It was widely used as a teaching language in university-level programming courses in the 1980s, and also used in production settings for writing commercial software during the same period. Compilers were also available for many microcomputers as the field emerged in the late 1970s. Pascal became very successful in the 1970s, notably on the burgeoning minicomputer market. This is similar to the block structure of ALGOL 60, but restricted from arbitrary block statements to just procedures and functions. A program is thus syntactically similar to a single procedure or function. Unlike C (and most languages in the C-family), Pascal allows nested procedure definitions to any level of depth, and also allows most kinds of definitions and declarations inside subroutines (procedures and functions). Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversions. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. This was not accepted, and the ALGOL X process bogged down. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. Pascal was developed on the pattern of the ALGOL 60 language. It is named after French mathematician, philosopher and physicist Blaise Pascal. It comes in both 32-bit and 64-bit downloads.Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring.
