  64LAN gives your C64 access to files on your PC  hard  disk  (similar  to
64NET). It uses a custom file format extension "L64",  which  contains  the
original C64 filename and attributes.

   Bytes: $00-0F: 64LAN file signature ("64LAN IDBLOCK ", with <CR><LF>)
           10-21: 16-byte filename of contained C64  file,  with  <CR><LF>.
                  Filename padded with $20 (spaces!)
           22-2C: Starting and ending HEX load addresses, with <CR><LF>
           2D-55: 39-byte comment #1, with <CR><LF>
           56-7E: 39-byte comment #2, with <CR><LF>
              7F: EOF marker, for text viewing
           80-81: Version number of  file  (high/low  byte  format),  Above
                  example provides a version of 09.65
           82-86: 5-byte CRC
              87: Origin of file:
                   0 - Real C64
                   1 - C64s emulator
           88-FF: Reserved for future use
            100-: File data starts here, without the original load address

  All the strings in the beginning of the file, from 00-7F  are  in  ASCII,
and delimited with <CR> and <LF> markers. This block ends  in  a  text-mode
EOF marker. This is to help with the viewing of the contents of these files
using the DOS "TYPE" command.
