Functional Cohesion (inspired by P.J. Plauger)

When you can describe a module of code in a simple sentence, then you probably have a re-usable piece of code that will be around for awhile.

Routines with descriptions like "TOTAL.AND.PRINT" indicate that the routine does not do one thing and do it well. A more useful and maintainable implementation of this code would separate the TOTAL & PRINT logic into two different routines.

Changes to the new routines TOTAL & PRINT should be improvements that benefit all users of the new routines.
