[Coco] DECB BIN file format

[Juan Castro]

I'm studying the BIN file format and found this:

http://lwtools.projects.l-w.ca/manual/x24.html

So I looked at the binary LWTOOLS generates for CaChars. Here's the
start of an hex dump of it:

00000000  00 00 02 00 00 f6 ad 00  08 25 77 d0 57 65 6c 63  |.........%w.Welc|
00000010  6f 6d 65 20 74 6f 20 43  61 43 68 61 72 73 20 31  |ome to CaChars 1|
00000020  2e 34 2e 30 0d a9 20 32  30 31 32 20 4a 75 61 6e  |.4.0.. 2012 Juan|

So... there's a block of 2 bytes that's being loaded at address 0000?
And those bytes are F6 AD? What's that for?

The block that comes after that is my program, that's OK. The
postamble is intelligible too. But what's with that 2-byte block?
