That's the result I get as well.  There's no way to change c without 
changing s, with that initial value of s --- and I was restricting myself 
to that.

It can be done easily if s = {"a", "b", "c", "d", "e"}, however.

ss = {"a", "b", "c", "d", "e"}
dd = {1, 5, {3, 4}, 7, abc, {0.1, 0.001}, 3.1415}
ToExpression[ss[[3]] <> "=" <> ToString@dd[[4]]];
c
ss

{"a", "b", "c", "d", "e"}
{1, 5, {3, 4}, 7, abc, {0.1, 0.001}, 3.1415}
7
{"a", "b", "c", "d", "e"}
