I tried posting this twice already with the complete thread intact. But
it would not post. Therefore, I have removed all of thread with
exception of most recent post that I am replying to.
Mike --
You've been a great help on this.
First:
|AB = CreateObject("Broker.Application");|
|ADoc = AB.ActiveDocument;|
|ADoc.Name = "SPY";|
does indeed make SPY the current ticker, assuming the previous ticker
contains some data already. For the time being I will (manually) insure
that the previous ticker does contain data, before starting the function
(via paramtrigger()).
When I first received your suggestion with the jscript example, I tried
this:
|AB = CreateObject("Broker.Application");|
|AB.ActiveDocument||.Name = "SPY";|
which produces a Syntax error with the cursor just before .Name. I
obviously do not understand the required structure, since the two
snippets of code are equivalent in my mind. Though they are obviously
not to the AFL checker.
Second:
In answer to your question:
"What would you expect the result to be if you had something like this:
_TRACE("Close is: " + Close);
<swap out symbol>
_TRACE("Close is: " + Close);"
I would expect that the first _Trace would display the close of the
previous symbol and the second one would display the new symbol.
My expectation was wrong! After the swap, the first close was displayed
3 more times (within the same 10msec period, from 3 separate _Trace
statements in the code). Then after 20msec, and two more 20msec
periods, the new close was displayed for a total of 3 times.
BTW, my intention is to use this ONLY when collecting symbols and prices
from a file for trading the following day (using paramtrigger()). It is
done only once a day. And is not done at all while trading.
Thanks again.

Kieth,
My example was for an external javascript (e.g. .js file).
Trying to change the active symbol from within a running AFL is
probably not a good idea (if at all possible) since you would
effectively be executing AFL code that would be cutting your feet out
from under yourself (i.e. running script over a symbol that changed
the symbol before the script was finished running).
What would you expect the result to be if you had something like this:
_TRACE("Close is: " + Close);
<swap out symbol>
_TRACE("Close is: " + Close);
I'm not sure exactly what scenario you are trying to capture. But,
what I was suggesting was to run an external javascript to drive
AmiBroker, not driving AmiBroker from within AmiBroker.
However, to answer your question; Your problem is that you are mixing
javascript and AFL incorrectly. You would just need to use AFL.
e.g.
AB = CreateObject(...);
Doc = AB.ActiveDocument;
Doc.Name = ...
