Using CMI.suspend_data with multiple variables

[Matelot]

I have three user-defined variables that I am passing to the LMS via CMI.suspend_data. A stored procedure within the LMS needs the data from each variable to be passed in a specific order.

Does anyone know if there is a way to ensure each variable's content is appended to CMI.suspend_data in a specific order?

Alternatively, can anyone point out where I need to look under the bonnet, to see when and how published content (SCORM 2004) is passing these variables to the LMS?

I have learned that the best way is to parse the data based on variable name bcause then the order does not matter. That is not always easy.
Through trial and error I was able to determine that the sequence in which the variables appear seems to depend on when they were last used. To solve this problem what I did was to have a series of actions just before the person exited to use them in the order I wanted them to appear. Sorry, I do not remember whether first appears first or last. Anyway, since I could not be sure when they would exit, I put all the actions in a group and ran them with a title level action On Show for every page. Did not slow anything down. They looked like this:
On Show, Modify Variable, Target: Variable1; Value: Var(Variable1)
On Show. Modify Variable, Target: pageUsage; Value: Var(pageUsage)
etc.
