     The SET RMS_DEFAULT command in this example sets the multiblock
     count for disk file I/O at 24 for user programs that do not set
     the multiblock count explicitly. The command applies only to
     the current process.

     The SET RMS_DEFAULT command in this example defines the default
     multibuffer count for I/O magnetic tape operations at 8.

   3.$ SET RMS_DEFAULT/BUFFER_COUNT=7/NETWORK_BLOCK_COUNT=16/SYSTEM

     The SET RMS_DEFAULT command in this example defines the
     systemwide default multibuffer count at 7 for all sequential
     file operations on disk, magnetic tape, and unit record
     devices. The command also sets the network block count at 16.

   4.$ SET RMS_DEFAULT/EXTEND=50/INDEXED/BUFFER_COUNT=5

     The SET RMS_DEFAULT command in this example sets the default
     multibuffer count for I/O operations on indexed files at 5.
     It also defines the default extend quantity for sequential
     I/O operations at 50 blocks. These defaults apply only to disk
     operations for user programs that do not set the multiblock
     count explicitly. These defaults are limited to the current
     process.

   5.$ SET RMS_DEFAULT/QUERY_LOCK=DISABLE

     The SET RMS_DEFAULT command in this example requests that query
     locking be disabled for the duration of any file opens done by
     images within this process for any read ($GET or $FIND) record
     operations that have both RAB$V_NLK (no lock) and RAB$V_RRL
     (read-regardless) set in the RAB$L_ROP field of the RAB (Record
     Access Block).
