Hi,

I would likem to know the meaning of catalog data set and non catalog data set. And when do you actually use these data sets.


Thanks

Hi breentha,

Data sets are cataloged when we give disposition as catlog. [ie.disp=(new,catlg)]
So when we go to 3.4 option in ISPF menu and provide the Data set name(DSN)
we will be able to view our dataset.
In other hand if we dont give disposition as catlog then it will not be listed in 3.4
option.
Data sets can be used in many ways like we write a jcl in the dataset, it can also
be used as input or output files
