I think that you will be just fine the way it is. If you are in a real
performance pinch such as a batch job that calls a routine to validate a GL
account number then you would want to make that a module. But in your
example I would encourage you to leave your programs as is. The user is not
going to notice the increased interval between program calls of this nature.
