Opening PAS files

Have a problem opening a .PAS file? We collect information about file formats and can explain what PAS files are. Additionally we recommend software suitable for opening or converting such files.

What is the .PAS file type?

The .pas filename extension is historically associated with Pascal (PAS) source-code files. Pascal is a well-known high-level procedural programming language introduced in 1970 by Niklaus Wirth. Since, Pascal has been quite popular, especially in education. Pascal evolved into Object Pascal, an object-oriented programming (OOP) language, a dialect of which became Delphi, an popular OOP language and environment for developing Windows applications.

A PAS file is a plaintext file containing a source code of a program written in Pascal or Delphi, as Delphi source code files are always conventionally saved as .pas files. PAS files can be opened, viewed and edited with any text editor on any platform. Pascal is a compiler-based language, so PAS files have to be compiled into binaries first to be able to run. For compilation, a .pas file must be processed with a compatible compiler.



In Windows, the .pas extension is often associated with one of the many available Delphi IDE's (Integrated Development Environment).
