TLBL Statements TLBL Options
Chapter 5. BIM-EPIC TLBL and DLBL Statements 5-7
Rewinds and unloads the tape at close.
Prevents rewinding the tape at close. Use this option when you are creating multi-dataset
tapes.
Scratches the dataset when it is closed as input. This option does not affect subdatasets.
Prevents BIM-EPIC from releasing the tape drive at close. If Autoattach is on, it also prevents
the drive from being detached. The drive will be released at end-of-job, when the logical unit
is assigned to another device, or when the tape drive is deviced down, whichever occurs first.
Use this option when your program issues multiple "open" requests for the same DTF name.
While VSE alone would process the original label each time the same DTF name is opened
with the drop option, BIM-EPIC processes the next label in the JCL with that DTF name.
(Dataset drop differs from concatenation, since concatenation processes multiple datasets with
one open.)
Puts the version in the DSN Catalog with conditional catalog status.
Reads multiple files using only one open. The files are read as a single dataset. This process
is called dataset concatenation. Use concatenation to read multiple files when your program
performs only one open. This option is valid for controlled datasets only. For coding,
examples, and limitations, see 6-4 in this manual.
Inhibits LUB allocation for the dataset. Inhibiting LUB allocation is often necessary when
you are running programs that use physical IOCS, or the BIM-EPIC TSIDASS program. You
do not have to specify this option when LUB allocation is turned off automatically or when a
SYS number is specified in the dataset definition.
