I trying to create an array containing the
difference of the two other arrays.  When I create the
arrays manual I have no problems.

a = ["0001", "0002"]
b = ["0001", "0002", "0003"]
c = b - a
puts c 
c -> 0003

However when the array is created from data in a file
d will equal the first array not the difference
between the two.

File.open("datafilelist.txt").each { |h| data_files1
<< h}

d = data_files1 - data_files
puts d
-> 0001, 0002

Thoughts?
