                      DS:DX      Pointer to filespec (ASCIIZ string)
 
       Returns:       CX         File's attributes, or
                      AX         Error code, if CF is set

       Returns:       AX         Error code, if CF is set
 
       Error codes:   1          Invalid function code
                      2          File not found
                      3          Path not found

                      (DOS 3.0 and above).
 
       Network:       To change any attribute bit other than archive,
                      requires Create access rights.
 
  --------------------------------------------------------------------------
 
    This function returns or sets the attribute byte of the specified
    file. To determine the current attributes, put 00h in AL; the
    attribute byte is returned in CX. To set attributes, put 01h in AL and
    the desired attribute byte in CX.
 
       Notes:         The CX register specifies the attribute of the file
                      you're creating, as follows:
 
                               CX         Attribute specified
                               00h        Normal
                               01h        Read-only
                               02h        Hidden
                               04h        System
                               20h        Archive
 
                      Sum the values to combine attributes.
 
                      Setting any of the bits other than the above will
                      generate an error.
