Variables Dereferencing Symbols

 

• Perl uses three special dereferencing symbols to differentiate variable types

  $	Scalar variables	Single value of any type
  @	Array 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
