Use the LOOP EXECUTOR command to test the executor node in the
 network.  The parameters are optional and can be entered in any
 order.  You can supply explicit access control information for
 the LOOP EXECUTOR command.  This command does not apply to VAX
 PSI.

1  –  ACCOUNT

 Identifies the user's account for access control verification
 for the executor node.

2  –  COUNT

 Specifies the number of blocks to be sent during loopback
 testing over the executor node. The count must be a decimal
 integer in the range of 1 through 65535. If the parameter is
 omitted, only one block is looped.

3  –  LENGTH

 Specifies the length (in bytes) of the blocks to be sent
 during loopback testing. The length must be a decimal
 integer in the range of 1 through 4096. If the parameter is
 omitted, a block length of 4096 bytes is used.

4  –  PASSWORD

 Identifies the user's password for access control verification
 for the executor node.

5  –  USER

 Specifies the user's identification for access control
 verification for the executor node.

6  –  WITH

 Specifies the type of binary information to be sent during
 testing. Three types of data can be sent:

                 MIXED
                 ONES
                 ZEROS

 If omitted, a combination of ones and zeros (MIXED) is sent.

7  –  Example

      NCP>LOOP EXECUTOR

          This command initiates a loopback test on the executor node.
