debug doesn't work for me!

E:\Ruby\work>ruby -r debug fact.rb
Debug.rb
Emacs support available.

e:/ruby/lib/ruby/site_ruby/1.8/ubygems.rb:4:require 'rubygems'
(rdb:1) [1,4] in fact.rb
e:/ruby/lib/ruby/site_ruby/1.8/ubygems.rb:4:compile error
e:/ruby/lib/ruby/site_ruby/1.8/ubygems.rb:4: parse error, unexpected kIN,
expect
ing $
[1,4] in fact.rb
^

Set breakpoint has the same problem.

Notice there also seems to be a line missing before the (rdb:1) prompt.

def fact(n)
if n <= 0
1
else
n * fact(n-1)
end
end

p fact(4)

can you paste your fact.rb source

But it doesn't stop at line 2!
And this command from the manual doesn't parse:
[1,4] in fact.rb

Try this:

(irb:1)break fact.rb:1
(irb:1)c

E:\Ruby\work>irb
irb(main):001:0> break fact.rb:1
SyntaxError: compile error
(irb):1: parse error, unexpected tINTEGER, expecting tSTRING_CONTENT or
tSTRING_
DBEG or tSTRING_DVAR or tSTRING_END
from (irb):1

If you've been running this in windows, I think ruby includes a file in
order to work smoothly with the windows command line. Your breakpoint
were getting set in that code, not your code.

Well, that's no use!
Notice that Senthilnaya's code didn't work either
Could it be that Ruby debug simply doesn't work under XP?
