# @arrayname = ("element1", "element2");
# an array can have as many elements as it wants

@browser=("NS", "IE", "NaviBrowse", "Goupa");

# USING AN ARRAY
# Let's try to grab IE from the array above

$browser[1];

# We get values from the array by assigning a variable with the same name as the array and
# the number of the value we want in the array.  in the definition of the example array,
# we have 4 values; each value has a number starting with 0.  So the numbers for the ex
# array are 0-3
# NS IE NaviBrowse Goupa
# 0 1     2    3
#
# You can change and add elements to arrays.  Here's how:

@browser=("NS", "IE", "NaviBrowse", "Goupa");
$browser[2]="Mosaic";

# "NaviBrowse" (third element) has been changed to "Mosaic"
#
# You can add elements to the last position of the array like this:

@browser=("NS", "IE", "Mosaic", "Goupa");
$browser[4]="NaviBrowse";

#To delete an element from an array:

@browser=("NS", "IE", "Mosaic", "Goupa");
splice(@browser, 1, 1);

# This uses the SPLICE function. See functions.pl for syntax
# The first element starting at position 1 has been deleted, so the array would be:

@browser=("NS", "Mosaic", "Goupa");

# You can replace elements in an array also with the SPLICE function like this:

@browser = ("NS", "IE", "Opera");
splice(@browser, 1, 2, "NeoPlanet", "Mosaic");

# This replaces "IE" and "Opera" with "NeoPlanet" and "Mosaic"

print @browser;
