If you are pre-V2R5 then the probably the best way to do this is with a case statement:

Case when field_a > field_b and field_a > field_c and field a > field_d
     then field_a
     when field_b > field_c and field b > field_d
     then field_b
     when field_c > field_d
     then field_c
     else field_d
     end

This is surely not the sleek, simple solution you were looking for, but without user-defined functions (and any predefined function that does what you want), I think this is the easiest approach.
