We currently run LISTSERV 1.8b under VM/ESA 1.2.2 with CMS 11 in an XC mode machine with 24 meg. of storage. We plan to convert to LISTSERV 1.8c under VM/ESA 2.2.0 with CMS 13 as part of a year 2000 compliance project. LISTSERV 1.8c is documented to run in CMS 12. LSoft, Inc. believes it should run in VM/ESA 2.2.0 with CMS 13 but does not know of any one who is doing it. Is anyone running LISTSERV 1.8c under VM/ESA 2.2.0 with CMS 13? If so, any problems, especially in regard to year 2000 issues? Thanks for any info, John Hammond
