The problem I have with COND= is that it's back-asswards. First, it
specifies conditions to NOT run the step. You have to keep in mind that
with multiple conditions, any TRUE condition means don't run the step.
Except for ONLY & EVEN, which specify conditions for which the step *will*
run.
Gil,
I attach a discussion about the IF/THEN vs COND= we had in 2011.
That COND= BTW was for a real case of a chemical company running its
payroll 100+ step job on our mainframe, but with a COND=(4,LT) on its
job card. Each time one of its jobsteps hit a CC GT 4, the job ended and

Again and with all due respect, progress is made not by blunting the
tool but by sharpening the user.
"IF/THEN" does not handle all boolean AND/OR/NAND/XOR and
steps-not-executed conditions.

Once I learned of the IF/THEN statements for
JCL I never used COND= again. IF/THEN is much
easier to use and to explain to new people.
I have seen many people code COND statements
incorrectly because they did not acually
understand how they worked.
