Is there any relation in spanned records and control interval split?

What kind of relationship do you think exists? A spanned record is where the record length is longer than the CI size. A CI split occurs when there is a KSDS record to be inserted but there is no space in the CI for the record.

Thanks Robert, I was thinking as if the spanned records are like fixed-block or variable-block concept or they come in to the picture only whrn CI split happens.

You will only get spanned records when, as Robert has said, you record-length is larger than the CI size. This will require more than one CI to contain the data,.

CI splits are a different thing, nothing to do with spanned records.

I've never even considered using spanned records for VSAM, not come across anything that uses it.

What are you trying to do?

As William said, spanned records really have nothing to do with splits. A spanned record can be fixed or variable length in VSAM.
