According to the reporter:

In the FREQUENCIES command  : centiles above 50 are calculated ONLY
if NTILES subcommand is written before PERCENTILES subcommand:


Command file #1 :

******************************************************************


DATA LIST NOTABLE FILE=exemple44 /X1 8 X2 10-11.
VARIABLE LABELS X1 "Sexe" X2 "Age".
