Hi Stuart, Well, it does seem to work that way, but you should do the stringifying only as you print. Under most circumstances, you should not enclose variables in quotes. Single quotes prevent the variable name from being interpolated at all, and double quotes do string magic, for good or ill. The warning you got about concatenation should indicate something to you about what you are asking for when you double-quote a variable. Perl interprets the variable as a single string, then concatenates that string with the substrings preceding and following it. They may be empty strings, but Perl will attempt the concatenation anyway, and choke on any variable that is unitinaialized, and therefore not interprible as a string.
