You may wish to look back at these two threads, lots of benchmarking, sorry I haven't figured out how to create links to old threads :-(
Subject: if statements vs case Date: 27 feb 07 From: Hershel Fisch Subject: switch case question Date: 10/22/06 From: Mark Swindell Basically what has been said so far is correct, timings are similar BUT Dar Scott in the 2006 thread determined those cases (sorry for the pun) where one will be faster than the other. I believe the general conclusion was, if speed meant everything to you, you'd need to benchmark both. Secondly, Randall Reetz wrote: A better word for "switch" could have been "first match" as it presents an > ordered list of conditional tests at the same level, once a match is found > the interpretor exits the switch list. > Whilst this is the 'normal' behaviour we think of, it is not the only behaviour. If the 'break' keyword does not follow a 'case' structure, then the statement flow does NOT exit the switch list. I use this all the time, its a great feature of switch statements that allow the easy creating and modification of OR conditions switch tName case "Bob" case "Bill" case "Ben" put "boy" into tGender break case "Sue" case "Sally" case "Sarah" put "girl" into tGender break default answer "A Name I Don't Know" end switch I love switch for the benefits of script manageability. IMO they are very easy to understand, very easy to figure out where to include extra case structures if needed - something I always struggled with in large nested if-then-else structures. Another thing I like is they are fairly easy to manipulate if you need to make some minor speed improvements. During development, simply by adding a counting mechanism you can determine which cases are triggered most often and therefore move those to the top of the structure. Lastly, I've become fond of using the default structure as a logic error catch all, as in the above example. If it's yes/no, on/off, true/false, 1/0 then I use IF, but too often I discover it's yes/no/maybe, on/off/sleep, true/false/no comment, 1/0/-1 so I go with SWITCH. _______________________________________________ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
