As a slight aside: I knew about the 'bc' (bench calculator) program in Linux/Unix, and I also knew there was a 'dc' (desk calculator) in Linux/Unix
What I didn't realise, and have only just learned, is: * dc is the original and runs RPN * dc predates the C programming language; it is the oldest surviving Unix program, and Ken Thompson has opined that it was the first one written (in B) for the PDP-ll running Unix * the BC program is written on top of dc. https://en.wikipedia.org/wiki/Dc_(computer_program) On Tuesday, May 2, 2023 at 11:04:55 AM UTC+1 Edward K.
