Hi Georg,

Thanks for your response. I just don't understand how to implement it.
In ada we have a function definition like:

procedure DynamicArray is
begin

    -- Function body stuff here...
    -- Where does Argument_Count come from?
    -- Where does Argument (0...numArgs) come from?

end DynamicArray;


Thanks,
Mark
