Calculating the size of many VSAM files.

Hi,
We are part of a team which is working on a migration project. In one of the process, we need to analyze the size of a many VSAM dataset. Is there some way out for this? Can we write some JCL to do such a task in a single go?
Any help on this would help us to move forward.

Use IDCAMS to extract the attributes for each VSAM data set (only Unix System Services in z/OS has files). Write the output into a data set.
Write a program in the language of your choice to extract the relevant data from the data set.

What is the relevant data you are referring to? Can you please help me about that? Are you referring to HURBA?

It really depends on what you mean by "size". HARBA gives the allocated while HURBA gives the used. Many times allocated is a better measure of size as the used may fluctuate.
