LST.PopFirst

Remove and retrieve the first value from the List.

 

 

Intention

 

The LST.PopFirst command removes the first value from the List and stores it in a variable. This is useful when you need to process items in a FIFO (First-In-First-Out) manner.

The List is modified, and the first item is permanently removed.

 

 

Syntax

 

 

LST.PopFirst|P1|P2

 

 

Parameter Explanation

 

P1 - (Variable)

 The handle of the List to pop from.

P2 - (Variable)

 The variable to store the popped value.
