- That's interesting--I had no problem upgrading from dBASE III+ to dBASE IV on
- an 8 MHz XT. It did take more time to load up than dBASE III+, but I don't
- recall that the application was any slower.

- My impression was that the Assistant in dBASE III+ was actually more intuitive
- than the control center in dBASE IV. However, I was writing my own
- application, and bypassing both the Assistant and the Control Center, so it
- didn't matter to me. I did run into one true bug with dBASE IV (the first
- release) which I was able to program around. We went with dBASE IV because we
- needed to have more files open simultaneously than dBASE III+ allowed us. My
- client has since upgraded his AT&T 8088 machine to a 486, and is quite happy
- with the way dBASE IV does disk caching.
-
- At the time dBASE was "it"! If I had to do it today, though, I might choose
- something else to do it in. I don't know--its been some time since I've done
- any database programming.
