Defining files using record I/O

You define files for record-oriented data transmission by using a file declaration with the following attributes:

  declare
    Filename file record
             input | output | update
             sequential
             buffered | unbuffered
             environment(options);

The file attributes are described in the PL/I Language Reference.
