Thanks to those who have replied, but I am still stuck
and confused.

Doug has an example including both Component Pascal & C.
I don't pretend to understand the C. The CP is also a mystery,
he has empty procedures without the EMPTY (or ABSTRACT) keywords.
I think it is an example of BlackBox reading a dll written elsewhere,
which is the opposite of what I want to do. But the C also looks empty!

Fyodor has sent me 9 pages of C. Thanks for your effort, but I am no wiser.

We have written an integer add dll in Delphi. The code is short and simple
(certainly not 9 pages of sandscript or whatever). We can use it in BlackBox
or Visual basic; in each case the code is no more that 3 or 4 lines. The dll
is 85 kbytes. The Windows NT utility Quick View shows the entry point in an
'Export Table'

I have written a BlackBox module to use the BlackBox example dll Mydll. This
takes about 2 lines and works.

BUT I CAN'T use it from Visual Basic, which says 'Can't find entry point Gcd'.
This is consistent with the Quick View utility, which does not have an Export
table for it.

What am I missing?. Is there a way/need to add entry points to Mydll?

Robert
