Create the following diagram to programmatically open, write to, and close a text file.
Customize the gray sections for your unique programming goals.
|Open, create, or replace a file by using the Open/Create/Replace File node and specifying its precise behavior. To access the enumerated list of possible behaviors, create a constant from the operation input of the node.|
|After the file opens, a unique identifier called a refnum represents the file. A file refnum is required for most nodes that process files.|
|Process the file by using a file I/O node from the File I/O palette category. You can interact with binary or text files. In this example, Write to Text File writes Hello world to the file represented by the file refnum.|
|Close the file to release the object from memory and avoid potential errors. If you do not close a file, LabVIEW cannot close the reference until the VI that opened the file finishes executing.|
