Writing to Files

  • Last UpdatedAug 18, 2026

When you open a file for writing, the file will be created if it does not already exist.

If you use Open('WRITE') and the file already exists, you will be shown an alert asking whether the file can be overwritten. Alternatively you may specify OVERWRITE, to force overwriting of a file if it already exists or APPEND if you want to add to the end of a file if it already exists.
