In PS A720 auto ISO values are set in 1/16 values not in 1/10 like menu says. So for ISO50 you should set 3 (not default 5), and for ISO 640 set 40 not 64 (and so on).

Good solution is to display/configure auto ISO values in pure ISO without multiplier (10 or 16).

The SX100 has two power buttons, one to boot into play/review mode, one to boot into record mode.

With chdk it always boots into review mode, no matter which button was pressed. Pressing the button too long prevents the camera from booting at all.

Topic was discussed here: ​http://chdk.setepontos.com/index.php/topic,1907.0.html

ewavr's modification from the end of the thread do kinda work, though it is necessary to hold the power button for at least one second, or the cam wont boot.

The get_next_token function has quite a high impact on the performance of micro basic. Adam Dunkels's original micro basic had only 13 keywords, so this function could afford to be inefficient. Micro basic currently has over 130 functions and could benefit from improvements in this function.

There are two obvious improvements:

1. pre-calculate the lengths of the keywords, rather than do it in the inner loop
2. use a binary search rather than a linear search to find the token (this requires the keywords array to be put in lexical order).
