--- Comment #7 from Sylvain Korzennik <skorzennik at cfa dot harvard.edu> --- Thanks for following up, Steve. I gave up on gfortran when the 64b record marker made it unusable for me. I'm not surprised it was fixed, but this pointed to poor decision making and ignoring the need to backward compatibility. When you don't need to sell your product, your "customers" needs might not be your highest priority. Backward compatibility is a wide spread problem, in commercial products (trust me, some have hear mn more than once) and in 'free' ones (the Python 2.x vs 3.x debacle comes to mind). When you've been at it for 3 decades, it matters. PANDORA can be downloaded, and it is ugly coding (I know the author, he retired a while back and I was for a while helping maintain the code), but it may be a good example why you can't easily all a sudden switch to new rules, and why we maintain multiple versions of multiple compilers. Have a great 4th of July, stay sane, safe and healthy, 6+ft away! Cheers, Sylvain
