In the old days, the FB 340 340 was required because the TMC intercepts used volser number for direct reads of the record. This hasn't been required for some time. It doesn't hurt much either.

Tim, The attributes of our TMC are: LRECL: 340 BLKSIZE: 3400 RECFM: FB ALLOCATED CYLINDERS: 1,500 USED CYLINDERS: 465 Like Dave, I don't have any specific reasons why. I would be willing to bet that the small BLKSIZE is one reason why some of the CA-1 maintenance jobs run for awhile ( probally sequential reads ).
