Error transfer

Procedures called in the background are executed in separate jobs; for this reason, error information cannot be transferred by means of variables or command return codes.

In this case, job variables are provided for storing error information. Compatibly with non-S procedures, user switches can also be used in S procedures. Other jobs can access both job variables and user switches.

Differentiated error information can be transferred by means of job variables, since the contents of a job variable can be up to 256 characters long. (For more information on job variables, see the “Job Variables” manual [5].)
