in reply to Re^2: Next permutation
in thread Next permutation

Your requirements are cryptic for me.

Please note that you can easily implement any "swap" with array slices, like

@a[0,1]=@a[1,0]

and @a=split//,$number

will initialize it.

Now you know everything needed to implement your ideas.

HTH! :)
