I did that once. We had a program that read paper tapes, producing a detail listing as it did so. It also built a summary table in memory. After the last tape was read, the program sorted the accumulated data - using a bubble sort, no less. The machine sat there for 60 seconds, the CPU grinding like mad, before it went into the summary report. This was a small machine with no spooling, and each detail record was being listed on a 600-lpm printer. I realized that this gave me a full 100 milliseconds to process each record, whether I needed it or not. So I re-worked the program to build the summary table with an insertion sort; there was no penalty in wall-clock time, and the table always remained in sequence, so after the operator signaled that the last tape has been read, the program instantly went into the summary report. Being the devious sort that I am, I gave the new version of the program to the operator without telling him about this modification. And predictably, I got an anguished cry that the program wasn't sorting anymore. "Check the report," I said. "It's in sequence, isn't it?" To this day I see examples of people locked into the mindset that if something doesn't take a long time, it can't be right. Sometimes they're right, but other times they're barred from realizing that a better algorithm can work miracles. > Good times.
