Refactoring in the Small

Keep code's functional properties, while improving non-functional properties
- Readability
- Maintainability
- Portability
- Reliability
Can be performed in the large (architecture), or in the small (code elements)

Illustrative Example

        if (*cp == 0)
                break;
        if (*cp != ',' && *cp != ' ')
                goto bad;
        cp++;

Changed into:

        if (*cp == 0)
                break;
        else if (*cp != ',' && *cp != ' ')
                goto bad;
        else
                cp++;
