By default, job steps within the IF/THEN/ELSE/ENDIF statement construct do not execute when

• An abend occurred, and
• the IF/THEN/ELSE/ENDIF structure containing the job steps does not specify the ABEND, ABENDCC, or ¬ABEND keyword. If any of these keywords is specified (with or without stepname or procstepname), the job steps do execute despite the abend.
• The step's COND parameter, if any, does not specify an abend condition (COND=EVEN or COND=ONLY).
