Control-M/Tape treats the following JCL retention parameters in the standard way:

RETPD=0

For temporary data sets that are scratched after use.

RETPD=dddd

Standard retention period (dddd is number of days).

EXPDT=yyddd

Standard expiration date (yyddd is the Julian date).

EXPDT=yyyy/ddd

Standard expiration date (yyy/ddd is the Julian date).

EXPDT=99365

Permanent retention.

EXPDT=99366

Permanent retention.

In addition, Control-M/Tape treats the following EXPDT value in a special way:

EXPDT=98000

Volume is not managed by Control-M/Tape. Control-M/Tape processing is bypassed.

EXPDT=99000

Retention is controlled by the operating system catalog. The data set is scratched when there is no longer an entry in the catalog.

If member CTTPARM in the IOA PARM library includes EXPDTYPE=CA1 to request compatibility with the CA-1 tape management system, Control-M/Tape treats the following EXPDT values in a special way:

EXPDT=99ccc

Cycle control. ccc is the number of cycles retained, independently of the operating system catalog. An installation parametera defines a cycle (for example, each new generation (version) of the data set).

EXPDT=98ddd

The data set is scratched if it is not used during a period of ddd days. ddd is the number of days since last access.

EXPDT=90ccc

Catalog and DAYs control. ddd is the number of days since creation.

The dataset expires only after it is removed from the catalog and ccc days passed since its creation

If the CTTPARM member includes the expression EXPDTYPE=TLMS to request compatibility with the CA-TLMS tape management system, Control-M/Tape treats the following EXPDT values in a special way:

EXPDT=990cc

Cycle control. cc is the number of cycles retained, independently of the operating system catalog. An installation parameter defines a cycle. For example, each new generation (version) of the data set.

EXPDT=991dd

Catalog and date control. dd is the number of days since creation.

EXPDT=992dd

Days since creation. dd is the number of days.

EXPDT=98ddd

The data set is scratched if it is not used during a period of ddd days. ddd is the number of days since last access.
