Hi Gerald,

That's a good idea, not all of the packages always use the new attributes. Is there a solution for the packages that are going to use the new additions?...

Your snippet does not validate the routing number "111000960" -- or any other number I tried ending in 0. In this case, it rerturns 10 not 0.

So this seemed to...

I find it very hard to objectively evaluate my skills...

I'd say I'm just exactly 'in the middle' - neither bad nor exceptionally good.

I think that I have a decent knowledge...
