Split the line:

def amethod localvar = 10 puts( localvar )

Then run via:

irb variables.rb

Per the error messages, and my post above, you need to split your def lines.

Can you please paste the text of you command windows, into a CODE block, or alternatively past the screen grabs into Paint, save as a jpg or png, and upload directly (the results will be visible on page), as it's a pain to have to download, scan for viruses and open a Word document, and a real pain when you only have a phone / tablet to hand.

You need to invoke you defined methods  e.g.

Alter your variables.rb to:

localvar = "hello" ;
$globalvar = "goodbye"
def amethod
    localvar = 10
    puts( localvar )
    puts( $globalvar )
end
def anotherMethod
    localvar = 500
    $globalvar = "bonjour"
    puts( localvar )
    puts( $globalvar )
end
puts "Invoking: amethod"
amethod
puts "Invoking: anotherMethod"
anotherMethod

Open in new window


Then type:

ruby variables.rb
