I  don't  know in  which  language  I  should  write my  error  messages.
"Uppercase  english not  available" refers  to NLS,  you know  this thing
which gives you error messages in your  local language and broke a lot of
programs,  IBM and  non-IBM alike.  Well LISTSERV  is not  able to  parse
messages  in german,  so  it  tries to  get  the good'ole  SP4-compatible
language, UCENG. If not available, it displays the said message and tries
AMENG. No AMENG, no LISTSERV (immediate LOGOFF).
