<on accessing params by index>

You don't have to. Once the statement is prepared the references to
the TIB_Column or TParam objects are stable. Access them by name
outside the execution loop and store each in a local variable, then
access the local variables inside the execution loop.

I never access anything by index for clearness and ease of
maintenance.
