I had an Interbase 5 db that a long time ago transfered to Firebird 1
and later to 1.5
I have no problem with that db, everything works as expected but a
minor Shema problem.

Whenever I extract metadata I see thes tables in the produced SQL.

CREATE TABLE IBE$AUTO_FIELDS
CREATE TABLE IBE$CATEGS
CREATE TABLE IBE$CHAMPS
CREATE TABLE IBE$DOC
CREATE TABLE IBE$DOC_ATTRIBUTS
CREATE TABLE IBE$DOC_RELATIONS
CREATE TABLE IBE$WORK_TABLES

I can understand that these tables are of system type but I don't know
if are Firebird needs them or are some tables trashed from ver 5, as
they contain no data.

What can I do to not see them?

Thanks a lot.
