@ Daz + MarzMan: to quote a paragraph from the book:
"This book was most certainly not written for experienced programmers. If you have a knack for new software and you are able to install DarkBASIC and within minutes write a somple program without breaking a sweat, then you are too advanced for this book. However, if you have experience writing code but would like to know more abour DarkBASIC Professional (the latest version from Dark Basic software ltd, which was released in late 2002), then i think you will find this book useful because it covers both versions. (In fact, the book is possibly a little slanted toward DarkBASIC Professional.)"
Hope this is of use.
