IDC01723I ERRORS MAY BE DUE TO CONCURRENT ACCESS

Explanation
The catalog OPEN indicator or AMDSB indicates that
the data set may have been updated during EXAMINE testing. Some or
all of the detected errors may not exist.

Programmer response
If possible, run EXAMINE again without any
users having the data set OPEN for output. If this is not possible,
ensure that the data set is not updated during testing.
