Oke,
I can try this but im afraid the test which test a particular
error il fail.
The error messages are given.
And I miss you. yes, SequenceableCollection has with do:
but should I add the with count to it ?

SequenceableCollection has with:do:.

With that code I get a few problems but this is working
distanceStrand1: aString strand2: aString2
aString
Nice one but I learned I can never
trust the input of a user

I will try it tomorrow after some good sleep.

Hi Roelof,
Maybe something like this:
String>>hammingDistanceTo: aString
" Answer the amount of substitutions between the receiver and
aString. Both must be of equal length "
^ (1 to: self size) count: [ : i | (self at: i) ~= (aString at: i) ]
