The first word in each client’s command list error data area contains the
status/error code for the first command in the client’s command list. Each
successive word in the command error list is associated with the next command
in the list. Therefore, the size of the command list error data area depends on the
number of commands defined.
The structure of the command list error data area (which is the same for all
clients) is displayed in the following table:
Offset Description
0 Command #1 Error Code
1 Command #2 Error Code
2 Command #3 Error Code
3 Command #4 Error Code
