Thank you to all who answered.

And the right answer is....  "if" vs. "If".

Special thanks to those, who realized that my "a, b, c, d" example was just
a demo for my problem and not a real attempt to assign values to a b c and
d. But at the same time {a, b, c, d} = {1, 2, 3, 4} was a suprizing
construct which raised another question.

Supose A = {a, b, c, d} and I want to replace the first element with "e".
Apparently A[[1]] = e will have the effect of assigning e to a and not
leaving "a" alone and setting A to {e, b, c, d}. How would I accomplish the
latter and not the former?

Thanks!
