For the ISAM context this whole discussion is kinda moot, because you
really don't want to have to plan and execute a fairly expensive query
for every record fetch.  If we had all the improvements discussed, it
would be a reasonably cheap operation by the standards of "execute
an independent query", but by the standards of "fetch next record
in my query" it'll still suck.  (Using PREPARE might help, but only

It strikes me that what you really want for ISAM is to improve the
cursor mechanism so it will do the things you need.  I'm not sure
what's involved, but let's talk about that angle for a bit.
