Parameter Attribute Description

This is where the user is informed about whether errors have been recog-
nized during job allocation. Each result bit has been assigned a job. The as-
signment corresponds to the one of the P3 input parameter. A set result bit
indicates that the job which has been addressed with the same bit number in
P3 could not be allocated. In addition, a detailed error code is output in the
first word of the relevant job block.
