LST.StkPush

Push a Value onto the Stack

 

 

Intention

 

The LST.StkPush command is used to push a value onto the stack of a specified list container. This is useful for managing data in a Last-In-First-Out (LIFO) manner, where the last value pushed onto the stack is the first one to be retrieved.

The stack is a fundamental data structure that allows you to store and retrieve values in a specific order. The LST.StkPush command adds a value to the top of the stack, while the LST.StkPop command retrieves and removes the top value from the stack.

 

 

Syntax

 

LST.StkPush|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 pushed onto the stack. This can be a numeric value, a string, or a variable containing the value.

 

 

Example
