I thought I could do below but does not work. does split( )[ ] illegal pattern as below? I thought I could pass two argument to below sub. First argument is something like 1:3:33:2:33:5 and wanted to only store 2nd and 3rd into the array and push the second argument into it and join them by - and return the variable. Did I make program or syntax mistake or is this just not possible using below? 
     73 sub extract {
     74    $_ = shift;
     75    my @extract_i = split(/:/)[1,2];
     76    push @extract_i, $_[1];
     77    my $i_pstn = join('-', @extract_i);
     78 }
