Multi command string queries don't support parameterization. The way
I do it is to keep an application managed stack of data (as an array
of record types) to send that is accumulated when the last stack is in
transit. Then when the last response comes in you repeat.
Of course, if you could parameterize a multi command string statement,
that might be a better way to go.
