- OUTPUT mode erases all previous data in an existing file or clears a port receive buffer.
- Creates an empty file if the filename does not exist. Use APPEND if previous file data is to be preserved.
- Mode can use PRINT (file statement), WRITE (file statement) or PRINT USING (file statement) to output file data.
Writes new data to a text file sequentially and reads it back to the program screen.
