IN a JCL if we give :
Code:

//* this is comment


obviously it will considered as comments...

But in many cases I have seen this :
Code:

//*+JTS RELEASE DATE=+001,TIME=05:15


and similar other statements where even though the third position of JCL has a * still that line is being executed, in this case, the job is held in que until it reaches that time.

So I want to know what's this special case in JCL. I have googled and not found any answers for this.

Thanks

Check the JCL Reference manual (link at the top of the page) for the JES3 command format. This only applies if your site uses JES3, not JES2.

There's at least one specific override that can be passed as a 'comment' card in JES2 that I'm aware of.

.. oh! and the line isn't executed.

Garry.

I faintly remember seeing something like this JCL at our shop, in which the statements with comments
//*+
were processed by scheduling system(which runs on JES2)

I could be totally wrong. :S
