Subject: Re: why I get an empty hash?

Look at what happens when the array has one element:

data = ["A"]
result = table(data, 2)


(1)
table(array=["A"], word_size=2, word='')
---------------------
hash_table = {}
e = "A"

if false
else
  (2)table(array=["A"], word_size=1, word='')

#Execution halts in the first table call until
#the return value of this recursive table() call can
#be determined...


(2)
table(table(array=["A"], word_size=1, word='')
--------------------
hash_table = {}
e = "A"

if true
   hash_table["A"] = 0

return {"A" => 0}

#Now the return value for the recursive table() call has been
#determined, so the return value can be substituted in (1) and
#execution can continue...


(1)
------------
=begin
hash_table = {}
e = "A"

if false
=end

else
  {"A" => 0}  #from (2)

return hash_table
