It also doesn't say much about regular expressions, threading, 
object-oriented programming or EBCDIC.

       perlvar - Perl predefined variables

       Predefined Names

       The following names have special meaning to Perl.

Ya got the wrong man page.  I think you want perldata or perlintro.

           You might be tempted to use "$#array + 1" to tell you how many
           items there are in an array.  Don't bother.  As it happens, using
           @array where Perl expects to find a scalar value ("in scalar con-
           text") will give you the number of elements in the array:

               if (@animals < 5) { ... }
