1. atoms, grrrrrr

Can someone explain this to me:

code:
sequence s1
integer at1

  if at1 < length( s1 )

data:
s1 = {{116't',104'h',101'e'},{99'c',97'a',116't'},{97'a',116't',101'e'},

 at1 = 3

error:
true/false condition must be an ATOM

You never assigned a value to at1 before you
asked it whether it was less than another value

Is an integer an atom?

Peoples, i did provide the values, as printed out in ex.err, they had values.

And it is what i thought it is, as i assigned them and as printed out in ex.err.

I did, it's:

if at1 < length( s1 )

That is how i defined it, the line just above is what ex.err printed out, which
is the
same thing and correct, right?

So why is the code you wrote, which is exactly the code i put into this other
program,
working by itself, and not in the program? The boolean test line is the same,
and the
vars are the same.

I'm sure that's just a typo, wouldn't it be 5?
