David Cuny has one on the Recent Contributions page. With commas.e (mine,
yeah, a shameless plug... :), you can do something like this:

number = remove_commas(gets(0))

To get a number. If you used get(), you'd need to do this:

junk = get(0)
if junk[1] = GET_SUCCESS then
    number = junk[2]
else
    number = 0
end if

Also, if the user just pressed ENTER, without typing anything, get()
would go to the next line and keep waiting until you type something other
than whitespace. My method assumes 0. (Like BASIC's INPUT) It also
allows:

$3,000
or
50%

Then again, it also allows:

4,4,4
(444)

and

44$45%%%443
(4445443)

Oh well....

(PS, if you coupled David Cuny's with mine, you'd have a SLE like in
TextGUI that can have default values like $5.00 or $5,000.00 [That's what
I did in one program that used TextGUI (using the TextGUI input stuff
[SLE]), and I think the effect is neat..])

Any better ideas? (Like a function to handle all of this, maybe something
that accepts a % code (%d, %f, etc) to determine the return value. (%c
would be single character [ie wait_key()])
