Smell Of The Day:
Long Parameter List
If you have too many parameters (3 or more), then change to use a typed GROUP or CLASS structure. Call it ProcName_Parms, or something like that.
If you use a CLASS, then its constructor can set default values.
If you need to track omitable state, then add extra elements to the group/class to indicate that. (In this case, CLASS is better, because you can manage that with Setters and Getters.)
