How to selectively assign element output to different parts of a vector?

How do I link multiple scalar sources together into a single vector?

I have several stream gages, some with historical data, some that needs to be simulated. The data that I want to pass into the vector varies by gage.  

I have a set of array labels corresponding to the complete list of stream gages. I have a vector that uses those gages as Row Labels.

What is the function syntax to define what variable is connected to what element of the vector. In other programming languages it would look like:

Array Labels: Gage_1, Gage_2, Gage_3

Gage_1 uses observed data stored in ObsData[Gage_1]
Gage_2 uses observed data stored in ObsData[Gage_2]
Gage_3 uses simulated using a function Gage_3_Sim


Intuitively, I'd expect the equation to look like this, but this doesn't work.

[ObsData[Gage_1], ObsData[Gage_2], Gage_3_Sim]

I'm sure this is a simple syntax issue, but I couldn't find the answer easily.

Thanks!

    Solved! I was looking for the "Vector Constructor" function described here:

    vector(Array Label Set, Value1, Value2, …)

    Page,

    Thanks for writing in the forum! Yes that is the answer I would have provided as well. Note that you can also use a Data element with the Type set to the Array Label Set you are using. This probably isn't what you need for this particular problem, but in the future, if you have to reference a large set of outputs, then you can use =CONCATENATE() in Excel to quickly generate a list of outputs then copy and paste these names into the Data array table. In the example below, I am grabbing the outputs for all the reservoirs within a model and referencing their names of the outputs. For long lists of outputs, the concatenate function in Excel is helpful to quickly generate that list. Just put the list in 1 column then the concatenate function can be used to fill in the other parts of the names (i.e. ".Volume" in this case). I know this likely isn't what you need right now but in case your list is long, this could be used.
