Uenal,
I understand the functionality of Table Export/Import, but for
example in running an AA back test or optimization across multiple
symbols my understanding is that AB clears the contents of virtually
everything between one symbol and the next and it would be usefull to
be able to some how have persistancy in tables as opposed to having
to export them at the end of processing for one sysmbol and then
importing them again at the beginning of processing of the next
symbol.
On another topic, I know this can be done externally using OLE
Automation etc., but it would be usefull to be able to get at all
the "settings" information that AA has, a lot of which can not be
gotten with a STATUS("xxx") type command from within an AA.
