Hi Frank,

To simplify the task of running pairwise Mann-Whitney's U tests, you
can use the following macro:

Also, instead of Bonferroni (too conservative), you can select other
methods of adjusting the p-values (more sensitive), while controlling
the experimentwise alpha level:

As a matter of fact, if you had SPSS 12 (or newer), you could use OMS
to extract the p-values and combine both macros into one. But you tell
you have SPSS 10.1.
