None: Replaces only the first occurrence within the specified range.           G: Replaces all occurrences within the specified range.           C: Request user confirmation before replacing. E: Ignore errors in the execution process.
Note: All flags above can be grouped together, for example, the GC represents a replacement for all occurrences within the specified range, and the user is asked to confirm each time it is replaced.
