Consider an ideal situation where I have a step in a proc using 255 datasets(PS) in concatenation. If I have to ignore only the 3rd dataset in concatenation while still picking the rest of the 254 datasets for processing from my JCL, how would I do it?
One round about way, but relatively easier way I see is to create an empty dataset and override it as below.
As far as I know for standard io there is no other way to do it than you have shown. The "trap" in an Interview Question is that if you DUMMY/NULLFILE it you get EOF at that point and 4th-and-onwards don't get read...
