Fixed Unblocked
• Use ORGANISATION IS SEQUENTIAL. Use RECORDING
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
length in PGM + 4.

ESDS VSAM file

KSDS VSAM file
• Use ORGANISATION IS INDEXED, RECORD KEY IS,
ALTERNATE RECORD KEY IS

RRDS File
• Use ORGANISATION IS RELATIVE, RELATIVE KEY IS

Printer File
• Use ORGANISATION IS SEQUENTIAL. Use RECORDING MODE

and access mode.
then in data division add file descriptor entry for each
file.These must be in file section.
Then use these files in procedure division.
