== Blocks ==
=== Header block ===
The header, which is 17 bytes long, is as follows:
''(Of course on the tape there are two more bytes: a 0xff -- marker of data block -- at the beginning and a checksum byte at the end.)'' Note: although the array name is saved, you cannot just ''LOAD "" DATA'', you have to explicitly say where to load: e.g. ''LOAD "" DATA w()'', but you can use any letter regardless of the original name.
