ref: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2B690/17.1.4 <quote> If you specify a stepname as part of a relational-expression, the system first determines whether the step executed. If the step did not execute, the evaluation of the relational-expression is false. </quote> >From my intepretation of: "If the step did not execute, the evaluation of the >relational-expression is false.", I think that any relational expression >involving a flushed step evaluates to FALSE.
