Execute more common evaluations first! Short-circuit evaluation is a feature of most languages where once an evaluation evaluates to False, the compiler evaluates the whole expression to False, exits and moves on to the next code execution line. In Access VBA, the if statement does not support short-circuit evaluation but you can mimic it. Use either an if..else if..else if statement or nested if statements. You will find that your code that makes use of this technique will be clearer and easier to maintain than the short-circuit equivalent and will execute faster than ignoring this issue.
