[Zope] Constructing a DCOracle2 BindingArray to match an OUT parameter

Hopefully this is not OT for this list. I am having trouble understanding how to construct a BindingArray object to match and OUT param being used in one of my stored procedures. The OUT is defined in the PACKAGE as: TYPE result_rec is RECORD ( sample_id wells.sample_id_dn%TYPE, ... etc ... ); TYPE result_table IS TABLE OF result_rec index by BINARY_INTEGER; PROCEDURE get_qc_report ( result_tab_io IN OUT result_table, ... etc ... ) If I try to pass in (just guessing), for example: results = cnx.BindingArray(1, 9, 'SQLT_REF') All I get is an "ORA-00000" results = cnx.BindingArray(1, 9, 'SQLT_RSET') segfaults and brings down my Zope ... I'm not sure what kind of BindingArray I should be using.
