Hi Frank,
Btw, I think we can have such feature as
convert ObjectPtr link <=> binaryLink.
We already have
RDB link => ObjectPtr link
In short this task can be and should be resolved.

But you cannot SELECT binary link!
What this means?
SELECT link_name FROM ???
^^^^^^^^^^^^^^^^^^^^^^^^^
No way.
It is possible of course invent a little own SQL,
E.g. We have in SQL92 syntax
Table T = SELECT * FROM T
So I think we can easy do:
Link L
And this will show 2 (n) columns that should pairs of RecId of linked
records. Hmm, good idea!
And this can be returns as cursor somehow...
Frank, please add this to Mantis!

I have not understand your idea.
Please explain more.
