Does putting these things in and being absolutely explicit make things clearer ? I don’t think so. 100 ) #etcĪnd although the values don’t overlap and all there isn’t an “Output this for ‘none of the above’” (we’ve written the case for each of the days) the writer has carefully added Break or Continue to each of the blocks and added a default block which only contains Continue. It has another use in loops to save doing the job of an if which runs a large amount of the script conditionally, continue says “Skip the rest of the work for this item and Continue-with-the-next one.”, it has a companion, break which says “Skip the rest of the work on for this item, and don’t bother with any remaining ones.” Here’s a slightly contrived example, finding primes with the sieve of Eratosthenes $Primes = foreach ( $i in 2. There are two other sort-of “goto” commands which can be allowed: Continue has one use if you use trap instead of try/catch, which is to resume execution at the line after the error.

However when the “etc” part of that code goes on for a whole screen it gets hard to see that nothing else happens if $result evaluated as true in that case putting in a comment (“If result was set, the work is complete”) and using return can make things clearer.
