Subject: undefined method `+' for nil:NilClass (NoMeth

Dear All,

Am trying to create a character generator in RUBY. it will create
characters from a-z in the folowing way:

a
b
c
z
aa
ab
ac

and so on. sor here is my first code:


Array = ['a', 'b', 'c' ,'d', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l',
'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

$Text = "";
$OldText = "";
$OldText2 = ""
$OldText3 = ""

def Join()
 $Text = $Oldtext3 + $OldText2 + $OldText + $JOB
end

while (1)
Array.each do |$JOB|
Join()
 puts $Text
end
end



Eventually, $oldtext2-3 will be filled in later, bt am geting this
error:

C:/WINDOWS/thread.rb:10:in `Join': undefined method `+' for nil:NilClass
(NoMeth
odError)
        from C:/WINDOWS/thread.rb:15
        from C:/WINDOWS/thread.rb:14:in `each'
        from C:/WINDOWS/thread.rb:14

C:\WINDOWS>





Could someone please shed some light
