Can you please add GnuCOBOL 4+ indexed handler ODBC?
Adding this to the general tests and documentation here would be good - so additional to the esql demo you'd have an indexed-sql demo, ideally accessing the same tables as in the esql one.
And from that (or possibly first): an indexed-sql demo that uses "plain common INDEXED" access starting with
OPEN OUTPUT (and possibly a second
OPTIONAL file) and a second esql demo that then accesses these "files" via
