Modula-2
Peter C. Capon, Pete J. Jinks · 1988
This book has dealt almost exclusively with Pascal. Since the definition of Pascal many new computer languages have been invented. Some of these have provided additional features while retaining the general framework of a Pascal-like approach. Two such languages are Modula-2 and Pascal Plus. They both have many similarities to Pascal but provide new facilities in areas where Pascal is considered deficient. The two main areas addressed by these languages are the modularisation of programs into manageable independent parts and the expression of concurrency, or several simultaneous activities. The principles, and much of the detail, of the Pascal compiler presented so far apply equally well to these languages. The extensions needed to implement the additional features for Modula-2 are quite limited and are described below.
