Among other reasons, I want to accomplish this without having class1's structure be defined in main so that other methods, functions, and procedures can operate on the field values as they change during a calculation

You can have your class inherit IDL_Object:

http://exelisvis.com/docs/IDL_Object.html

See the "IDL_Object and Property Access" section on this page:

http://exelisvis.com/docs/WhatsNew_in_8_0.html

Also, look at "Automatic Class Structure Definition" on this page:

http://exelisvis.com/docs/creating_an_object_class_1.html

You are nearly there.
