Example

In the following example, the non-VSAM data set named A.B.C is cataloged. The data set is stored on two volumes.

          CATALOG ADDABC             CATALOG DATA SET A.B.C.

          DC         H'0'            SEQUENCE NUMBER

The CATALOG macro instruction points to the CAMLST macro instruction. CAT, the first operand of CAMLST, specifies that a data set is to be cataloged. DSNAME, the second operand, specifies the virtual storage location of the data set name A.B.C. VOLUMES, the fourth operand, specifies the virtual storage location of the volume list.

Control is returned to your program at the instruction following the CATALOG macro instruction. Register 15 contains one of the return codes described under Return Codes from CATALOG.
