How do I add p-values to Dunn test for all two-sided pair-wise comparisons ?

IYH Dear SAS Community

I am trying to help a colleague. I have no experience w SAS code. She provided me this Dunn test code (attached txt file). I attempted via AI code generators to add a PROC MULTTEST procedure to perform the multiple comparisons and calculate the p-values but the AI failed at generating valid sas code for this addition. 

Would someone kindly be able to assist me (see Dunn macro below)  to add the p-value calculation? Any help muchly appreciated.

I Y H This is OP. I tried a different more powerful code gen to correct the erroneous V 1 and it produced V 2

Would someone kindly test out whether the V 2 patch to the Dunn macro in OP would work (I do not have access to SAS code executors alas). The V 1 patch and V 2 fix patch are below.
Thank you very much.
