*About this book* **Pascal from BASIC** is designed for users who are new to Pascal but who are already able to program in BASIC. For them, the task is to realign their thinking on the subject of programming, not to learn it from scratch. The book builds on the reader's knowledge of BASIC and uses it to introduce the ideas behind Pascal. These new concepts are illustrated by examples and the advantages and disadvantages are discussed. This book first appeared under the title **Pascal from BASIC** under an Addison-Wesley imprint.
