistent syntax and requires a C++11 compiler to be built. Some other implemented features include: Constants Data structs Flow control (if, if/else, while loop, for loop) Functions Int arrays Interpreter Operators, including +, *, %, :, =, >, <=, and &&. Primitive data types Bool, Int, and Dub Running system commands Single and multi-line comments Strings and various String operations Transpiler to C++ for max performance Tuples User input NOTE: Pinecone is no longer developed or maintained.
