Good points Don Cragun, my assumption was that the value in the data line was less than then number of lines and any additional lines need to be discarded.
In my solution, any processing could be done in the NR <=R block:
The O.P. said the output "can be directed to a gnuplot ot (sic) output to a file.", but didn't specify any options for gnuplot and didn't specify filenames nor whether the headers should be included in the files or stripped from the files. There is no gnuplot man page in the Man Pages section of this forum, but some references I found said that it is very picky about having its input in tab separated fields (and the data lines given in the sample input have no tabs). Should all data be sent to one instantiation of gnuplot or should the data under each header be sent to a different instantiation of gnuplot?
I don't think I can do much more until we get a clarification on the requirements.
I have a large list of filenames from an Excel sheet, which I then translate into a simple text file. I'd like to use this list, which contains various file extensions , to archive these files and then remove them recursively through multiple directories and subdirectories. So far, it looks like...

tkspline(n) Tk Spline - An additional smoothing method for canvas items tkspline(n)
__________________________________________________________________________________________________________________________________________________NAME
spline, - additional smoothing method for canvas items.
SYNOPSIS
package require Tkspline
...
.c create line ... -smooth spline ...
.c create polygon ... -smooth spline ...
_________________________________________________________________INTRODUCTION
The new option value: -smooth spline provides an additional smoothing method to line and polygon canvas items.
Spline smoothing will revert to the builtin smoothing method unless the number of points is 3n+1, where n is the number of spline segments.
(Normally in polygons this means 3n points because the last point of the spline is understood to be the same as the first in order to close
the polygon).
In line and polygon items, the curves generated with the standard -smooth true option have the following properties:
- the curve is always tangential to a straight line between consecutive points.
- the curve is only guaranteed to intersect the first and last points of lines.
- the curve is not guaranteed to intersect any points of polygons.
With -smooth spline (and the right number of coordinates) the curves generated have the following different properties:
- the curve is guaranteed to intersect the first point, and every third point after that.
- each segment of the curve shares endpoints with the adjacent segments, but is otherwise independent of them.
- the curve is guaranteed to be tangential to a line between n and n+1 at point n, and also to a line between n+2 and n+3 at point n+3.
- the curve is not guaranteed to be smooth at the junctions between segments unless the shared point and the points either side of it are
on a straight line.
These alternative properties are useful to some path planning algorithms.
CREDITS
The underlying Bezier code is in John Ousterhout's original canvas widget, this extension just provides an alternate interface to it. The
hooks into the canvas are provided by Jan Nijtmans in his "dash" patch.
