Response spectrum analysis - acc file information.

The option of saving the accelerations file used in the response spectrum command will generate a file with the extension ".acc" listing the accelerations of all the joints in the structure. 

Question:  Is the information provided in the ".acc" file accessible via Open.Staad? If yes, what functions are used to retrive this information? I'm aware of the posibility of creating my own VB routine that would actualy read the ".acc" file. I'm trying to see if there's a way via Open.STAAD.

Thank you.
