IBM Informix 4GL reference version

Several versions of the IBM® Informix® 4GL language have been released. It started in the mid-80s with I4GL version 4.x; then came version 6.x in 1996. I4GL version 7.2 was released in 1998; then versions 7.31, 7.32, and finally the version: 7.50 came out.

There have been several bug fixes and enhancements over the life of I4GL, resulting in releases that slightly differ. Supporting strict compatibility with all versions of I4GL is not possible for Genero BDL.

The Genero BDL compatibility level with IBM Informix 4GL is achieved by comparing with the latest version of I4GL, which is version 7.50 at the time of this writing.
