Hash function programming

Question

I have program for a hash function:

 H(a || b || g || y1 || y2)

where a,b,g,y1,and y2 are inputs. Can anybody tell me what to do with these inputs if I am using SHA-2 as my hash function? does this mean I have to either concatenate all the inputs, do the OR operation, or something else??

Are you using hash for security checks or for lookup of some sort? — exebook

You can xor them, if these inputs are numbers, or concatenate them using sentinels, if they are strings.
