How to export data using comsol 3.5a scripting

Hello,

I guess pretty much everything is in the title:
I'm using comsol 3.5a to simulate diffusion profiles. In order to work on the results of the simulation, I need to export the data. In GUI mode I use "File/Export/Postprocessing Data.../Stored output times on a subdomain using a regular grid".

Does anyone know what the command line for this instruction is? I cannot find it in the manual or any forum...

Thanks for helping!
