i am trying to convert a file from ascii to ebcdic.  the conversion process works fine, but the resulting file is all on one line.

Any help would be most appreciated:

import java.io.*;

class eToATranslator
{
     public static void main (String args[])
     {
          try
          {
               //create and input stream reader                    
               FileInputStream inputStream = new FileInputStream ("XFERCED.TXT");
               //convert from ascii to unicode
               InputStreamReader inputReader = new InputStreamReader(inputStream,"Cp500");
               //attach a buffer to it
               BufferedReader buffReader = new BufferedReader (inputReader);

               //output file in ebcdic from unicode
               OutputStreamWriter outWriter = new OutputStreamWriter(new FileOutputStream("OutputXFER2.txt"),"Cp1252");
         
               String str = null;
               while ((str = buffReader.readLine()) !=null)
               {
                    outWriter.write(str+"\n");
               }
                         
               inputReader.close();
               inputStream.close();
               outWriter.close();
          }
          catch (Exception e)
          {
               System.out.println("Exception: " + e);
          }
     }
}

2 suggestions:
1. use outWriter.write(str+"\r\n") instead of outWriter.write(str+"\n")
2. Use PrintWriter:
//output file in ebcdic from unicode
OutputStreamWriter outWriter = new OutputStreamWriter(new FileOutputStream("OutputXFER2.txt"),"Cp1252");
PrintWriter printWriter = new PrintWriter(outWriter);
...
printWriter.println(str+"\n");
...

Thanks for the help.

The outWriter.write(str+"\r\n") almost works. Each line of the EBCDIC code now appears on a new line.

The problem is that each line now starts with a  character and the hex values of the end of line / new line are always the sequence 0D 0A 15

to the best of my knowledge:

0D is the EBCDIC and ASCII carriage return
0A is the ASCII line feed
15 is the EBCDIC new line

So, is the 0A in that sequence anything to worry about when this file is being processed by an ebcdic reading system? (so far i've only looked at it using UltraEdit 9)

Have you tried this?

outWriter.write(str);
outWriter.write(0x0D);
outWriter.write(0x15);

Even if it looks wrong in notepad, it may be valid anyway.

----------------------------------------------------
BTW - No big deal, but you are closing the same stream twice:

inputReader.close();
inputStream.close();
