Think twice
Very helpful, but badly editedYou will of course need to tune them, but I am generally very impressed.
The prose is also very good, and I have much better insight about how to design systems like this.
The only downside is that the code fragments in the book
1) are not available for download on the web, which is just silly in this day and age;
2) are very poorly edited; they contain syntax errors and obvious bugs.
So poor technical editing, but great content.
Introduction to Programing strategies in EasyLanguageOther EasyLanguage guides are somewhat dated (though, I still find them interesting). Check out "Ask Mr. EasyLanguage" and "Using Easy Language" if you want to comparison shop.
Much of the book can be found elsewhere, particularly the online TradeStation manuals. 90 pages of appendix comes straight from the online 'EasyLanguage Reference Guide' (a pdf file). What is unique about the book is the 'system development' perspective. The online guides offer little or no help developing trading systems.
The CD contains the code described in the book. The code could have been put on 2 floppy disks, but I guess a CD is cheaper and saves space.

"200 pages?" you say. Yes, about half of the book is dedicated to the title subject. Another 200 pages of "stuff" was inexplicably tacked on. A stock option course, interviews with traders, and appendices from EasyLanguage online reference. The book is so poorly edited that it refers to Appendix A as a function list, but the appendix is actually a much less useful list of syntax errors. Typos throughout.
