I have this appliaction that spits out a format that is not usable for me,
but with some minor changes it would be good to go. I just don't know how
the code would work.

here is what part of my file looks like:
ColumnA Coulmn B Column C Column D
FAULT F02 8
PILLAR 3018169.273 492458.0997 -9771.365343
3017502.798 493106.6833 -8696.365343
3016836.323 493755.2668 -7621.365343
3016169.848 494403.8503 -6546.365343
3015503.373 495052.4339 -5471.365343

Here is what I would like it to look like:
ColumnA ColumnB ColumnC ColumnD ColumnE
PILLAR 3018169.273 492458.0997 -9771.365343 F02
2 3017502.798 493106.6833 -8696.365343 F02
2 3016836.323 493755.2668 -7621.365343 F02
2 3016169.848 494403.8503 -6546.365343 F02
3 3015503.373 495052.4339 -5471.365343 F02

The changes are that below the word Pillar I need it to fill in with 2, 2,
2, 3. There will always be 4 rows below the word PILLAR. The next edit is
that when ever it see's the word Fault I need it to take that Fault name in
this case "F02" in place that in the new column E. Than it can delete the
line with the word "FAULT" in it.

My file will have several of these changes:
FAULT F02 8

So you can see where it gets complicated from time to time. Thank you for
the help.
