From: Charlie Ca on 10 Feb 2010 18:14 Hello World, I am new to programming and am writing a program in ruby that serves as a tutorial for absolute beginners. It's heavily reliant on if & else. I was wondering if there is a method for exiting a program. Here is the Context; puts ' If you would like to begin, press enter.' confirm1 = gets.chomp if confirm1 == '' puts 'OK, Lets begin!' else puts 'Try pressing enter this time.' gets.chomp if gets.chomp == '' puts 'Press enter twice' else puts 'Next time press enter ;( ' end end puts ' If you are reading this you have already downloaded' puts ' the interactive ruby console with the' #... When they don't press enter the 2nd time, I would like to exit the program. Thanks, Charlie -- Posted via http://www.ruby-forum.com/.

Thanks, Charlie If you need to ask the mailing list a question like this, then you are not ready to be writing Ruby tutorials. Sorry, but that's the way it is.

I guess I should stick to 'Hello World' programs. -- Posted via http://www.ruby-forum.com/.

I thought that on first reading too, but after I read it again I figured he meant he was writing a program as a solution to a problem in a tutorial he's going through. Anyway, Charlie, the method is simply 'exit'. It's a class method of the Kernel module, so it will be invoked if you don't specify a receiver object.

Oh, if that's the case, then yes, my response was uncalled-for. I did interpret the OP's original post as saying he was *creating* a tutorial. > > Anyway, Charlie, the method is simply 'exit'.
