in reply to Get chatbox lines

there's no need to use splice in a void context to trim the cache in your getnewlines sub. just use the following code: 
my $CACHE_LIMIT = 50;

$#$cache = $CACHE_LIMIT - (1 - $[);

    The problem with this (now that I have tested it well) is that it enlarges the array when it is originally smaller than the limit. splice doesn't do that. Any ideas? Thanks,

      not besides just appending 'if @$cache > $CACHE_LIMIT';
