Thanks Ed,

That code works very well.  I discovered a problem in the original
file I was working from though. Some records in the file don't start
with LG so I need to include a condition to only write LG records to
stdout.  The file really looks like this:

FL1ABC
LEX123
LG1XYZ
LG2DBA
LG3PYZ
FL1CBA
LEX999
LG1QWE
LG2ZXC

Using the example above I would only want to write FL1 records along
with LG records, ignoring LEX records.

FL1ABCLG1XYZ
FL1ABCLG2DBA
FL1ABCLG3PYZ
FL1CBALG1QWE
FL1CBALG2ZXC

I tried a couple of things in the code but I just can't get a handle
on the proper syntax to accomplish it.

Thanks again.
