Being on the digest version of the list, I am coming in late on this one.
The thing that confused me in the beginning about Run Rev and numbers is that they treated in a manner which depends on the context. For example if you write:
put chars 1 to 4 of 123456 into theResult
Then theResult is 1234. Clearly 123456 is being treated as a string of characters.
And if you write:
put 123 & 456 into theResult
Then again these are treated as characters and theResult is 123456.
But if you write:
put chars 1 to 4 of 123*456 into theResult
Then you find the surprising thing that theResult is 46088
But if you write
put chars 1 to 4 of (123*456) into theResult
Then theResult is 4608, which is what you would expect. The parentheses force an evaluation.
If you want to demand that the characters be treated as characters and not numbers, use quotes. Then if you write:
put chars 1 to 4 of "123*456" into theResult
Then theResult is 123*, as you expect.
Moral: With flexibility comes responsibility.
But the value of being able to treat the number as a string is that you can write a handler to format the number. For example, you can format 1234467 as 1,234,567 or 1.23 * 10^6 or whatever.
