Hi keerthi

step2 executes only if step1 executes correctly ie return code of step1 is 0

as 0 LT 0 is not true...step2 executes

if step1 return code is non zero ie..4 suppose
as 0 LT 4 is true---step2 will not execute

Thanks

The more commonly used equivalent is:

Hi,

I suppose step2 will be executed each time if the condition code for step1 is zero or greater than zero....And if the condition code for step1 is less than 1 then step2 will not be executed and that will never happen since no condition code is less than zero.

If i am wrong then please tell me.

Thanks

Aishwarya,

when ever the condition code is false only step2 will execute.
For example
(0,LT,8) in this case condition is true and step2 never executes. So step1 should always return a zero code then only step2 will execute. If it returns non zero return code then step2 never executes.

We don't have any negative return codes in jcl

Hope this will help you

This might help. I know it helped me.

Read "cond=(0,LT)" as:

If zero is less than any pervious RC, DON'T execute this step.

Another example:

Read "cond=(0,LE)" as:

If zero is less than or equal to any pervious RC, DON'T execute this step.

This one can be used to effectively DELETE the step from the jobstream. When you want it back restore the original COND clause.
