Does anyone know of a version of COBOL or a decent(ish) DMBS suite or set
of routines so I don't have to go to the trouble of coding my own ?

I'm trying to port a load of COBOL s/w from and RS/6000 - just to see if
it can be done.

The alternative is to start from scratch (Billing systems so I don't
really want to do that!)
