Below are some examples of the return statement:

func f()

    // This returns the result of the expression 3*2

    return 3*2;

endfunc

func g()

    // This returns the string "123"

    return "123";

endfunc

func h()

    // This returns the empty str ""

   return;

end

Note it is not illegal to return a value from the onsignal function, but the return value will be ignored lost when control is returned to the main program.    Therefore it is more correct to just use a return statement without a return expression:

onsignal

    return;

endonsignal
