The final comments must come from ''IDL guru'' David Fanning,
'' Don't worry about it. Everyone I've ever known who leaves an IDL programming class (including the instructor!) laments about how they are going to have to spend the next two weeks re-writing their programs. It's an on-going and never-ending process.
Do what you can, but don't dwell on it. Just try to write better programs in the future. At the end of a career no one wishes they had spent more time revising their programs. :-) ''
