How are they different? Except that interbase doesn't understand the
word NIL but does NULL?

They can mean the same thing, depending on what language you use them
in.

SQL: NULL=absence of value
Delphi: nil=pointer to zero
Javascript: null=no object
C: null=just about anything you like

(I'm probably wrong about some of that, but you get the general
idea...)
