Yes, I agree with the latter.  What I menat is the following: after the 
data has been added to the array, the compiler should use the string 
length of the array, so if you do

CHARACTER*10 z
z = (/ something /)
print *, z

all printed strings should be length 10, no the contents of the constructor.

ok, thanks.
