Program ends to quickly

Just for an example:

#!/usr/bin/ruby
print "Hello World\n"


It makes a black window appear, the words "Hello World" Pop up and the screen disappears almost to quickly to see it. How do I make it stay up until I tell it to end (i.e. Hit the enter key to close?)

I appreciate any help I can get.

What you wrote is a console program, so you ideally you should open a command line and run it from there. Get used to doing so, as many of the programs and tools you will use will be command line programs.

But if you want to create a kludge and keep the window open, ask for user input. Doing something like kludge = gets at the end of the program will do the trick.
