ARRAY

A = ARRAY [s | expr]

Creates a ARRAY or MAP variable from the given string s or expression expr. The ARRAY command supports JSON (Javascript object notation) syntax. The MAP provides value-key pair access along with array or dotted notation.

See STR for converting a MAP variable into a JSON string.

Example 1: JSON string to MAP

a = array("{Name: Alice, Age: 20}") print a print a.Name + " is " + a.Age + " years old" ' Output: ' {"Age":20,"Name":"Alice"} ' Alice is 20 years old 

Example 2: JSON with nested MAP

a = Array("{x:1, y:3, down:{x:4, y:7}}") print a ' Output: {"down":{"y":7,"x":4},"x":1,"y":3} 

Example 3: Array string to array

a = Array("[1,2,3]") print a ' Output: [1,2,3]
