Hi.
If you sort your alphanumeric list, you will, of course, already know that the alphas sort before the digits, so the first digit will be down a bit. But how long is that list? After sorting, if you loop through using the "repeat for each..." variant and exit accordingly, I cannot imagine that it would take more than an instant to find the first digital char. Old fashioned but trusty. I have done binary searches, splitting data in halves as you go so that you cut down processing time, mainly finding stuff in long HC datasets.

Hello, I have a list with alphanumeric and numeric content. After sorting numeric I would like to find the first line with a numeric first char. (the non numeric lines before can contain also numeric chars). I would like to have a kind of lineoffset(isNumber(first char.),list,), but that's not prebuilt. What would be the fastest or most straight forward way to look up such a list? Just looping through? Testing the first char every half of the list in a loop? Or is there a function I don't think of? Thanks for any pointers Tiemo _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
