                   INT 21,27 - Random Block Read Using FCB


       AH = 27h
       CX = number of records to read
       DS:DX = pointer to an opened FCB


       on return:
       AL = 00 if read was successful
          = 01 if EOF (no data read)
          = 02 if DTA is too small
          = 03 if EOF (partial record read)
       CX = actual number of records read


       - allows random access and sequential reading of a group
         of records from a file opened with an FCB into the DTA
       - FCB must be setup with drive id, filename, extension
         record length and random record number before call
