For VSAM Files

For VSAM dataviews, the Dataview Message Line shows the type of VSAM file, the maximum record size, and the name of the file. The format of the Dataview Message Line for VSAM files is:

For Fixed‑length Files

CATALOGED mm/dd/yy hh:mm   VSAM  type UPD=xxx FILENAME xxxxxxx
                           FIXED LENGTH RECORD      RECSIZE  xxxx

For Variable‑occurrence Files

CATALOGED mm/dd/yy hh:mm     VSAM  type UPD=xxx FILENAME xxxxxxx
                             VAR OCCURRENCE RECORD    MAX RECSIZE  xxxx

For Variable‑segment Files

CATALOGED mm/dd/yy hh:mm     VSAM  type UPD=xxx FILENAME xxxxxxx
                             VAR SEGMENT RECORD   MAX RECSIZE  xxxx

Note: For RRDS files defined with variable‑segment records, the second line of the dataview display shows only the record size since RRDS records are always written as fixed‑length records.
