In that case, you can use this (I follow the convention that numbering of  
lines
and of entries starts with 0, but you can subtract 1 in the brackets, if  you
prefer starting at 1 in the function call):
 
-------------------------------
class String
def  extract_entry(which_line,which_entry)
data_array=IO.readlines(self)  # reads content of file into an Array ( each  
entry = one line)
line=data_array[which_line].split(",")
return line[which_entry]
end
end
 
file_name="data_to_split.txt"
res=file_name.extract_entry(0,1)
p  'result is'
p res

----------------------------
Best regards,
