MODE IS F, do not use BLOCK CONTAINS
Variable Block File
• Use ORGANISATION IS SEQUENTIAL. Use RECORDING MODE
IS V, BLOCK CONTAINS 0. Do not code the 4 bytes for record
length in FD i.e. JCL REC length will be max REC length
in PGM + 4
Variable Unblocked
• Use ORGANISATION IS SEQUENTIAL. Use RECORDING MODE
IS V, do not use BLOCK CONTAINS. Do not code 4 bytes for
record length in FD i.e. JCL REC length will be max REC

ALTERNATE RECORD KEY IS
RRDS File
• Use ORGANISATION IS RELATIVE, RELATIVE KEY IS
