(For certain twisted, messed up definitions of "love.")

Type this program in a CoCo 3, then save it to disk. It won't run, but it
will tokenize every keyword, no problem.

10 LOF
20 MKN
30 AS
40 LPEEK
50 BUTTON
60 HPOINT
70 ERNO
80 ERLIN

These are (according to the Unravelled books) secondary tokens FFA5 to
FFAC. So they should show up in the binary. BUUUUUUT if you bring the
binary .BAS file to a PC and explore its contents with an hex editor, this
is what you'll find:

The tokenization is LIES! There's a weird off-by-one error in there
somewhere. And I have to reproduce it or the keyword preservation in my 16K
HDB-DOS won't work! I'll have to introduce a dummy keyword at $FFA9.

Every CoCo3 SECB program in existence was saved with these wrong tokens, so
I'll have to preserve the wrongness.
