Tables and file processing, including sorting and master file updating are covered in chapters 12 through 19. Chapter 21 provides some nice date algorithms, along with some of the intrinsic date functions. Chapter 22 is devoted entirely to intrinsic functions. This time for devoting an entire chapter to intrinsics, thereby placing the emphasis where it belongs. My only negative comment is that I would like to see the intrinsics introduced much earlier in the book.
Intrinsic functions are easy to understand, apply, and provide tremendous productivity gains.
A nice chapter, brief but thorough. One feature not covered is the ability of subprograms to control state using the keywords Cancel and Initial. Flexus markets a powerful and versatile tool and I'm glad to see Hubbell introduce and explain the product in his book. Often books will devote the same number of pages to the intricacies of some arcane feature as they do on the significant constructs, improperly implying one is as important as the other. Hubbell does not fall into this trap and rightly emphasizes the features that are most useful and meaningful.
