RE: Logical File with Field being substringed as a Key

["Debbie Panco" <dpanco43@xxxxxxxxxxxxx>]

Rob,

Yes, that's cool.  I tell ya though, the sequel book that I have is terrible
at describing it's functions.  I read the section on Decimal and it is just
awful.  It really doesn't explain it very well.

Thanks.

Debbie
