Query: Authors know QBASIC, but don't know English

This book is entirely unsuitable for beginning programmers, and difficult to read even for experienced programmers. All the information is there, even on advanced topics, but the authors write in mock-Soviet Academese. There is also no reference appendix or any way to quickly look up commands (though QBASIC itself provides that). Here are a couple of sentences from the first paragraph in the book: "Statements must be written according to QBasic syntax rules. Why, for example, is the comment text in the INPUT statement enclosed in quotation marks, and the variable name placed after the comma?" This is gobbly-gook to anyone who doesn't already know alot about programming in general and BASIC in particular. It gets worse from there. Do not buy this book unless you are an experienced BASIC programmer looking for advanced info on QBASIC for DOS audio and graphics programming, and don't want or need any kind of useable quick-reference to the language.
