Variables Basic Associative Array Functions

Perl provides several built-in associative array management functions to help with deal with their special considerations

%days = ( 'M', "Monday", 'T', "Tuesday" );

The keys() function returns a list of keys

@letters = keys( %days );
# Yields ( 'M', 'T' )

The values() function returns a list of values

@names = values( %days );
# Yields ( "Monday", "Tuesday" )

The delete() function removes a Key-Value pair

delete( $days{'M'} );
# Yields ( 'T', "Tuesday" )
