RE: API CEEDOD and CEE0502 Missing operational descriptor.

No, he's saying in the case of CEEDOD do not use *NOPASS.  See the API
document
http://publib.boulder.ibm.com/iseries/v5r2/ic2924/info/apis/CEEDOD.htm.
The document specifically states the feed back parameter is omissible
not optional.

Thanks, Matt

So... are you saying that *NoPass should never be used? ever? for any
programs?  I've created a few programs where the program was prototyped
this way (*NoPass).  "Luckily" I haven't experienced any problems.

Doing this will cause the API to try to read the feedback structure from
an area of memory that's undefined.  This could cause data to be
overwritten in areas of memory that don't belong to your program!  This
could cause strange errors like other programs in the job crashing, or
operating system functions failing, or variables seeming to have
"garbage"
in them.

Granted, in most cases, you'll be "lucky" and get unused memory.  Since
unused memory is normally set to x'00', it'll act just like *OMIT.
Until
one day, years from now, someone will run this code and be "unlucky" and
get memory that something else is using.

Please, please don't use *NOPASS for this.  The correct code is
OPTIONS(*OMIT) as Barbara put in her article, and as the OP originally
posted.
