There is also the poor design of Tape Labels where you have only 17
positions to store the last 17 characters of 18-44 character long
DSNs and also waste 9 of them for GDGs when the G and V values are
already stored in separate fields in the label - IOW: if G and V
are filled in (ie: Not Blank), this data should be used to suffix
the supplied file name with ".GxxxxVyy" so that the limited 17
character field has USEFUL non-redundant information. For legacy
purposes, do a sanity check and allow the use of the GxxxxVyy
suffix in the DSN field for INPUT Tapes that were create before the
new format was established.
There must be a history behind this decision. Can anyone share it?
