This block of code works and it's easy to see why:-
def add_two_num
p "gimme two numbers. first : "
x = gets.chomp
p "second : "
y = gets.chomp
out = x.to_i + y.to_i
p out
end
add_two_num
This next lot --doesn't-- and I get the feeling that it has something to
do with scope, maybe within the case block. Am I right?
def
test_gets_positive p "gimme a number : "
ask = gets.chomp
n = ask.to_i
case
when n < 0
puts "this number is -ve. i ain't gonna play no more! STOP!"
exit
when n = 0
print " this number is +ve! this it\'s square:"
p n*n
end
end
test_gets_positive
wtf has happened to n?

In this code the line:
when n = 0
looks wrong
Shouldn't it be:
when n >= 0

Sheesh! All is working now and I can move along 
ty! This is all that I wanted to do:-
def grab_spit_number_case
p "enter a digit : "
gets.chomp
number = $_.to_i
puts number
p number.class
case
when number < 0
p "this number is -ve. can't play: STOP!"
when number == 0
p "can\'t do much with a Zero. You sure you gave me a +ve number?"
when number > 0
p "this is your number: #{number} and this is it's square#{number*number}"
else p "what number did you pass to me exactly? can't seem to determine it"
end
end
grab_spit_number_case

p "this is your number: #{number} and this is it's square#{number*number}"
FYI, the word "it's" is only used for the contraction of "it is"; the
possessive form is always simply "its". Understandable confusion,
since the possessive of most other nouns does use the apostrophe. (As
in "the dog's house" or "Phrogz's annoying English pedantry".)
