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.

code:

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.

code:

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?
