Hi,

I have one doubt. MSGCLASS is suppose to direct the SYSOUT to a particular destination, be it the spool or the printer etc. Say I have MSGCLASS=D where D is directed to the printer. Now if I have SYSOUT=A where A is some other destination, which one holds precedence?

Cheers

Hi A,

Your SYSOUT=A data will go to the A Queue, the job msgs to the D Queue.

The sysout data set is processed according to the following processing
options, in override order:

- The options specified on this sysout DD statement.

- The options specified on a referenced OUTPUT JCL statement.

- The options specified on a referenced JES2 /*OUTPUT statement or on
a JES3 //*FORMAT statement.

- The installation default options for the requested output class

Note: If a sysout data set has the same class as the JOB statement
MSGCLASS parameter, the job log appears on the same output
listing as this sysout data set.

abracadabra,

Your assumption is not true.MSGCLASS parameter to assign the job log to an output class. The job log is a record of job-related information for the programmer. Depending on the JOB statement MSGLEVEL parameter, the job log can consist of:

1 Only the JOB statement.
2 All job control statements.
3 In-stream and cataloged procedure statements.
4 Job control statement messages.
5 JES and operator messages about the job.

Sysout=A is a parameter that can be used on any DD statement to specify output class A. Sysout is basically used to display informational messages like execution time data, control cards/options, etc. All your DISPLAY stmts are shown in Sysout. Some of the utilities like SORT use sysout dd statement to display informational messages.

When you code //SOMEDD DD SYSOUT=* , it will default to the JOB MSGCLASS output class.

When the JOB statement and sysout DD statement both specify the same output class, the job log and data set OUTDD1 are written on the same output listing.

check this link for a detailed explanation of the MSGCLASS parameter.

abracadabra,

The output class definitions vary from shop to shop.The default is based on the source of the job: The system places the job log in the same output class as the installation-specified default class for the particular card reader, work station, or time-sharing user that submitted the job. The installation default is specified at JES initialization.

Hope this helps...

cheers
