In a TLBL Statement
Here is an example of length specification on the TLBL statement:
// TLBL EFILE,'ERROR FILE,XS'
In DYNCAT Commands
Establish the length of the tape when initializing the volume with the DYNCAT
INT or INTR commands. This information is maintained in the Catalog, not on
the physical VOL1/HDR1 of the tape. Specifying length is unnecessary if your
tape library has only one size of tape reel. Several examples follow:
Examples:
The tape on drive 280 is initialized with volume serial number 1001 as an
extra short tape.
INT 280 VOLSER=(1001) LENGTH=XS
The tape on the drive to which SYS008 is assigned is initialized with volume
serial number 1002 as a short tape, owned by PR.
INT SYS008 VOLSER=(1002) LENGTH=S OWNER=PR
The tape on drive 281 is read to determine the volume serial number so that
the operator can verify that it is correct. Next the tape is initialized with its
previous number (unless the operator overrides it) as a medium short tape.
INT 281 LENGTH=MS
