Tip: How to find the meaning of BDE error-codes in Delphi

In the DOCS directory you will find a file, BDE.INT or DBIERRS.INT,
which contains Pascal declarations for the layout of BDE error codes.

The BDE error-code is in two bytes, where the left byte is an error
category (expressed in hexadecimal in the source-file), while the right
byte is an error-code within that category.
