>/tmp/x: ?warning: last char not newline

is a warning you get when you try to write a file that doesn't end with a
newline, the other message:

> I sometimes get the "?newline expected" error,

is provoked by a syntax error in a command in the sam (command) window. For
instance, try typing
   qx
(and a newline)
it expects nl after q
