32D

Explanation
A program requested an overlay.  In answer to the
request, the overlay supervisor was using program fetch to load a
program segment from the library.  Fetch found one of the following: A record of an incorrect length
An uncorrectable input/output (I/O) error

Note: Overlay programs run only in 24-bit addressing mode,
not in 31-bit addressing mode.

System action
The system abnormally ends the program that requested
the overlay.  The system writes an ABEND dump, if a dump DD statement
is provided.

Operator response
If messages show an I/O error on the device
containing the overlay segment, run the job step again.  If the I/O
error recurs, contact hardware support.

Programmer response
If messages did not show an I/O error, link
edit and run the program again.
