In SDM, there are various scripted and non-scripted bracketing functions.
For Tv override, the variable 'conf.tv_bracket_value' holds the number of 1/3EV steps each exposure will change by.
If that value is non-zero, it means Tv bracketing is enabled.
In function 'script_end()', I reset that value to zero.
A user reported that Example_6.bas provided with the download did not change exposures.
This uses the custom timer to capture a number of images.
If I comment-out resetting 'conf.tv_bracket_value' to zero in script_end() then it works fine.
It would seem that script_end() is somehow called immediately the script starts !
A quick look at the end of 'process_script()' in \core\kbd.c shows 'script_end()' is the 'default' in the switch statement and is also called on error or when all tokens are processed.
Offhand, I cannot explain the behaviour I am seeing.
Any ideas ?
