File Reading & Writing

[CCDAKE]

I am pulling information from data entry screens and attempting to save them 
to a file.   The File Open (ReadWrite mode),  File Write, and File close 
appears to be working correctly (returning a file handle and error code ptr 
is returning NULL).   I then open the file (Read only mode) and read, but the 
no# of objects returned is 0 and my buffer is empty.   I enclosed the code - 
another set of more experienced eyes would be greatly appreciated:
******************************************************************************
***************
  FileHand fh;
  DWord openMode;
  SWord sResult;
  Long myRtn; 
  VoidPtr bufP;
 
  Err *errP =0;
  CharPtr pData;

  fh = FileOpen (0, "newfile", sysFileTFileStream, 0, openMode, errP);
  if (fh == NULL) 
  { 
    PalmMessageBox (DebugAlertAlert, "Error creating file");
    return;
  }     

  myRtn = FileWrite(fh, "Test Data String" , 16, 1, errP);
  if (errP != NULL) 
  {
         PalmMessageBox(DebugAlertAlert, "Error writing to file");
         return;
  }
    
  FileClose(fh);

      
//
// Debug Purposes:  Open file and read record to see if file was created
//                  correctly.
//
  openMode = fileModeReadOnly;

  if ((fh = FileOpen (0, "newfile", sysFileTFileStream, 0, openMode, errP)) 
== NULL) 
  { 
      PalmMessageBox (DebugAlertAlert, "Error opening file for ReadOnly");
      return;
  }     

  
  myRtn = FileRead(fh, &bufP,16,1, errP);

  SetFieldText(fldID, bufP, 17, false);
 
  FileClose(fh);
