Adexl Results Data Access for a Custom Results Export Format

Hello:

I am trying to create a function that can be run with an adexl session that saves output data from a corner's run in a specific format.  The first step is to get the data from the results.  At the moment I am only interested in DC results but I may expand it later to include other results.  Since I am running it over corners it seems like I have to open the overall results directory to the list of corners and their results directory number and then open the results directory from each corner individually to get the actual data for that corner.  Is this necessary?  Is there a way to get the data in a waveform or object over corners directly?  Otherwise do I need to add a loop over the corners and open the result directory of each corner?

Another way of approaching this would be to save the data as a csv and then open the csv and convert it to my format.  Is there a SKILL function for running the "Save to CSV" function that you can run using the button to save the results table data in ADEXL?

Also, my function for getting the waveform from the expression obtained from the output object seems overly complicated.  Is there a simpler way to do this? I was able to simplify by using eval, but is there another function that handles referencing to other outputs, etc?  What do famEval and awvEval do?  When I use them on output->expression, they just give me back my input, a two element list with the access function and then the signal/net as the elements.  e.g.(VS ("/DIO4/V_DIO"))
