Dear Mr. Gaunt (et al.):
What QDB* APIs? The only QDB* APIs I've
ever heard of are concerned with
retrieving meta-data about a file's
format(s), not with actual I/O. In this
case, the actual I/O goes through
calls to what appears to be the RPG runtime
(particularly likely,
considering as how the program in question has an RPG
compiler's
fingerprints all over this section of source code, and used to have
them all
over most of its 20k+ lines of code).

Since the I/O uses system calls for
which I have no docs, I've left most of the
routines dealing with it alone,
except for occasionally making certain
"invisible" variables "visible" for
debugging purposes, and changing some
generated names to more meaningful
ones.
