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 Client Command List. Therefore, the number of valid error values is
dependent upon the number of commands defined.

Clients) is displayed in the following table.
