Re: odd behaviour in rule delayed


Francisco:

I think the problems were twofold. I dropped "list" in favor of a since list
conflicts with List. Then I changed the iterator from "k++" to "kk++".

Cheers,
Hank Foley


In[18]:=
a = {1, 0, 1, 0, 0, 1}
kk = 0; newlist = a /. 1 :> ++kk


Out[18]=
{1, 0, 2, 0, 0, 3}
