When I tried conjoining the if-then statement like that, both with 'or' and with 'and' I found it to be 2 to 3 milliseconds slower than separate if-then statements.

At first I thought it would be slower than the one that most of us opted for, i.e. test each condition sequentially and if the test fails at any level go on with a "next repeat". I thought RR would test all the conditionals in your handler (in ...and ... and...) before moving on to the next repeat, but Scott Raney was too smart for that. Apparently, at the point where the "and" test fails, RR decides there is no point in proceeding with the others, so...... next repeat. The speed is about the same for either method. Jim P.S. If you submit your solution to NPR and your name is drawm, you are in danger of being called on Sunday for another test of wits. My mind works too slowly for this kind of exposure. _______________________________________________ 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 _______________________________________________ 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
