The internal structure of file variables (FileRec and
TextRec in BP's Dos unit and TFileRec and
TTextRec in BP's WinDos unit) is different in GPC.
However, as far as Text File Device Drivers (TFDDs) are
concerned, GPC offers a more powerful mechanism. Please see the RTS
reference (see Run Time System), under AssignTFDD.
