Get data from callback without global variable?

Hi,

I want to continuously acquire data in the background using the Data Acquisition Toolbox as described here. I have a callback function that is called when data is available. This callback can be used to log/process the data.

What is the most elegant/efficient way to make the acquired data available to other functions? Basically, at any point while the acquisition is running in the background, I want to be able to execute commands from the command line such that these commands have access to the data that has just been acquired.

One solution I can think of is to have a global variable in the 'DataAvailable' callback, which I can then access from other functions, but I'm not sure if that's the best solution.

Thanks!

Any ideas? Are globals the way to go here?
