This is correct. integer(n) should return false.

This is correct. The character '3' is ASCII 51.

What? Does sequence(n) return zero?

> fails the sequence(n[1]) test

Good. n[1] is an integer - 51. Also known as character '3'.

Of course - its a sequence.

> passes the atom(n) test -- = 51

What? Does atom(n) return true?

WHat? I don't know what you mean by the 51-3. Do you mean 51 minus 3 as the
value of the only element in a sequence?

> debug says junk = 51 -- atom

Correct.
> What happened to the "3" in n ? It is acting like i used a '3' !

You did use a '3'.  EUphoria's string notation is a shorthand for this...

  "3"  is equivilent to {'3'}

Just as "Derek" is the same as {'D', 'e', 'r', 'e', 'k'}
