I think the difference must be that, in my test, I was checking for single thing.

I found that counter-intuitive, so I checked things out with 4W RevBench (thanks, Richard). I find that the switch statement consistently runs some quite a bit faster on four tests. Obviously the value of x here will be the major factor in determining the total run time in the nested-if case. -- test 1: put 4 into x switch x case 1 put x into y break case 2 put x into y break case 3 put x into y break case 4 put x into y break default put x into y end switch -- test2: put 5 into x if x = 1 then put x into y else if x = 2 then put x into y else if x = 3 then put x into y else if x = 4 then put x into y else put x into y end if end if end if end if value of x: % faster (100k runs): 1 0 2 15 3 25 4 35 5 35 -- -Mark Wieder [EMAIL PROTECTED] _______________________________________________ use-revolution mailing list [email protected] http://lists.runrev.com/mailman/listinfo/use-revolution _______________________________________________ use-revolution mailing list [email protected] http://lists.runrev.com/mailman/listinfo/use-revolution
