Hiya - I'm checking the launch flags, it's a sub call all right, the
CodeWarior debugger shows my globals as being NULL pointers, so I can't use
them to obtain the DmOpenRef already in use.
Hence I call my open database routine, and it fails with
dmErrAlreadyOpenForWrites as mentioned above.
Sorry for all the questions :(
