===============================================================================
HP-42S program storage format
Suffixes of nn work as follows: 0-65 are 00-101; 66-7F are A-J, T, Z, Y, X, L,
M, N, O, P, Q, \append, a, b, c, d, e; 80-FF are IND versions.
Fn starts an n-character alpha string; the 42S uses special initial bytes (in
the 80-FF range) to encode those of its extensions to the 41C instruction set
that take a parameter; parameterless extensions are encoded using XROM
instructions (2-byte instructions with 1st byte of A0-A7).
Dunno yet how the offsets work (LBL "", END, GTO nn, XEQ nn)

TODO: what about 1F (W ""), AF & B0 (SPARE)?

Quick instruction length finder: 00-8F are 1 byte, except 1D-1F, which are
followed by a string (Fn plus n bytes of text, for a total of n+2 bytes).
90-BF are 2 bytes (but what about AF & B0 (SPARE)?)
C0-CD: if byte 3 is Fn, then it's a global label with a total of n+3 bytes (the
string has an extra byte prepended which the 41C uses for key assignment); if
byte 3 is not Fn (TODO: which values are allowed & what do they mean?) it is an
END, 3 bytes.
D0-EF: 3 bytes.
Fn: string, n+1 bytes. This includes 42S extensions with parameters (42S
extensions without parameters are encoded using XROM instructions (A[0-7] nn),
always 2 bytes).
