Richard,
I can confirm the non-functionality of the skipntcrc option in ADSM
v.3.1.0.7 (and before), as this was a side issue in a PMR we had open with
IBM a while back - as I understand, instead of ignoring the CRC value, ADSM
actually sets it to zero. We had a fixtest (which we used for testing
purposes only I hasten to add) - I haven't checked the website to see if
that fix has found its way into any official fixtest release prior to v.3.7
going out, but I would tend to agree with the other Richard anyway in
suggesting using retention parameters to get around your problem.
Cheers,
Andrew Taylor,
