  Normally when you read from  stdin  kind of input where end of line  markers 
are used to   end the current input,  the new line markers  are not read in  to 
the field.  So  experiment  before you  begin "chomping: on it unnecessarily. 



  This can get expensive depending on the  size of the array.

  Hello Jim:



  I am certainly no expert, but in my experience, you should always use chomp 
when extracting the values of the elements of an array.  At any rate, it 
couldn't hurt, because it will remove only the new line character or \n at the 
end of the line, if any.

    Hi,

    Maybe I'm not understanding this. Here is some code.

    print "Enter some numbers on separate lines: ";

    my $user_total = total(<STDIN>);



    I'm pretending that there's a subroutine that adds up the numbers.



    I'm thinking that I would enter the numbers from the keyboard on separate 
lines, and when I'm done, I'd press the key combination that signals end of 
input.



    When the program gets the array, I'm thinking that each line would have a 
new line on the end of it.



    Here's where the question comes in.



    Would the subroutine need to use the chomp function to get rid of the new 
lines before it adds up the numbers, or would it be happy with the line endings?



    Thanks.



    Jim
