Pascal Intro Pdf Programming Language Computer Program Reserved words: there are certain reserved words that have a predefined meaning in pascal. these reserved words can be used only for their intended(predefined) purpose. Introduction the pascal programming language was created by niklaus wirth in 1970. it was named after blaise pascal, a famous french mathematician. it was made as a language to teach programming. The statements in pascal are designed with some specific pascal words, which are called the reserved words. for example, the words, program, input, output, var, real, begin, readline, writeline and end are all reserved words. First the expression is evaluated, then the computed value is stored in the portion of computer memory reserved for the variable. of course the value of the expression must be compatible with the type of variable on the left.

We make a distinction between turbo pascal and delphi reserved words. in tp mode, only the turbo pascal reserved words are recognized, but the delphi ones can be redefined. Functions and procedures pascal has explicit differentiation between functions and procedures different reserved words functions must return a value procedures do not return a value recursion allowed. A variable within a pascal program is assigned a type, which determines what can be stored in it, i.e. if a variable name identifies a particular box in memory the type gives the kind of item that the box can hold. This document provides an introduction and overview of the pascal programming language. it discusses that pascal is a general purpose language that is widely available and good for learning programming principles.
