Variables Dereferencing Symbols

Perl uses three special dereferencing symbols to differentiate variable types

$	Scalar variables	Single value of any type
@	List variables	Array of scalar values - integer index
%	Associative array variables	Hash table of scalar values - string key

Conceptual Examples:

$name	"John"
@johnRecordA	Element 0 is "John" Element 1 is "Moreland"
%johnRecordB	Element "name" is "John" Element "age" is 34
