Printing all DC operating points of all devices

Hi,

I am a beginner in ocean. I have the following ocean script which reports the source current of transistor M3.

;*****************************

openResults("~/simulation/TEST_OPAMP_POLY_TB/spectre/schematic/psf/")
p=outfile("/home/mt2775_loc/simulation/TEST_OPAMP_POLY_TB/spectre/schematic/netlist/resultsSpectre.txt" "w")

fprintf(p, "Hello World! to make sure it is working\n" )
selectResult('dcOp)

fprintf(p,"%f",i("/I0/M3/S"))

;*****************************

I also know if I use outputs() command, all DC values will be printed out. 

The question is that which command can print all DC values into the file (instead of calling function "fprintf" for each one by one like above)? In short, I need a such command fprintf(p,"%f", outputs()). 

If I need to use a loop would you please let me how to write it.

Thank for your help
