It doesn't matter where I'm working, how skilled the staff is, whether it's new development or mature legacy systems, it never fails that every couple of years I come across the old (and I do mean old) 32-character limitations on character parameters passed from the command line. It's a simple issue, really, but one that still manages to confound us. It may be the greatest example in our community of how those who cannot learn from history (or steal from those who have!) are doomed to repeat it.
