LST.QuePush

Add a Value to the End of the Queue

 

 

Intention

 

The LST.QuePush command is used to add a value to the end of a queue in a specified list container. This is useful for managing data in a First-In-First-Out (FIFO) manner, where the first value added to the queue is the first one to be retrieved.

The queue is a fundamental data structure that allows you to store and retrieve values in a specific order. The LST.QuePush command adds a value to the end of the queue, while the LST.QuePop command retrieves and removes the value from the front of the queue.

 

 

Syntax

 

LST.QuePush|P1|P2

 

 

Parameter Explanation

 

P1 - The handle of the list container. This is a numeric value or a variable that contains the handle of the list.

P2 - The value to be added to the end of the queue. This can be a numeric value, a string, or a variable containing the value.
