Subject: Is it possible to eliminate the temporary variable

Hi all,

I use the following script to read a file and create a 2D array.
What bothers me is that I have to use a temporary variable. I wonder if
there is a better way to read a file and create a 2D array.


Thanks,

Li


##################
# create a 2D array

def file_process
    @data=[ ]

   # read in the file line by line
   File.open(@file) do |a_file|
      temp=[]
      a_file.each_line do|a_line|
  a_line.chomp!# remove \n
  temp=a_line.split(/\t/) # tab is the separator
  @data << temp
  temp=[]
     end
   end
end
