Thread: ISAM to SQL
I see a few old messages referring to ISAM to SQL emulation.
Does anyone know of any actual source code to one of these projects? Any active projects?

Any > active projects? I wrote an unfortunately closed source ISAM driver for postgresql for COBOL (AcuCobol). It was not a too terribly difficult project -- Postgres has a couple of features that made it pretty easy, especially advisory locks and row-wise comparison. Type conversion can be difficult or complex depending on how far you want to take things and how clean the API is that you will be hooking on the ISAM side. I almost put together a C-ISAM driver a couple years back for a project but it fell through. merlin
