That said, it doesn't help to chop the code up into too small pieces, which arguably the case for Assignment 1. Assignment 2 is another matter. As far as I can see, you really will need multiple files, which can be any combination you choose of Shell, Awk and Sed scripts (and more than one if it works better). You may recall me saying, in the context of the Sed lecture, that it's better to use a number of small scripts - and get them right - versus a very complicated omnibus script. Cheers MichaelW
