Mainframe, MVS and zOS Discussion

Thanks Robert. I've seen some of the JCLs which had DUMMY coded along with the DCB parameters, which is confusing. I read, understand that they need the DCB and checked for syntax - but it sounds not very convincing that something which is used just for "being dymmy" needs to have real DCB...

Thanks Anuj & Robert.

But are slack bytes still needed/generated?

Hi,

Can any one explain me the difference between "DD DUMMY" and "DD DSN=NULLFILE". And when should one use DUMMY and when NULLFILE?

Inspiring it is.

Thanks Anuj.

Hi.

Can anyone please give me a reply advantage of 01 single item than 77 declaration?

Thanks,
Anil

LOL!

Where you can utilize your energies in positive ways, should be considered as the best job...I think.

Yes, I too loved it!
