Actually, Netview had to keep up with the competition and messages from any source is a PI. CICS has a TDQ for messages. IMS has it's messages from another source than console messages. Even messages within listings are considered PI otherwise why are DFSORT messages a migration consideration? > Not according to IBM's use of the term "programming interface".

I've had very upset customers have me discuss utility output with IBM support and found IBM support to be extremely understanding and helpful. They don't want to be mean to customers if they can avoid it. Especially when it takes very little effort. I've explained how to use existing tools (HOLD AO, migration considerations, ...) and that customers need a small warning to avoid the pain of reviewing every PTF for that product. I ask them to discuss with the Netview group for their position. I don't know that it worked because I don't hear from them again but I like to think I wasn't wasting my time. >If an application chooses to rely on the listing or message beyond that, >it does so at its own risk, as changes can occur without notification. >Still, such changes would be uncommon. Customers have no choice but to take the risk with utility output (e.g. CICS (CEMT, CSMT, ...)., DFP and more). >Peter Relson
