Do you mean the actual average of all records in the file or the record length that JCL or IDCAMS would expect to find ?

Use Sort to sum the lengths and count the recs and gen a trailer with the total lengths divided by the total count.

Hello,

If you run a sort, it will give you both the byte count and record count of the sorted data. If you divide, you get the average length.
