The character '>' appeared at the first column of my original 
message was automatically converted to '|' somehow (I don't know
why). I list the Miranda code here again (leave first coulmn
blank):

 > ns    = map numval (lines (read "data"))

 > n     = # ns

 > sqrts = map sqrt ns

 > sum_sqrts = sum sqrts

 > avg_sqrts = sum_sqrts / n

 > men_sqrts = sum (map minus_avg_sqr sqrts) / n
 >             where
 >             minus_avg_sqr x = (x - avg_sqrts) * (x - avg_sqrts)

 > result  = "number of values = " ++ show n ++ "\n"
 >           ++ "sum_sqrts = " ++ show sum_sqrts ++ "\n"
 >           ++ "avg_sqrts = " ++ show avg_sqrts ++ "\n"
 >           ++ "men_sqrts = " ++ show men_sqrts ++ "\n"

 > main    = [Stdout result]

Sorry about this.

Liu.
