[ map ]
The [map] method is used to cast an object to the map type.
This method may be used without parameters to create an empty map object. Alternatively the method accepts a list of comma-separated key/value pairs in the format key = value to populate the map at creation.
The keys and values may be of any type.

To create a map from integers to days of the week:
Use the [map] method with name/value pairs for each of the names of the days of the week as parameters. The following example stores a map which maps integers to the names of the days of the week in a variable named DaysOfTheWeek.
Code
var( DaysofTheWeek = map(0='Sunday', 1='Monday', 2='Tuesday', 3='Wednesday', 4='Thursday', 5='Friday', 6='Saturday') )
$DaysOfTheWeekResult
map(0 = Sunday, 1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday)

Be aware that maps are not stored in any sort of predictable order. If the order is important, use an array instead.
