? How to access C-ISAM File with SQL

One of my customer uses C-ISAM files. I would like to know if it's possible to access the contain of these files with SQL language ? I think that it can be possible if I install an Informix SE kernel on his Unix machine ? Is there a technote that explain how to doing this ? Thanks in advance. --->> On our site a SHAREWARE SQL Query Tool <<------- --->> & a middleware much faster than SQL*Net <<------- Frederic BOUQUET Client/Server & SQL RDBMS email: fbouquet@cornut.fr http://www.cornut.fr/
