The procedures FindFirst and FindNext use the typed definition of
     SearchRec to scan directories.  The information about each file
     is returned in SearchRec.  The "Fill" field is reserved by DOS
     and should not be modified.

                      SearchRec = Record
                         Fill : Array[1..21] of Byte;
                         Attr : Byte;
                         Time : LongInt;
                         Size : LongInt;
                         Name : String[12];
                      end;
