No, it doesn't. Eu reports the length of screen, (again, copied and 
pasted from your e-mail, as 7.    That's correct, there are seven 
elements,  
1.Customer No, 
2.Name,  
3.Addr1,  
4.Addr2, 
5.City, 
6.State, 
7.(y/n)

If you ask the length of screen[1], you'll get 12, and the length of 
screen[7] is 3.
