Pascal is an influential imperative and procedural programming language, largely (but not exclusively) intended to teach students structured programming and data structuring. Pasca was implemented on a wide range of architectures, from early PCs to mainframes. Pascal derivatives include OOP-based Object Pascal (used in Delphi and Lazarus/Free Pascal). Pascal is a purely procedural language and includes control statements with reserved words, but has many data structuring facilities and other abstractions like type definitions, records, pointers, enumerations, and sets.
