Use I4GL 4.0 with Dynamic Workgroup Server?

Hi, We've got a number of old i4gl programs written using version 4.0 of i4gl, and accessing a version 4 standard engine database under SCO UNIX. We're planning on installing the new Informix Dynamic server (workgroup) edition, running under either SCO or NT (not decided yet). Ideally, we'd like to transfer the database from the standard engine, to the new workgroup server. Does anyone know if it is possible to make the old 4GL programs use the dynamic server database, instead of the old standard engine one (ideally without buying a new version of I4GL, as we no long do any new development on this). Would Informix Net help with this? (I believe we may have an old version 4 copy of this lying around). Thanks for any help or suggestions. -- Wookie
