    In looking through the scripts for the Built-In Section Marker, I found that one script is returning values to another without any corresponding parameters (if you want to look, it’s the values ‘t1’ & ‘t2’ in the macro “Marker Link Parameters” being returned to “Section-Elevation Marker Macro.”)

    I tried to mimic this behaviour in a couple of my scripts to avoid creating unnecessary parameters, but it doesn’t work. What’s the trick?

    The returned parameters is just a “simple value list” in the specified order – it is not really “parameters”, just variables in the scripts.

    You need to declare the list of values to be returned at the end of the called macro’s script, like this:

    end value1, value2, value3

    Then in the caller object, you need to specify the variables to where you want to fill in these values:

    call “samplemacro” parameters …..
    returned_parameters variable_receives_value1, variable_receives_value2, variable_receives_value3

    I hope it helps, if not, please upload a sample which you can’t solve. (Upload in zip please, as gsm files are forbidden by the hosting service provider of this site.)
