awk ignores fields with only spaces or empty


Does any one know how to avoid the scenario where awk ignores the fields having only spaces or empty fields?

for instance,

Data: "a","b","c","d","","   "

awk -F, '{ print NF }' File

the output I get is 4 instead of 6 do you know how to avoid this?

# awk -F, '{ print NF }' file

Its working for me in AIX v6

$ echo '"a","b","c","d","","   "' | awk -F, '{ print NF }'

Which version are you using?

Could find number of fields differently

cat file | tr "," "\n" | wc -l

Sorry - I realized later that the empty fields are just nulls.
