Since the SORTIN tape volumes will be read in any order and on a SORTPARn tape unit location determined by the PARASORT logic, it is possible to receive messages on the console log that indicate out of sequence processing of the volumes of the SORTIN data set. Messages such as the following may be generated:
IEC712I ... SORTPARn READ - NOT FIRST VOLUME OF DATA SET
or
IEC710I ... SORTPARn ANOTHER VOLUME EXPECTED
These messages can be disregarded since this type of processing is deliberate with PARASORT.
