...put it in a variable?

Why does it need to be put in a variable? It appears that none of the first three implementations actually do that. --TimToady 00:14, 24 July 2011 (UTC)

I know what you mean. If we are going to read a line within a program, we need to be able to store what we have read in order to make use of it. A variable would usually be a good place. I have added "or in memory (for potential future use within the program if the code were to become embedded) ". I'm not sure whether we need the bit in brackets, and I am open to suggestions on other possible wording, if you think we need something else. Markhobley 00:45, 24 July 2011 (UTC)

FWIW The Tcl solution looks like it is using a variable named "line", which is an acceptable solution for the purpose of this task. I cannot read the other two languages, so I can't comment on the solutions. Markhobley 00:59, 24 July 2011 (UTC)

Looking again, I guess that the Perl6 solution is missing some file opening code, and closing code and is capturing to standard output. It probably just requires a small change. I have not got round to looking at Perl6 yet, so I am not skilled enough to make such changes at this time.Markhobley 01:06, 24 July 2011 (UTC)
