Whenever a READ or a WRITE operation is executed on a file, then it should be open. The opening of a file may be completed with the help of the OPEN verb. With the OPEN verb it should be also indicated whether the file must be opened as an input file or output file.

The OPEN statement in its easiest form is as shown below:
