Subject: Re: A simple question regarding ruby method argument

I am trying to write a method that changes the value of two arguments. 
Stripped to the barest essentials, something like this:

def munge(a)
    a = a + 1
end

zot = 3
print zot, "\n"  # this should (and does) print '3'
munge(zot)
print zot, "\n"  # this should print '4'.  We wouldn't be here now if it 
did!

Now, if I try the amend method given by David A. Black, it works as 
expected.  But it's passing a string object, not an integer.

Surely there is a way to give a method _something_ so that it can return 
values to the caller.  Of course, if I only ever had a single value to 
return, I could make it the return value, but that's just begging the 
question.

Thanks in advance,
John
