It also doesn't say much about regular expressions, threading,
object-oriented programming or EBCDIC.
NAME
perlvar - Perl predefined variables
DESCRIPTION
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) { ... }
