For each is supposed to work as follows.
1. Powerpro.exe calls your foreach callback.
2. Your plugin calls setvar on the foreach variable to overwrite its current
value with a the next result in the enumeration.
3. setvar calls changerefifhandle which calls your free function if the
variable being set already contains a handle (note: the old value of the for
each variable is what I mean, not the new value being set).
4. Your plugin returns from doforeach.
5. Processing in powerpro.exe now calls changerefifhandle on the foreach
variable, which will call back to your plugin to increment ref count.
I won't have time to track your script execution from powerpro.exe end until at
least late in the weekend . If you wanted to play with it before then, you
could insert traces in your plugin in the foreach, free, and ref increment
callbacks, and so see if they are called as expected. You could include the
scriptline number in the trace (getvar("scriptline")) to help relate the trace
to the executing script.
I don;t know how the ref count for the enumeration handle got set to two. I or
you would need to do some tracing to find out at what script line that is
happening.
