Subject: improperly exiting loop with DATA and __END__

Content-Type: text/plain; charset=us-ascii

I have this bit of code that loops through the __END__ data and does some time sheet processing. All that bit works, but when I get to the end of the "DATA"  I get an error about calling split for a nil:NilClass...I an sure it is because I am trying to process the last record which is an empty  string.  I've been googling and looking at the book for hours, but can not get this bit right. How do I  trap the empty string and exit the loop  properly. Thanks in advance for any help!



 Friday -- Morning hours 4.75  Afternoon  5.23   total  9.98

hour_calu.rb:12: private method `split' called for nil:NilClass 

(NoMethodError)

 >Exit code: 1 


>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

while times = DATA.gets.chomp.split(",")

      day_of_week = times[0].split(",")

    ##bunch of other rubish calculations go here

    printf(" %8s -- Morning hours %01.2f  day_of_week, morning_e_time)
     week_total =+ morning_e_time + afternoon_e_time
end


puts
##printf("Weekly total %01.2f\n",week_total)
