I remember hearing some people expressing their disappointment at the fact that LISTSERV wouldn't run in an XA-mode machine a couple years ago, but I don't remember who it was. Anyway, I believe that the version I am now using on LISTSERV@SEARN should be XA-tolerant (it can't be XA exploitive since REXX isn't), but I cannot test it on my 9370 and XA support for the server is quite low on my list of priorities anyway (the reason I dual-pathed LSVIUCV is to allow LDBASE to work in XA mode *user* virtual machines). If there are sites which are worried enough about running their server in XA mode to be willing to try this code out (with the understanding that I won't be able to reproduce problems locally), just drop me a note.
