The BTP product was born to remove the drudgery from Btrieve programming. BTP
includes a number of sound data structures/objects, including these four:
TRecMgr, BFile, BFixed, and BFileExt. TRecMgr and BFile are base objects;
they are direct descendants of TP6's TObject. BFixed and BFileExt are both
direct descendants of BFile.
