newbie question - undefined method `replace_session_timeout' for main:Object (NoMethodError

Hi,

I'm a newbie to ruby, and programming really...

I'm trying to write a simple script that will make a small change to a
text file.

Here's the code:

#script for changing the sessionState timeout to 30 minutes

f = File.open('C:\Inetpub\wwwroot\GT\web.config', 'r+')
f.each do |line|
if /sessionState/ =~line
offset=line.length
line=replace_session_timeout line
f.seek(-offset, IO::SEEK_CUR)
f.print line
end
end
f.close

def replace_session_timeout line
int = /</=~line
spacer = line[0..int-1]
result=line.replace spacer + "<sessionState timeout=\"30\"/>\r\n"
end

When I run this script I get the following error:
>ruby GT_SessionTimeout_1.rb
GT_SessionTimeout_1.rb:7: undefined method `replace_session_timeout'
for main:Object (NoMethodError)
from GT_SessionTimeout_1.rb:4:in `each'
from GT_SessionTimeout_1.rb:4
>Exit code: 1

I guess there is something wrong with my method call, but it looks
syntactically correct to me.

I've paged through the pickaxe book and online but, to be honest, I
don't think I understand the problem enough to search well for a
solution.

Any ideas?

Thanks much,
Warren

The Ruby interpreter needs to see the definition of
replace_session_timeout before it is called for the first time. Just
move the definition above the body of the script.
