Presently, CP6 is supported, CMS6 isn't. If it turns out that I am able to provide support for CMS7, CMS6 will become supported for problems that can be reproduced under CMS7, and otherwise unsupported. As you probably know, there are tapes and tapes of fixes to CMS6, which have to be applied with procedures which don't always do what they say they do... This is the main reason for not supporting CMS6 today (another one being that I have no access to CMS6). When a DISK LOAD gives you an undocumented error on a perfectly legal file, just because someone in IBM decided that the CMS6 DISK LOAD needs only support files generated by the CMS6 DISK DUMP (it can't clear the last few bytes in the last card in the deck by itself), you start wondering what kind of an application support base you are dealing with. These are the EASY errors, too - the ones that prevent you from having the opportunity to actually load and fire up LISTSERV. Eric
