  TArtFormula provides two styles of programming: formula style and scripting style.
   The first style assumes that all statements have the form of function call. 
   The second style imply that you use common program language notation.
   For example: 

     block(defines('i','n'), set('n',1), series(set('i',1), val('i')<=5, inc('i'), set('n',val('n')*val('i'))),msg('5! = '+val('n'),'result',0)) 

   Is equal to:

   begin 
     var 'i', 'n' end;
     $n:=1;
     for $i:=1;  $i<=5;  $i++ do
       $n := $n*$i;
     next;
     msg('5! = '+val('n'),'result',0);
   end

   You can mix two styles in one program.
