Accessing local variables of a sequence from the sequence calling it

[TiWi]

Hi,
I am looking for a way of accessing the local variables (or even the entire context) of a sequence from the calling sequence. The called sequence is run in a new thread. In my test I call the same sequence many times and would like to keep most of the variables in this step to simplify maintenance since those variables will only be defined in one place. After running all those sequences, I will add a few test steps using the local variables of the previous sequences. I would like to have something like RunState.Sequence.Main.MySequence1.Locals.MyVar1, RunState.Sequence.Main.MySequence2.Locals.MyVar1, etc. to access the variables. Therefore in the future when I add new locals to my sequence I wont have to update a whole bunch of sequences. So is there a simple way to do that, or something close to it?

Thanks!

Louis

Louis -
Here is the general idea.
1) You could create a container, i.e. Locals.Thread1.Locals in the calling sequence.
2) In the setup group of the called sequence, you could use the ActiveX adapter to call SetPropertyObject("Thread1.Locals", PropOption_NotOwning, RunState.Locals) on the "RunState.Caller.Locals" object. This will change the Locals.Thread1.Locals property in the calling sequence from a container to an alias object that points to the called sequence's locals. Even when the thread completes, the Locals.Thread1.Locals variable will point to the old copy of the called sequences locals. Look at the PropertyObject.IsAliasObject help for some discussion on alias objects.

For the 1st option, if I understand correctly I will create an empty container in the calling sequence, pass it by ref to the called sequence and fill it up with the local variables. Is there a simple way to put all my local variables in this container?

Thanks!

Hi Louis,

Actually, the suggestion by Scott is not two different options but a two step process. This will create a container that references your local variables. Therefore you need to go through both steps.

Actually I've created a container with the data I wanted my sequence to get and passed it by reference to my subsequences. Then I store the data in the container which is automatically available to the calling sequence. I would have prefered not to pass data like this but it was simple enough...

Could you put together a simple example.  I am trying to do the exact same thing
