`my @a = ('A'..'Z');` Without the quotes A and Z are "bare words" that could be interpreted as something other than the manafest constant strings that you intended. Consider for example: `sub A { 'K'; } my @a = (A..'Z'); print join "\n", @a;` [download] Perl is Huffman encoded by design.	[reply] [d/l] [select]

Whenever you see a bareword error, it usually means that you have a string in your code that needs to be quoted. Put quotes around the two strings that your Perl interpreter identified as bare words and see if that doesn't make the problem go away.	[reply]

I might have just changed the double-quotes to single-quotes to avoid unnecessary interpolation of the vars... `my @a = ('A'..'Z');` [download] rather than `my @a = ("A".."Z");` [download] Update: I overlooked the post by GrandFather, which mentioned the single quotes. oops.	[reply] [d/l] [select]

This brings to mind merlyn's recent meditation: Why use strict is good, and barewords are bad -- Oh Lord, won’t you burn me a Knoppix CD ? My friends all rate Windows, I must disagree.
