GPIB read/writes

Highlighted
I am using a power supply with a GPIB interface and controlling it thru a
GPIB card, using Labview 5.0.

I am missing one thing and that is to read and write the data points from
the Power supply to a data file. I have tried several ways and none of them
work for me. I need to open a file, read the data approx. 1/sec and close
it thru a GPIB interface. I am reading several data points at one time,
and would like to open one file and have all the data points dump into that
one file when all the nested loops are finished.
Is there a way of buffering to store the datapoints and dump it into a file
when the nested loops are finished?
I am not sure where to go from here?
