RE: string editing suggestions

I'd use a ten slot array of counters for each digit.  It would be easier
with a zero based array, but you just convert the character to a number and
use that as the index of the array.  Something like eval array(numchar + 1)
= array(numchar + 1) + 1.  You could have a loop controlled by the number of
numeric characters in the string and array(numchar + 1) being less than the
illegal value.
