Unfortunately, I do not have any such scripts. If they mattered to me, I have fixed them so long ago that I do not remember the event.
Perhaps it matters that I view programming as an activity rather like inhaling. Inhaling is an important part of breathing, but if you never exhale you will not do so well. Put differently, I think there is an activity related to programming which involves discarding code that's not useful. Code is easy to generate... Finally, one of the things I most value about J is that it's concise enough that I can do useful transformations on bodies of code with relatively low amounts of keyboarding. I can think of all sorts of automated transforms, but ultimately it's my understanding that's the valuable thing for me. -- Raul On Wed, Feb 22, 2012 at 4:54 AM, Linda Alvord <lindaalv...@verizon.net> wrote: > For This Challenge Only!
