[kepler-users] setting parameter in constant actor

[Christopher Brooks]

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
