If &File2.IsOpen Then
   &TextPRINT = "Program  ABCEF";
   &File2.WriteLine(&TextPRINT);
End-If;
&File2.Close();

/***Opening File2 in Read mode ***/
&File2 = GetFile(&FILENAME2, "R", %FilePath_Absolute);
/***Check whether File1 Exists***/
If FileExists(&FILENAME1, %FilePath_Absolute) Then        
   &File1 = GetFile(&FILENAME1, "A", %FilePath_Absolute);
   /***read the data from File2 and  writing into File1***/
   If &File1.IsOpen Then
      While &File2.ReadLine(&Lin) 
         &File1.WriteLine(&Lin);
