a single element array slice is my @a=split(//,@_[1]);. @_[1] should be written $_[1]. This is spelled out when you use warnings or (-w).

Just putting use strict; (not Strict, leading upper case is generally used for modules, 'strict' is a pragma) at the top does not make your script run under 'use strict;'. The script you just posted will not even compile.

Please turn on warnings ('-w' on the shebang or 'use warnings;') and 'use strict;'. Then go through your code make it run without giving a warnings. If you have a problem, grab the section you are having a problem with and post the snippet here and ask for help.

I apoligize for not answering all of your questions outright, but you'll do much better in the long run if you go though these things yourself instead of me answering them for you. Hope you understand.

    • Update: also chipmunk posted some good code and one of the best things to do is take some good code like chipmunk's and go through it until you understand it. (I get to thank merlyn for letting me do that to his code :) )
