Space problem issue

Hi everyone:

I would like to know the best way to calculate space, every time that I am creating a PO dataset. Example: If I want to create a dataset with 40 members. What would be the best way to calculate the space.

I would like to apply it when I am working with JCL and TSO as well.

Thanks everyone

Hi,

The size of PO dataset will depend on the size of members, not the number of them. and you will have to know the total size of all members to allocate the PO with exactly the same size. If the members are constant, then you can write some utility to findout the space.

or did I misunderstood your query?

Hi,
Its not possible to find out the size of the DS(PO in nature) in advance. For that u have 2 assume the size of the members. What VINODC has said I think is perfect 4 ur query.

Hi friend,
first you have to think that,
how much amount of data you have to fetch (or) code in to the dataset,
for example you have to fetch 500 bytes of data according to that we have to allocate the size of the dataset.

Corretions welcome,

Hi :

You can use the command TSO SPACE which gives you the estimated space needed for the DS.

Thanks,
