Re: [MacPerl] CGI scrolling_list

[Keary Suska <aksuska@insideflyer.com>]

You are getting the message as a function of the -w switch on the #! line.
Any non-quoted text is first interpreted as a command or subroutine. If none
match, it is considered a bareword and is typically resolved to string, but
recommended against as the word could be a future command. In your case, I
think the ambiguity comes from the '-' leading the string, as Perl isn't
sure whether you mean subtract or as part of the string. You should encase
the parameter names in quotes to remove any ambiguity.

The values parameter takes a reference to an array or list. Check the docs
for references and you will find your answer.
