I haven't had a chance to verify this yet in the IMAGE/SQL code, however,
I believe the original concept was that an "ITEM < 5" select in IMAGE/SQL
will convert the DBFIND to ITEM = "<5".
 
The primary limitation to TPI/SQL will be keywording/relational access.
Only DBFIND mode 1 lookups will be provided on "Generic" index types.
