SAS debug system option

System-level options. These options control the
amount of diagnostic output you receive, and the
source statements that are displayed in the Log. They
also tell the SAS Supervisor how to react to abnormal
conditions – that is, whether a particular event (such
as an unknown format) should be considered an error.
