   hi   
   	   
   Sometimes the answer is right in front of you and you can not see it!!!!.   
   Thank you for your reply ... I have solved the task by reading the text   
   file and then line by line store the line to variables and then insert   
   them in the application.   
   my email is juul@larsen.dk   
      
   kind regards pjl
