I have 8 brands in a dataset, with possible values of 0-9 for each of them.

I want to write macro code, where I can look for ties in the values of the brands, and create a flag. e.g if brand1=brand2 or brand1=3 or......brand1=brand8 or brand2=brand3........ then flag=1

b1 b2 b3 b4 b5 b6 b7 b8 flag 2 0 5 6 3 0 0 0 0 3 0 4 0 0 3 2 0 1

Thanks for your help, Shukla

The easiest answer is to take working code and rewrite it for your case

See SAS programs of Donald Knuth's algorithms for sorting and searching on SAS community wiki:

The easiest and most obvious for your purpose is the Shell Sort
