LST.FileRestore

Restore the Container from a File

 

 

Intention

 

The LST.FileRestore command is used to restore the contents of a list container from a file. This is useful when you need to reconstruct a list that was previously saved to a file using the LST.FileStore command.

The file contains a serialized string that represents the list's data and structure, allowing it to be fully restored to its original state.

 

 

Syntax

 

LST.FileRestore|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 file path to restore the list from. This can be a string or a variable containing the file path.

 

 

Example
