How do you reference the following file formats from COBOL programs:
Fixed Block File - Use ORGANISATION IS SEQUENTIAL, use RECORDING MODE IS F,BLOCK CONTAINS 0
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 ie 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 ie JCL rec length will be max rec length in pgm + 4.
ESDS VSAM file - Use ORGANISATION IS SEQUENTIAL.
KSDS VSAM file - Use ORGANISATION IS INDEXED, RECORD KEY IS, ALTERNATE RECORD KEY IS RRDS File - Use ORGANISATION RELATIVE,
RELATIVE KEY IS Printer File - Use ORGANISATION IS SEQUENTIAL. Use ORGANISATION MODE IS F, BLOCK CONTAINS 0. (Use RECFM=FBA in JCL DCB).
