s.in.ascii

Hi

I am struggling to get s.in.ascii to produce a site file that I can use
for interpolation. I can produce an ascii file containing x, y and a z
column. The z column contains a numerical value that will be used for
interpolation. So far, nothing has worked. I have tried prefixing the z
with a % and without. This puts 0's into the site list. interpolation
gives errors pertaining to invalid formats and no data found. I will be
good and tabulate all the attempts and problems, unless someone can
point me at information that will help me start from scratch again

Thanks

Henk

Henk,

  Is the module broken, or is your input data not in the correct format?
The default field separator is a blank; others must be specified to the
module.

  Just where is the source of the problem, do you think?

I'm not sure. I have followed Markus's advice, and set up a sites file
using the -e option, and get a file that looks correct, "X|Y|%Z". To the
best of my knowledge, the file is in the correct format. I can display
the sites, but cannot interpolate between them
