in thread what is the difference between index and rindex

Hmm, I always thought the "r" stood for "right". As in BASIC (the functions Left$, Mid$, Right$ — Microsoft's DOS based QuickBASIC had them).

    What was really cool is that MID$ was an lvalue and, if I remember correctly, could be assigned a string of a different length from its present value, i.e., you could replace n characters in the middle of a string with m new characters. Before I discovered Perl, I used to think QBasic was *the* language for string manipulation and text-munging jobs. (Of course, these days lots of languages can do that stuff. But back then, Borland C++ was the hot new thing, and it didn't have *anything* like MID$.) ISTR that LEFT$ and RIGHT$ had these properties too, but MID$ was the most general and therefore the most useful.


    Sanity? Oh, yeah, I've got all kinds of sanity. In fact, I've developed whole new kinds of sanity. You can just call me "Mister Sanity". Why, I've got so much sanity it's driving me crazy.
