In Ptolemy, the Const actor is a Parameter. To refer to another
parameter, first create the parameter and then change the Const
value to the name of the parameter with no #
For example,
Drag a Parameter actor in
Change the name to foo_bar
Drag a Const actor in
Change the value of the Const to
foo_bar
StringConst extends Const but puts the value into string mode.
There, you would use $foo_bar.
To use a parameter value in MultiplyDivide, use the Const actor,
but don't prepend the parameter with $. Also, be sure
the parameter exists before trying to use it.
Hope this helps.

hi,
i need to use the parameter in 'constant' actor but when i define value
field as $parameter_name, it generates error. i think it is only accepts
numeric values. Is it possible to set parameter value into constant actor?
Or, how can i use the parameter value in 'Multiply or Divide' actor?
Because i use the 'constant' actor to define the parameterm in it.
best wishes,
ufuk
