Using variable-length RRDS
To use relative-record data sets (RRDS) that have variable-length records, you must use VSAM variable-length RRDS support.
Do these steps:
- Define the file with the
ORGANIZATION IS RELATIVE
clause. - Use
FD
entries to describe the records with variable-length sizes. - Define the VSAM file through access-method services as an RRDS.
