Gordon Hartley-Bennett...! You're a raving genius!!! ;-)
- "considering case" speeds up text comparisons considerably.
- arranging the most frequently occuring letters first also
speeds things up, as Nigel and I have worked out in the past.
- placing any static value that is need more than once into a
variable, like "count inputtext," is always a good idea.
- a try-statement to handle out of bounds is often a nice way
to avoid repeatedly checking the lengths of strings.
When all is said and done, we might save a good 100 whole milliseconds!!!
(Which, of course, is 0.1 of a second). ;-)
