distribution - Specify alpha for KOLMOGOROV-SMIRNOV TEST in SAS -

i trying compare distribution of 2 samples see whether alike , running ks test below:

for real life data, p value less .05 (assuming default alpha) indicating reject null hypothesis. however, before concluding wanted try test @ different level of significance .01, reason same value , error when specify "alpha=.01"

"warning: alpha= option in proc npar1way statement used hodges-lehmann confidence limits."

options ls=72 ps=66 nonumber nodate; data in; input resp sample $ @@; cards; 20.30 1 22.53 1 25.70 1 13.23 1 29.67 1 24.46 1 26.07 1 19.35 1 17.813 1 16.00 1 15.30 1 32.90 1 10.56 2 28.13 2 19.94 2 11.03 2 8.093 2 12.95 2 21.14 2 32.50 2 10.90 2 ;  proc npar1way data=in edf; class sample; var resp; exact ks alpha=.01; run; 

could point out i'm doing wrong here ?

thanks

use / indicate alpha option in exact statement. doesn't affect p-value affect confidence intervals.

proc npar1way data=in edf; class sample; var resp;  exact ks /alpha=0.05; run;
