Name

IF-04: Use CASE and IF consistently

Synopsis

Any conditional statement that can be expressed as an IF statement can also be expressed as a CASE statement—and vice versa. While you might heatedly debate the relative benefits of each over a few beers after work, it's fairly clear that you can write high-quality code no matter which statement you employ.

However, randomly alternating between the two statements does not lead to high-quality code. It's harder to compare the logic of two routines if—for instance—one expresses its branching logic with the CASE statement while the other uses IF. So try not to mix IF and CASE arbitrarily within your programs.
