Hi Dennis, What you want to do (augment an existing tag value) can't be done using j ust DTCPARMS-defined tags and values, because (for a given :type.server and :type.class pairing) any tag present in the 'server' entry overrides any same-named tag that exists in the corresponding 'class' entry -- the valu es for the two tags are not combined.
When I first saw your question, I had also intended to suggest use of the TCPRUNXT exit, but with it, you can't really do exactly what you've descr ibed... You can supply additional (or, replacement) tag/value overrides via the e xit (with some limitations, based on the exit call type -- SETUP or BEGIN), b ut there is no information provided with the current interface that allows inspection of the set of tags and values 'known' by TCPRUN at the point o f either call type. So, you can't modify or augment a tag value based on i ts current value. This is a design point that limits some usefulness of the exit, at least with respect to what you want to do. If you see the need for this capability, a formal request would be the avenue to pursue it. Though, having now given this some thought, there is likely a way to use the TCPRUNXT server exit (with a few updates) that would allow what you're interested in doing. I'll contact you off-line, after I've had a chance to see if my ideas for doing this pan out... Regards, Mark Cibula (z/VM TCP/IP Support)
