, A preliminary version o the programming language Pascal was dra ted in 1968. It ollowed in its spirit the A1gol-6m and Algo1-W 1ine o 1anguages. A ter an extensive deve10pment phase, a irst compiler became operational in 197m, and pub1ication ollowed a year 1ater (see Re erences 1 and 8, p.1m4). The growing interest in the deve10pment of compilers or other computers ca11ed or a conso1idation o Pascal, and two years of experience in the use o the 1anguage dictated a few revisions. This 1ed in 1973 to the pub1ication o a Revised Report and a de inition o a 1anguage representation in terms of the ISO cha: .: .acter set. This booklet consists o two parts: The User Manual, and the Revised Report. The ManUAl is directed to those who have previous1y acquired some ami1iarity with computer programming, and who wish to get acquainted with the 1anguage Pascal. Hence, the style o the Manual is that o a tutorial, and many examp1e are inc1uded to demonstrate the various eatures o Pascal. Summarising tab1es and syntax speci ications are added as Appendices. The Report is inc1uded in this booklet to serve as a concise, u1timate reference or both programmers and imp1ementors. It defines stAndArd Pascal which constitutes a common base between various implementations of the 1anguage.
