CATEARL18 report

Differences between DSN and VSN used on the PARM of the TLERPT18 ?   

TLERPT18 lists user-specified fields in VSN or DSN order. The user specifies the fields to be reported on by listing the field names in the order they are to appear. You can specify the field names on any number of statements but the total of their lengths cannot exceed 130 characters.

You can use an optional parameter to specify the report order and a title. The default order is by dataset name. If the first 3 characters of the parm are not VSN, the report is one line for each dataset on the VMF in order by DSN then VSN. This is true no matter which field is specified first.

When the first 3 characters of the parm are VSN, the report is in VSN order with one line for each volume. The DSN field value is for the first DSN on each volume.

The field named DSN is 44 characters long. A shortened version of this field can be obtained by specifying a short DSN field name. For example, DSN_15 is a field containing the first 15 characters of the DSN. Fields DSN_3 through DSN_43 are available. The report is sorted by the entire 44 characters of the DSN.
