Ya, That was a mistake,  I was in a rush and keyed the wrong opcode.  
It should have been the CHECK opcode not the SCAN.   Sorry...  I guess 
from the other posts though,  that I'm not the only one who from time to 
time has hit the send key too early, and said "Ahhh   #$%@^*"

P.S. I guess the only thing worse would have been posting an example with 
an ITER statement that produced an Infinite Loop <G> <BG> <VBG> <LOL> <DOW>
