Pascal is a popular imperative and procedural programming language that Niklaus Wirth created in 1969 and released in 1970 as a compact and fast language. It was designed primarily (but not only) to teach students structured programming and data organizing.
Pascal is an algol descendent, although it was implemented on various architectures, including PDP-11s, IBM PCs, and CDC Cyber and IBM System 370 mainframes. Pascal's critical mass was most likely attained when Borland launched Turbo Pascal in 1983.
Wirth also created Modula-2 and Oberon, which share Pascal's design. OOP-based Object Pascal (used in Delphi and Lazarus/Free Pascal) is another derivation.
Pascal is an entirely procedural language containing control statements that include reserved terms like if, then, otherwise, while, for, etc. On the other hand, Pascal contains various data structuring features and other abstractions not found in ALGOL 60, such as type definitions, records, pointers, enumerations, and sets.
