Here is an example of the data. The second file handle does not have unique keys so I can't build a hash to test with it.

There are two source files:

#Listings  Filehandle <CREATEFILE>
Source1=Times
Source2=DJNews
Source3=Yahoo

#Repeat Stocks  Filehandle <F>
F=Source1
F=Source3
LNUX=Source2
AMZN=Source1
INTL=Source3
INTL=Source1
