Dear Marga,

Cinderella SDL does support the present operator. However, a general rule in
SDL-2000 is
that operators start with lowercase, so the operator name is "present"
rather than "Present".
But this might not be correct. I checked (the (11/99) version of) the
SDL-2000 recommendation and
found that the text defines present starting with upper case. Maybe Rick
could respond about what is correct?
