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.
