Hi,

Can you post your code?

Generally, programs requiring user interaction do not work well in
programs like SCiTE and should be run from the command line.

Here is an example of using gets:
puts "What is your favorite color?"
color = gets
if gets == "red"
puts "that's mine too!"
else
puts "bad choice..."
end

puts ' What is your full name?'
name = gets.chomp
puts ' Did you know there are ' + name.length.to_s + ' characters'
puts ' in your name, ' + name + ' ?'

The Windows command prompt closes after the program is done running
unless the program was run by an already existing command prompt IIRC.
My advice would be to opening a command prompt, and running it from an
already opened command prompt. This should allow you to see the output
of your program.

Start -> Run... -> cmd<enter> -> help<enter>

Navigate to the directory you saved the Ruby script, and type "ruby
name_of_your_script.rb".

This assumes that Ruby is in your path. Otherwise, you'll have to type
in the path to ruby.exe, too (For example: "c:\ruby\bin\ruby.exe
your_scrupt.rb").

For testing purposes you should use irb (irb.bat or whatever the name on
windows was), this way you are independent of a GUI (and bugs or
problems inside that GUI) too.
