I've come into this a little late, no internet for a week or so, but be aware that switch is slower than if-then-else-end if, no matter who many nested ifs are required to do 'the same' as a mult-case switch statement. It's only a couple of milliseconds over 1000 executions, but it is slower. If what you want is as stated, then I think you'd be better served by: if (gTimeTest is empty) then --do empty stuff else --do full stuff end if Having said that, I've started to use switch a lot because what appears at first glance to be a simple yes/no,true/false,black/white, after a week of tweaking I realise that yes/no/maybe,true/false/no comment, and black/white and all the other colours of the rainbow also need to be considered: and this is where switch is so easy to read and understand. Here is another version for your switch command: switch case (gTimeTest is empty) --do empty stuff break default -- do full stuff end switch Which then makes it easy when you decide to do things based on the exact contents of gTimeTest switch case (gTimeTest = "1:00") revSpeak "It's one o clock" break case (gTimeTest = "2:00") revSpeak "It's too o clock" break ... ... case (gTimeTest contains ":30") beep break case (gTimeTest is not empty) --do whatever default answer "There is an error, gTimeTest is empty" end switch _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
