Nifty... so now you get input from the user.

Time to learn how to create files and run those.

Do you know how to change directories in DOS?

kind of but not to well. I know i would type C: or something to get it on my drive but not sure.

[wtd]

Yep.

First off, save the following simple program in a file named "greet.rb".

code:

puts "Your name is?" name = gets puts "Hello, " + name + "!"

Remember where you saved it.

[dsantamassino]

ok i did save it.

[wtd]

Open up a command prompt. Start -> Run, type "cmd" and hit enter.

Now, get to the drive where you saved the file.

I went to my C drive and then i typed in greet that didnt work so i typed in greet.rb and that didnt work..

[wtd]

Did you save the file at the root of your C drive?

[dsantamassino]

Yes

Type "dir /B" and hit enter. See if greet.rb is in that list.

[dsantamassino]

No its not there.

[wtd]

I thought not.

You'll need to "cd" to the directory (or "folder") greet.rb is in. The basic format is:

code:

C:\> cd "the folder\the file\is in"

[dsantamassino]

Not a clue what to do here. this is what i typed and didnt work.

It was already pointed to the C: drive so on that line i typed.

cd C\greet.rb

Nono, what he means is that first you have to cd into the directory with the .rb file in it. So if the .rb file is in "C:\Documents\Programming\Ruby\" then type:

code:

cd c: cd Documents cd Programming cd Ruby ruby greet.rb

Or, if you're feeling adventurous,

code:

cd c:\Documents\Programming\Ruby\ ruby greet.rb

If it's already IN root C;\ and that's where you are by defult, you don't need to cd anywhere. Just: ruby greet.rb

It already on my root C so i typed ruby greet.rb and this is the message im getting.

ruby: No such file or directory -- greet.rb (LoadError)

Ok... the file is obviously not in C:\, so trying to run it from there will not work.

Where exactly did you save the file? Use the search feature if you have to.
