You are responsible for defining a dataset that will store variable-length records with a maximum length of 100 bytes. Which RECFM and LRECL values would you choose, and why?
- RECFM=FB, LRECL=100
- RECFM=FB, LRECL=80
- RECFM=VB, LRECL=100
- RECFM=VB, LRECL=80
Variable-Length records are best suited for RECFM=VB, and LRECL should be set to the maximum expected length of a record to efficiently store varying lengths within the dataset.
