What is conditional compilation?
Conditional compilation is typically used to compile the same program for different platforms. It is also used to prevent debugging code from appearing in an executable file. Code excluded during conditional compilation is completely omitted from the final executable file, so it has no effect on size or performance.

How does an if function work?
An If operator that is called with three arguments works like an IIf function except that it uses short-circuit evaluation. An IIf function always evaluates all three of its arguments, whereas an If operator that has three arguments evaluates only two of them. The first If argument is evaluated and the result is cast as a Boolean value, ...
What happens if the first argument is false?
If the first argument is false, only the third argument is evaluated and a 0 is returned. Therefore, when the divisor is 0, no attempt is made to perform the division and no error results.
