block_size

The block size. (n)

Discussion

The BLKSIZ qualifier specifies the RMS block size argument in bytes.

Tip

We recommend that you only use BLKSIZ for MAGTAPE devices or to alter the record size of a B submode output file. Use BUFNUM to alter the performance of sequential files. (Values less than the OpenVMS default of 16 cause a reduction in performance.)
