The solution to most debugging problems, in all languages,
including Prolog, follows from taking this statement
>I have used the following, and it is not doing the right thing.
and filling in the blanks in this statement:

I have used the following and it acts precisely as if it was ___.

It helps to be able to say precisely when the bug happens,
how it happens, and where it happens.  It also helps to know
when, where, how it does *not* happen.

This is from a very good little book on Program Debugging
in the British Isles by Brown & Sampson (McGrawHill/Elsevier).
