If you are Pdox for DOS you can actually write a program to use Tutility to verify and rebuild your tables unattended. That what I did when I was doing Pdox DOS, a looooong time ago.
If you are using later versions of Pdox for Windows, you will have to buy or write your own tutility.
If you do Delphi, there are quite a few sharewares available. After checking over a dozen of them, I found tutil32d.zip worked for me.
Good Luck
