While using gnuplot 3.5 I find that 'plot "file" using m:n '
seems to have a limit on n.  I have 35 columns of data and
using 1:35 prints out the wrong graph but using 1:2, 1:4 or
anything up to 1:16 works.  Since I'm not the system admin and
don't have access to the source, reompiling is out of the question.
Is there a way to directly plot 1:35 without using awk or cut to
prepare a new data file for me?

Thanx in advance for all advice.

Most likely, you are encountering the maximum line length.
The default is 1000 characters in the source (I think it's
MAXLINELENGTH in command.c, don't have source handy).
Precompiled executables usually use the default.  It's easy
to change and recompile.  Version 3.6 may have removed
this limit on line lengths completely.
