Writing large csv data records to SD card

[bm_engineering]

I need to log to SD as many as 256 values (96 will be more common) to each csv record, fairly infrequently. Each value could be 6 or 7 characters, plus date and time. In earlier versions of this application we only had 20-30 values and I used the create CSV and write CSV function blocks which worked well. However, with the larger amount of data now, defining the create CSV function block for that many MI's is a lot of work (which I might need to do), and it seems like a data table doesn't allow enough columns for that big a record. Does anyone have any other suggestions?
