#8 CobolBuilder writing records to single line

[Anonymous]

Hi,

I am using jrecord to write records to file. But i writer is writing all records to a single. Can you please
check if below code is correct.

    final ICobolIOBuilder ioBuilder = JRecordInterface1.COBOL.newIOBuilder(
        "copybook").setFont("CP1252"); 
     AbstractLineWriter writer =  ioBuilder.newWriter("output.txt");
     AbstractLine outline = null;
     while(resultSet.next()){
       outline = ioBuilder.newLine();
       outline.getField("id").set(resultSet.getInt("id")));

       writer.write(outline);
       }
       writer.close();


  Excpected  Output:
  1234
  5677

  Receiving o/p:
  12345677

  Can you please update how i write individual record into multiple lines

  Thanks
  babu

What you need to do is set the setFileOrganization(Constants.IO_BIN_TEXT):

final ICobolIOBuilder ioBuilder = JRecordInterface1.COBOL
            .newIOBuilder("copybook")
                    .setFileOrganization(Constants.IO_BIN_TEXT)
                    .setFont("CP1252");

Thank you!Bruce .It is working perfectly now. Can you update how Constants.Io_BIN_TEXT helped here?

JRecord is designed to work with Cobol data structures. The setFileOrganization
tells JRecords are to be organised - i.e. what the line seperator is.

Fixed width Records

With length records, each record is a fixed length. There is no /r / n etc between individual records.

<--Record 1 --><--Record 2 --><--Record 3 -->

This is what was being used initially. JRecord provides 2 versions of fixed length records

          .setFileOrganization(Constants.IO_FIXED_LENGTH_RECORDS)

does byte (stream based IO). You can use it for single byte charactersets / binary files.

          .setFileOrganization(Constants.IO_FIXED_LENGTH_CHAR)

Used for multi-byte character-sets (e.g.UTF-8, UTF-16)

VB Records

With Variable length records you have

   <record-length><--- record data  --->
   <record-length><---   record data     --->
   <record-length><--- record data --->
   <record-length><---        record data       --->

JRecord provides several VB formats Constants.IO_VB, Constants.IO_VB_DUMP, Constants.IO_VB_FUJITSU, Constants.IO_VB_GNU_COBOL

Text files

For standard text files you can use

         .setFileOrganization(Constants.IO_BIN_TEXT)

or

         .setFileOrganization(Constants.IO_UNICODE_TEXT)

With Constants.IO_BIN_TEXT all IO is done at byte (stream level).

With Constants.IO_UNICODE_TEXT standard Java Read / writers are used

Thank you! Bruce for the detailed explanation.
