Thanks Dave and Dennis for your suggestions. I followed the examples and
created a script to read the file I sent earlier, but it seems to be I am
still getting some header information in the column I am trying to extract.
Attached are output and script that was used, any suggestions to overcome
this issue.
Debasish.
