when I wars responsible for application software 10 and/or 20 years ago, I did 
my usual low tech, basic utilities solution.  I'd do a 'listd hist' on the 
member names and store the results.  programs were compiled when they went from 
dev to test, and copied from test to prod/staging.  yes I wrote a lot of rexx 
code and used 'listd members' to process a pds in a loop thru the names.  
didn't use a lot of pdse since I maintained the libraries and didn't have any 
issues, but those hist stamps were reliable.  I could check the history stamps 
anytime, but always when software was promoted.  then me and my software got 
replaced by cots...

Hi,

It's possible to sign a program with a certificate. If you enable the 
certification this program is verified during LOAD for integrity and you can be 
sure as program author that the program ist the one you created and is not 
modified.

If you copy the program from a PDSE to a normal PDS no verification can take 
place cause the information nessesary to verify is not kept the PDS. 

As far everithing works as documented.

My question: Am I able to verify if the program runs as "signed program" and is 
verified or if the program runs without verification. I didn't find any hint in 
documentation.

Thanks,
Josef
