To prevent a job from being selected and printed before you have a chance to review it with IOF, you can hold all of the sysout data sets for the job. You can then use the PRINT function under the IOF Job List to release all of the data sets for printing. You may also selectively release and cancel the sysout data sets individually with the RELEASE and CANCEL functions under the IOF Job Summary.
To hold a sysout data set, you can either specify HOLD=YES on the DD statement for the data set or specify a held sysout class. Check with your technical support or user services staff to find out which sysout classes are held at your installation. In order to hold the system messages, output JCL, and job console log data sets you must specify a held sysout class in the MSGCLASS parameter of the JOB statement.
Specifying sysout=* for a sysout data set causes the class for the data set to be determined from the MSGCLASS value. Specifying sysout=* for all of your sysout data sets in a job allows you to completely control the hold status for all of the data sets with the MSGCLASS parameter of the JOB statement.
As an alternative to holding sysout data sets, you can simply route the printed (and possibly punched) output for your job to a JES2 destination that does not actually correspond to a real JES2 remote terminal. Contact your technical support staff to find out the name of a destination that can be used for this purpose. Include a /*ROUTE statement in your job to establish the dummy destination:
/*ROUTE PRINT FETCH
Note that FETCH is just an example of a destination that might be established by your technical support staff for this purpose.
The job will not be selected for printing and, therefore, will be available for review with IOF.
After reviewing a job's output with IOF, you can cause it to be printed at your default print destination by using the PRINT function under the IOF Job List (or the PRINT operand of the RETURN or EXIT commands).
To establish a default print destination, enter P.1 on the IOF Option Menu. This will display the User Profile Menu, which will allow you to specify a default print destination.
