A hash is a set of relationships, for example

Item Cost

Beans 300
Carrot 200
Apple 250


etc

To create this relationship in perl, use the hash notation

%vegetable_costs = (Beans => 300
Carrots => 200,
Apple => 250 );

To refer to the hash, you use $vegetable_costs{Beans} for the cost of beans etc

for eaxample, your program might have a print statement like

print "The cost of beans is $vegetable_costs{Beans}n";


If you understand that, try putting the words "perl hash" into Google.
