Sorry, but it is not clear what you want concatenated.

Please explain the logic that lets you go from the input data to the output data. Please give a step by step example.

I'm not going to format each individual value, but I'm assuming this is what you wanted.

data want;
	set have;
	length acnoth $200.;
	array v [*] ther -- other;
	do i = 1 to dim(v);
		if not missing(v[i]) then acnoth = catx(', ', acnoth, vname(v[i]));
	end;
run;

In future posts, please provide more information - we can only make assumptions. If you have actual character values associated with variables, please provide those too.
