This book was written in 1987 and assumes that you are already familiar with Turbo Pascal. There is a review of Pascal, but if you are a beginner, this will not help you. You need to have a working knowledge to use this best.This also was originally published as "Advanced Turbo Pascal: Programming and Techniques." The main difference is the addition of Turbo Pascal Database Toolbox and Turbo Pascal Graphix Toolbox.This text covers dynamic allocation, interfacing to assembly language routines, encryption and data compression, and expression parsing and evaluation. It also has a section in the appendix on converting C and BASIC programs to Turbo Pascal. Each program is explained well for the reader.If you are still working with Turbo Pascal, this has some good examples for you.
