OpenSTAAD Items/Orders of Array From Output

Currently i am developing macro to output stresses and moments from plate elements.

I am referring to OpenSTAAD_Reference_V8i(4).pdf, and using Staad Pro (SELECT series 6)

I can't find OpenSTAAD reference for series 6. Is there any?

In the reference for series 4, output array order/items are not clear. Is there any guidance that i can follow? If there is, I would appreciate you telling me where i can get it.

For example, i am using Output.GetAllPlateCenterStressesAndMoments, and i can successfully get CenterStressesArray, which is an eight dimensional array that returns plate center stresses and moments.

But, there is no way to know which value indicates, for example, SLX, SLY, SLXY, MLX, MLY, MLXY, QLX, QLY.

Help in the application shows the below, where the exactly same explanation with the reference as the above is found. 

We appreciate your help regarding the above.
