The debug data display has been used to author (most?) platform/*/main.c modemaps, which in turn are (only?) used by mode_get()....mode_get() in turn is (only, I hope) used by CHDK to check PLAY/REC modes (and I guess swivel screen status), but not the modemap.
Not quite true. There are some checks for manual, sports, stitch assist etc. As I noted in the mantis issue linked above, the whole system basically sucks. Most of the modes are meaningless to CHDK, but in some cases they aren't.

And yes, mode_get reads the propcase value into an int as does shooting_get_prop().
No, shooting_get_prop reads it into a short. This gets returned as an int, at which point it gets sign extended. This is probably wrong.

mode_get (on the platforms I checked anyway) reads into an int to start with.

Another fun one, s2is
Code: [Select]
    { MODE_AUTO,                5 },
    { MODE_P,                   1 },
    { MODE_TV,                  3 },
    { MODE_AV,                  2 },
    { MODE_M,                   0 },
    { MODE_PORTRAIT,            6 },
    { MODE_NIGHT,               8 },
    { MODE_LANDSCAPE,           7 },
    { MODE_VIDEO_STD,           16  },
    { MODE_STITCH,              0xFF },
    { MODE_MY_COLORS,           4 },
    { MODE_SCN_NIGHT,           14 },
    { MODE_SCN_CHILD,           0xFF },
    { MODE_SCN_PARTY,           13 },
    { MODE_SCN_GRASS,           9 },
    { MODE_SCN_SNOW,            10 },
    { MODE_SCN_BEACH,           11 },
    { MODE_SCN_FIREWORK,        12 },
    { MODE_SCN_COLOR_ACCENT,    0xFF }
modemap is currently only used to lookup from canon mode to CHDK mode.  So if the 0xFF values are what canon actually uses, then MODE_STITCH will be returned for all of these.

According to canon this camera does have a stitch mode, so these aren't just (misguided) placeholders for non existent modes.

Anyone have one of these and want to test ?

{ MODE_P,                   1 },=1
{ MODE_TV,                  3 },=3
{ MODE_AV,                  2 },=2

{ MODE_NIGHT,               8 },=8
{ MODE_LANDSCAPE,           7 },=7
{ MODE_VIDEO_STD,         16  },=16
{ MODE_STITCH,           0xFF },=15
{ MODE_MY_COLORS,           4 },=4
{ MODE_SCN_NIGHT,          14 },=14
{ MODE_SCN_CHILD,        0xFF },= n.a.
{ MODE_SCN_PARTY,          13 },=13 Indoor
{ MODE_SCN_GRASS,           9 },=9 Foliage

a640, ixus 630, and ixus_izoom still have problems, see ewavrs post  http://chdk.setepontos.com/index.php/topic,3228.90.html

Also, in the newer cameras (ones that use numbers like AUTO= 32768, VIDEO_STD=25xx etc) the common modes like M, P, TV use exactly the same values, but the scene and video modes do not.

edit:
also a630, a700 have problems

In changeset 855 I've adjusted a630, a640, a700, ixus60, ixus65. These are not verified, but probably better than what was there before.

About http://tools.assembla.com/chdk/changeset/856 :
Indeed, for a710  MODE_SCN_COLOR_SWAP must be used instead of MODE_MY_COLORS.

I've updated a710, a630 and a640 in changeset 857. All of these appear to have "color swap" instead of "my colors"
