( #3333=superdoc: print w/replies, xml ) Need Help??

Three questions:

  1. What is $validator supposed to be? A ref to a subroutine or something else?
  2. None of the output before the prompt is visible until after the prompt is done, what do I do if I want to see that before the prompt?
  3. What if I'm not piping the script into less? How can I see everything after the prompt?

My example code:

print "A"; print "B"; prompt("Question1:", "", "Wrong answer try again:"); print "C"; print "D"; sub prompt { # same as above excpet I commented out the if $validator-> part }

when I do

./ | less
all I see at first is:
After I type my answer (which I can't see), I'm in less with just
I'd like to be able to see A and B too (and before the prompt)

Also if I don't pipe the script into less I don't see anything after the prompt (yes I realize that wasn't part of my original question but it should have been).
