Import List Volume
Just as with the Export List volume, the Import List volume format is described in
hierarchical form in the tables below. Start with Table 36, then proceed as directed
to the portion(s) of interest. All character fields within the volume are in EBCDIC.
Field contents specified in quotes are EBCDIC characters. The volume must be
written with compaction turned off.

The format of the Import List File record is designed to allow for ease of use. It is
expected that a customer may manually input the needed information and the
format needs to be tolerant of the location of the fields in the record. Each list file
record contains up to three fields separated by delimiters. The fields “physical
volser”, “logical volser”, and “Import Option” must appear in that order, separated by
a field delimiter. If the record is not equal to 80 bytes, the record is not processed
