You don't have to. Use this:

  get value("myfuction()",this card)

The second part ("this card") should be the script that holds the 
function; it may be the stack, a button, whatever. Put the correct 
script location in the second parameter.

Command handlers can take multiple parameters too. The two are basically 
the same, with the exception that functions more easily return values. 
You can return a value with a command handler as well, but then you need 
to check "the result" in the calling script to see what came back.
