ks statistic 3 samples

[kcodo]

PROC NPAR1WAY data=mydata wilcoxon; 
Class group;
             Var gaitspeed angle;
label group='0'='control'
'1'='OA' '2'='LSS' ;
run; quit;

when i run this code

the output gives KS=0.37 Ksa=2.04

but there is no p-value given. 

how do I get the p-value?

how do I interpret the KS where class=3 levels as indicated by label 0 (control), 1(OA), 2(LSS)?
