Full_Description

   Use the /BUCKET_SIZE qualifier with relative and indexed-
   sequential output disk files to specify OpenVMS RMS bucket size
   (the number of 512-byte blocks per bucket). If the output file
   organization is the same as for the input files, the default
   value is the same as the first input file bucket size. If output
   file organization is different, the default value is 1. The
   maximum number of blocks per bucket is 32.
