The last digit in the block identification code indicates the number of commands
to process. For example, a block identification code of 5003 indicates that three
commands are to be placed in the queue. In this case, the first three of the six
available Command Indexes will be used to determine exactly which three
commands will be added to the queue, and to set their order of execution.
Values to enter for the six Command Indexes range from 0 to 99 and correspond
to the MNET Client 0 Command List entries, which are numbered from 1 to 100.
To determine the Command Index value, subtract one (1) from the row number
of the command in the MNET Client 0 Command List, as seen in the Command
Editor window of ProSoft Configuration Builder (PCB).
The module responds to a Command Control block request with a response
block, indicating the number of commands added to the command priority queue.
