LST.Reverse

Reverse the order of elements in a list.

 

 

Intention

 

The LST.Reverse command reverses the order of elements in a list container.

This is useful when you need to process the list elements in reverse order.

 

The elements will be reversed in the list.
The original list handle will still be valid and all elements will be in the list as before but in reverse order.

 

 

 

Illustration

 

Before LST.Reverse operation:

 

List: [1, 2, 3]

 

After LST.Reverse operation:

 

List: [3, 2, 1]

 

The elements are reversed in the list.

 

 

 

Syntax

 

 

LST.Reverse|P1

 

 

Parameter Explanation

 

P1 - (Variable)

 The handle of the list to reverse.
