And they are OO to begin with, that is, the user has to instantiate an object to work with them. BCB(Delphi) File I/O do not have object to operate. This is different with MFC's CFile class. > > FileOpen() always opens the file at the beginning of the file.

However, when one has to open a *NEW* file, the FileCreate() does not have such access mode to select. Do I have to create it by FileCreate(), then FileClose(), and then FileOpen() again to allow the file to work in the desired fashion? Regards, Patrick
