ViScanf invalid format string due to #sample size data1, data2,... response

I'm writing a program which will utilize the internal memeory of the Agilent 34410A DMM for making fast measurements (10K/s).  In order to do this, I need to setup a test, have the data stored to the internal memory, then read and delete it, while other measurements are still happening.  The best command for the read/delete function is the R? command, but it returns the data in a strange format which breaks the ViScanf format string.  

an example of the R? reading in below:

R? 2

#231+2.87536000E-04,+3.18131400E-03

Is there a way to setup the ViScanf format string to handle this?

Thanks
