I remember in the old days, we had a little thing we used to call the NCR Tower XP. I was brought in as a consultant to see if I could improve the performance of some of the customer's more important reports. The first hour I was there, I changed any variable used for loop counters from int to register int. Instant 40% performance boost. I continued to work the problem for another week or so, and presented the client with my results. They were suitably impressed. Those were the days, my friends. When data processing staff were considered just a half-level below Wizard.
