My solution would be something like this...
Although, I'm not sure I like that the ouput is
sent to stderr. I like to preserve that for errors :)
#!/usr/bin/perl
use strict;
my $language = Select('Select your language:', qw(English Francais));
if($language eq 'English') {
print "Thank you!\n";
}
elsif($language eq 'Francais') {
print "Merci!\n";
}
else {
print "Unknown language: $language";
}
sub Select
{
my($prompt, @choices) = @_;
while(1) {
my $i = 0;
print STDERR $prompt, "\n";
print STDERR join("\n", map{++$i.") $_"} @choices), "\n";
my $answer = lc <STDIN>;
chomp $answer;
if($answer =~ /^\d+$/) {
return $choices[$answer-1]
if defined $choices[$answer-1];
} else {
my $out = [grep {lc $_ eq $answer} @choices]->[0];
return $out if $out;
}
}
}

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
