Image_Verification_in_a_Pipeline

   In a pipeline, image verification is turned off by default, even
   when the command SET VERIFY=IMAGE is executed before the PIPE
   command is entered. This prevents duplication of data records
   going through the pipeline.

   To turn on image verification in a pipeline, an explicit SET
   VERIFY=IMAGE command must precede the pipeline segment command.
   You can use a subshell to do this, as follows:

   $ PIPE ... | (SET VERIFY=IMAGE ; ...)  | ...
