Hey there,
just got the pickaxe book, and i am working thru the beginning.

one example prog is this

#!/usr/bin/ruby

def fib_up_to(max)
i1, i2 = 1, 1
while i1 <= max
yeild i1
i1, i2 = i2, i1 + i2
end
end

fib_up_to(1000) {|f| print f, " "}

when i try to execute it from a terminal, i get this:

../testl.rb:6:in `fib_up_to': undefined method `yeild' for main:Object
(NoMethodError)
from ./test.rb:11

am i doing something wrong? i have this installed in debian sarge.

thanks

Typo: "yeild" should read "yield".

geez, nevermind. guess it would help to spell yield correctly !

'i' before 'e', except after 'c'.

Offhand, I'd say you misspelled "yield". :-)

It's a spelling error. Try "yield." ;)

thanks, gents. i don't mean to waste fellow coders time. I am new to
ruby (installed it yesterday) and i thought something was wrong with my
interpreter. Now i think something is wrong with my keyboard. I find
that in most of my code, a problem is usually traced to somewhere
between the keyboard and the chair .

thanks,

:) You have misspelled "yield".
