     this is a problem I noticed sometime ago.
The problem (as I found) was that the READE function doesn't work the same
as the equivalent RPG READE op-code. If you look at the target job on the
as/400, you will find that the job is still reading the file looking for
matches ! It never seems to end ...

At this point I gave up with PBD & used the std as/400 classes and wrote a
simple procedure to check if I had got a match.

The following code is a bit messy but hopefully gives you the idea.
The ORDHDRK (format ORDHDR) file is keyed by Company then Order No.
The READE on ORDDTLK file first does a position to & then does a
READE but with no actual key. We then invoke the CheckORDDTLKkey
function to decide if there was a match !

  Object[] key;
  Object[] nokey = new Object[] { };

      BigDecimal TotODQTYO = new BigDecimal(0.0);
      BigDecimal TotODLVAL = new BigDecimal(0.0);

      // Read a ORDHDR using the key array.
      key = new Object[] {"01",new java.math.BigDecimal(725075) };
// read is effectively a CHAIN op-code
      if ( (ORDHDR = ORDHDRKfile.read(key)) != null )
      {
        // Retrieve field values from the ORDDTL.

        ORDDTLKfile.positionCursorBefore(key);
        int eof = 0;
        while ( eof == 0 ) {
          if ((ORDDTL = ORDDTLKfile.readNextEqual(nokey)) != null) {

            if (( eof = CheckORDDTLKkey(key)) == 0) {
              TotODQTYO = TotODQTYO.add(new BigDecimal(new
String(ORDDTL.getField("ODQTYO").toString())));
              TotODLVAL = TotODLVAL.add(new BigDecimal(new
String(ORDDTL.getField("ODLVAL").toString())));
            }
          }
          else { eof = 1; }
        }
      }


// Heres the checking of the keys

  public int CheckORDDTLKkey(Object[] Keylist) {

      for (int i = 0 ; i<Keylist.length ; i++) {
        String keystring = new String(Keylist[i].toString());
        try {
          String filekeystring = new
String(ORDDTL.getField(ORDDTLKrecformat[0].getKeyFieldDescription(i).getFieldName().toString()).toString());
          if (! keystring.equals(filekeystring)) { return (1); }
        }
        catch (Exception e) {
          System.err.println("Exception error: " + e);
          this.statusBar.setText(e.toString());
          e.printStackTrace();
          return(1);
        }
      }
      return(0);
    }
