A status of PERMANENT means to keep the entry until it is erased with a DELETE 
TAPEFILE command. A permanent entry can be subsequently given a retention 
period with an ALTER TAPEFILE command.
ZRESETTIME
corresponds to the RESET EXPIRATION parameter of the MEDIACOM ALTER 
MEDIADEFS command. ZRESETTIME verifies that the system clock is correct 
when an error condition is detected by the cleanup process (which is either run 
automatically or run manually through the execution of the EXPIRE TAPEFILE 
command).
ZAUTOMATED
corresponds to the AUTOMATED parameter of the MEDIACOM ALTER 
MEDIADEFS command. ZAUTOMATED denotes how many times an attempt is 
made to automatically select and mount a scratch tape on an ACS tape drive. The 
value for this field is used when the AUTOMATED attribute is not used in a 
TAPECATALOG DEFINE. Valid values are: 
ZCOMPRESSION
corresponds to the COMPRESSION parameter of the MEDIACOM ALTER 
MEDIADEFS command. ZCOMPRESSION denotes whether compression is used 
when writing data to a tape. The value for this field is used when the 
COMPRESSION attribute is not used in a TAPECATALOG DEFINE. Valid values 
are:  
ZMCS-VAL-AUTOMATED-UNSPECIF
The value is unspecified.
ZMCS-VAL-AUTOMATED-OFF
$ZSVR requests DSM/TC one time (default).
ZMCS-VAL-AUTOMATED-ON
$ZSVR requests DSM/TC a total of 10 times.
ZMCS-VAL-COMPRESSION-UNSPECIF
The value is unspecified.
ZMCS-VAL-COMPRESSION-OFF
The value does not use compression when 
writing the data (default).
ZMCS-VAL-COMPRESSION-IDRC
The value uses compression when writing 
the data.
