Nat,
Thank you for looking at this. the log you got is correct. I had a missing
statement (Missing S) in a program which was run earlier.
the missing statement is global in scope. so that is why my sample code was
OK. I failed to check the previous code and jump to conclusions.
I guess it is too late for me to stay on the L.
Again thank you.
Yu
