Hi, I've created an class object. In the ::init method I load some data into some pointers. I want to create another method, ::change_data, that would simply load another set of data into the object. I'm not quite sure what would be the best method, but here is what I was thinking of: calling the ::cleanup method to remove all the pointers calling the ::init method that contains all the code to load the data I've tried the following... but of course this doesn't work pro shoalsObject::change compile_opt idl2 shoalsObject->icleanup shoalsObject->init end Any idea of how I could do something like that ?
