OPEN STATEMENT:
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. If it is an input file, only the reading is possible, while in the case of an output file, only writing is possible. The file once opened remains open until it is closed by the CLOSE statement. The OPEN statement in its easiest form is as shown below:
