This is what I got, but there's some errors, or attributes, depends on how you see it.  It'll take the number out, but it will put the number in order.
var number : int := 0
var hold : string := ""
var chars : string := "123abc"
for i : 0 .. 9
    for q : 1 .. length (chars)
        if chars (q) = intstr (i) then
            hold += chars (q)
        end if
    end for
end for
number := strint (hold)
put number
use "1231abc" and see for yourself.  I can't think of anything else right now, but i figured this was better than nothing.  :?

Here yas go.  I did it backwards, here's the final good copy.
var number : int := 0
var hold : string := ""
var chars : string := "423ab1c"
for i : 1 .. length (chars) %Checking Every Character
    for q : 0 .. 9 %Checking If There's a Number There
        if chars (i) = intstr (q) then
            hold += chars (i) %Adding the Number to a String
        end if
    end for
end for
number := strint (hold) %Converting the String to an Int
put number

What you do is check every character in the string to see if there's a number, if there is, add it to a variable that can hold the information, then transfer the information to an integer variable.

yingmu,

Unless you are trying to go above and beyond I've said that you only need to worry about one digit numbers.

why should he only stick to 1-digit?
