!TITLE Comments

    A  semi-colon  does  not  terminate  a  comment  -  it  can  only be
terminated by a newline.  Comment statements can be continued by use  of
%c (or by being broken after a comma).

    A  new  type  of  comment  is  introduced;  it is delimited by curly
brackets, '{' and '}'.  Such a comment can appear  between  atoms  of  a
statement  (an  atom  is  an  identifier, constant, keyword, operator or
delimiting symbol).

Example:
          A(I{month}, J{salary}) = 927.4

    The comment text can contain any symbols  except  '}'  and  newline.
The  closing '}' can be omitted, in which case the comment is terminated
by the next newline.

    {...} comments are particularly  useful  for  explaining  own  array
initialisations.
