note cees <p>Make sure you know what you are doing when adding & to the front of a function call. It can have unintended consequences if you do not understand the difference. Here is the relevant section from perlsub that briefly explains the difference:</p> <tt><pre> To call subroutines: NAME(LIST); # & is optional with parentheses. NAME LIST; # Parentheses optional if predeclared/imported. &NAME(LIST); # Circumvent prototypes. &NAME; # Makes current @_ visible to called subroutine. <pre></tt> 500367 500367
