# Bug in SubrtnSig logic.  If a SELECT statement is copied and the copy
# is subsequently modified, we need to change the Select.selId on the
# copy so that when the copy is used to generate code, the SubrtnSig
# logic won't try to substitute the original SELECT in place of the
# copy which is now different.
