The $TINFO utility is designed to work with the ISPF DSLIST (a.k.a "=3.4")
screen in that you can place $tinfo next to a dataset name on the 3.4 screen,
press , and it will process. $TINFO's function is to query the TMS
(Tape Management Software) system and return information such as create date,
create job, offsite status, etc. for a tape dataset.
For instance, if you are going to submit a job to process against one of the
"DAILY" tapes, you can use $TINFO to determine if the tape is onsite or offsite
before you submit a job. You might also want to know the create date of one of
these tapes to make sure you process against the correct one.
