Hi Peter, "goto" is an ancient philosophical paradigm.
These type of subroutines were replaced with functions (defined by 'def' 
in ruby), it looks like this:

def print_hello(name)
 puts('Hello, '+name)
end

print_hello("Peter")
print_hello("Dor")
print_hello("Everyone")

the output will be:

Hello, Peter
Hello, Dor
Hello, Everyone
