OK - some more clues: If you open the code files (*.ocf) generated in
BlackBox you will see that the 16 bytes that you saved in the 'code size'
(from 524 to 508) when you uncommented s:Stores.Operation has led to a
compensating 16 bytes increase in the 'meta size' (from 304 to 320). So it
looks like the information has just moved to a different section of the code
file.

Of additional interest is that if you remove the Stores declaration from the
IMPORT list as well as the VAR declaration there is no change. However, that
is likely because Stores is indirectly IMPORTed by one or more of the other
modules anyway.

I have a hunch why all this is so but don't know enough about it to be able
to explain it confidently to anybody else. If you can find out what is
stored in the 'meta' section (RTTI - runtime type information?), when and
why - I think you'll have the answer.

Chris
