Errors in "Inside CorelCAD - 2015 Edition"?

So I have CorelCAD 2016 but no eBook available for it so i bought the 2015 version eBook. I assume most things function the same way.

Page 50 and 55 of this book tell me to specify cylindrical coordinates as follows:

"x,y<a     indicates cylindrical coordinates"

That won't work. I checked in the Help files and it correctly told me to specify cylindrical coordinates as:

x<a,z (distance,<angle,z-coordinate)

This does work.

So is the eBook simply wrong or did this change between 2015 and 2016 versions? If so will this eBook prove to be inaccurate for users of 2016?

If it is just a mistake in the book, who can I report the error to?

 

Thanks, John
