Quinn Wildman noted in the newsgroups that the IB docs have been updated:
Although few if anyone (other than me!) have noticed, the documentation included with Borland InterBase home page, InterBase 7.5.1 had a number of "issues", namely a number of features added in 7.5.0 were not there! These issues have been a resolved and the new documentation is available for download in the registered users area. This documentation should be nearly the same as the documentation included with 7.5.0, so if you have that documentation you don't need to download this new set.
Look at detailed information.
