Actually SP doesn't have an else/otherwise/default/whatever you want to
call it technique for case statements.  EP does have an 'otherwise'
feature and my reading of 10206:6.9.3.5 is that like BP's "else" usage,
"otherwise" doesn't require a begin/end for statement sequences either.
  Or can someone tell if I am reading it wrong?  (Note especially, the
first example)

>(If GPC behaves wrong with "otherwise", that's another thing, I don't know.)

Ironically, gpc doesn't compile it with an "otherwise" in there (at
least with 970714) -- which *would* be a bug (IMO), but I don't think
that is at all what the original poster was getting at.
