The different types of data files used in QBasic are:
Sequential Access Data File:
Sequential Access Data File:
- The file that performs reading and writing operations sequentially or in an order from the beginning to the end of file is sequential access data file.
- In this data file records are written one after another and can be read in similar manner as they were written. In such sequential data file, reading and writing takes places sequentially.
Random Access Data File:
- The file that performs reading and writing operations randomly in any order is random access data file.
- In this data file any records are written and read directly without going through all previous records. Information in random access file is stored and accessed in separate numbered unit called "RECORDS"
