Hi Priya,

All VSAM requests are for unblocked records. If the processing program
requests blocked records, the ISAM interface program sets the overflow-record indicator for each record to indicate that each is being passed to the program unblocked.

F Indicates fixed-length records.
FB Indicates blocked fixed-length records.
V Indicates variable-length records. If no RECFM is specified in
the AMP parameter or in the DCB, V is the default.
VB Indicates blocked variable-length records.
