A PTF flagged as PE will have error holds on it. Each error hold has an
associated APAR,and each PTF will supersede each APAR that it corrects. The
correcting PTF might have sufficient comments, or you might have to read the
description of each APAR.
Does _console2() delete the CIB in order to allow and additional MODIFY?
