Cezzar's text was excellent in understanding the tapestry of languages that I have heard of or been involved with over past 15 years. This text superbly and clearly defined strengths and weaknesses, similarities and differences, and appropriate applications. Each language (or language group) is then discussed in detail with full or partial programs comparing and contrasting them.
Its only failing is that it was written in the early 1990's. Since publication, a new family of languages has been developed that are designed to be platform independent. A new edition is needed to show how Java and similar languages relate, fit into, and extend the mosaic presented.
I highly recommend this book for decision-makers in the software industry, programmers who need to expand their understanding of the field, and newcomers wishing to make a stake in software.
