LIST Function

Creates a list array.

result = LIST(expr₁ , ... expr_n)

expr_i One or more expressions or variables.

result A variable of type list.

None.

A list is an array of expressions or variables. Each element in a list can have a unique data type and value. The elements in a list can be accessed with subscripts, in much the same way that elements of an array are accessed.

The elements of a list can be any of the eight basic PV-WAVE data types, or other structures or arrays of structures, and other lists or associative arrays. Lists can also be used as structure fields.

This example creates a simple list with four elements: a byte value, a floating-point value, a string, and a structure. Both INFO and PRINT are used to show the contents and structure of the list.

lst = LIST(1B, 2.2, '3.3', {,a:1, b:lindgen(2)})

; Create the list.

INFO, lst, /Full

; Display information about the list.

LST	 LIST 	= List(4)
   BYTE 	= 	1
   FLOAT 	= 		2.20000
   STRING 	= 	'3.3'
   STRUCT = ** Structure $1, 2 tags, 24 length:
        A INT 		1
        B LONG 		Array(2)
PRINT, lst

; Print the value of the list.

{   1      2.20000 3.3{       1           0           1}}
