CVAFSEQ Macro Overview and Specification

The CVAFSEQ macro can be used to:

Read an indexed VTOC sequentially in data-set-name (DSN) order
Read an indexed VTOC or a nonindexed VTOC in physical-sequential order.

See Accessing DSNs or DSCBs in Sequential Order for additional information.

The format of the CVAFSEQ macro is:
