OUT and DO COND statements have the following differences:
An OUT statement is applied only if the job ends OK. DO COND statements are associated with accompanying ON statements and are applied only if the accompanying ON step and code criteria are satisfied.
An OUT statement appears in each job scheduling definition. No DO COND statement appears unless specified. To specify a DO COND statement, type COND in an empty DO field and press Enter.
DO COND statements are processed after OUT statements and can therefore override OUT statements.
MVS restart can only be requested from an OUT statement, not a DO COND statement.
