Assuming that OPEN INPUT was done on each file, then this
could easily fail if this was a VSAM file. A DISP=SHR goes
only so far with VSAM. You need to check what the
SHAREOPTIONS (do a LISTCAT on the cluster) are set to.

A good point. I think these were ordinary sequential datasets not VSAM,
but I shall pass that point on. Thanks.
