{
Could somebody help me out here? I'm trying to Write a
Program that reads the File names and their attributes from
disk/drive.

Unit volLabel;

  Type String11 = String[11];
  Function  GetCurrentVolumeLabel : String11;
  Procedure DelVolumeLabel(CurrentVolumeLabel:String11);
  Procedure WriteVolumeLabel(CurrentVolumeLabel:String11);
  ( to change a volume Label: delete old, then Write new )
}

(* Implementation *)

Uses
  Dos;

Var
  oldir : String; { only For test Program }

Type
  ExtendedFCBType = Record
                      ExtendedFCBflag : Byte;
                      Reserved1       : Array[1..5] of Byte;
                      Attr            : Byte;
                      DriveID         : Byte;
                      FileName        : Array[1..8] of Char;
                      FileExt         : Array[1..3] of Char;
                      CurrentBlockNum : Word;
                      RecordSize      : Word;
                      FileSize        : LongInt;

                      PackedTime      : Word;
                      Reserved2       : Array[1..8] of Byte;
                      CurrentRecNum   : Byte;
