So I have a DataEase DOS 4.23 database, which I have full access to open and look at, and I'm looking to see if I can somehow convert this into a MSSQL or PGSQL (or any modern SQL, really) database. I've looked through this software, and I can't seem to find any sort of export function. I've found some documents that say to upgrade the system to 5.x, which has an export function, but I've had trouble locating an installer for DataEase 5.x.
Is there any known way to programmatically export the DQL to a more modern format? Even CSV is acceptable to me at this point.
