and another one:
  If you're only interested in the "puts" from that procedure,
but *not* in any puts' inside the nested procedures (e.g. the bid...)
then you can regsub the procedure's body, and change all the puts
to (e.g.) "logputs" and provide an appropriate procedure "logputs"
on your own for your needs.
