<P><FONT SIZE=2 FACE="Arial"> I have posted in here a few times asking questions about data filtering. I have part of a code set-up for removing header information and then extracting a column of data (thanks to the python list for help and book recommendations) then writing the column to another file. My question is twofold: How do I maintain a columned format when I write the data to a new file? When I place the data extracting part of my program into the big filter program I receive the error (I am guessing I have an indent problem or syntax):</FONT></P>

<P><FONT SIZE=2 FACE="Arial">"There is something to be learned from a rainstorm. When meeting with a sudden shower, you try not to get wet and run quickly along the road. But doing such things as passing under the eaves of houses, you still get wet. When you are resolved from the beginning, you will not be perplexed, though you still get the same soaking." - Yamamoto Tsunetomo</FONT></P>
