Data Transfer I/O Statements

Input/Output (I/O) statements can be used for data transfer, file connection, file inquiry, and file positioning.

This section discusses data transfer and contains information on the following topics:

  • An overview of records and files

  • Components of data transfer statements

  • Data transfer input statements:

    • READ

      Data can be input from external sequential or direct-access records, or from internal records.

    • ACCEPT

      This statement is the same as a formatted, sequential READ statement, except that an ACCEPT statement must never be connected to user-specified I/O units.

  • Data transfer output statements:

    • WRITE

      Data can be output to external sequential or direct-access records, or to internal records.

    • PRINT and TYPE

      The PRINT statement is the same as a formatted, sequential WRITE statement, except that the PRINT statement must never transfer data to user-specified I/O units.

      TYPE is a synonym for PRINT. All forms and rules for the PRINT statement also apply to the TYPE statement.

    • REWRITE

      It rewrites the current record and it can be formatted or unformatted.

File connection, file inquiry, and file positioning I/O statements are discussed in File Operation I O Statements.
