Opis

This book is the first volume in a series entitled The Modula-2 Software Component Library. Charles Lins collection of reusable standard software components, could be the basis for every programmers software project in Modula-2. Components that are implementations of commonly used data structures are presented, along with an adequate description of their functionality and efficiency. Moreover, the books provide the background necessary to tailor these components to the specific needs of any Modula-2 environment. For every Modula-2 programmer this series of books might prove as useful and indispensible as the original language reference by Niklaus Wirth.
