lurking is a good word! lest the students find me! Yes I did write a
version of s.surf.krig its a wonderful fortranest version of a c
program - but at least it is (should be) easy to read. there are no
variogram routines (unless Darell put my fortran semivariogram
routines up as well) - but Yvan Pannettier (spel) has written
VarioWin, which is a wonderful variogram modelling package for
Windows - search for variowin on the web...I missed the earlier discussion so if there were some specific
questions, please repeat or mail me direct...Cheers,
Chris Skelly
sorry about the confusion, all I really wanted was a sample set of
data and the appropriate parameters, so that I could try it out on
s.surf.krig to check it is working properly (after I've hacked it
around to get it to compile on our cranky system 
big thanks to everyone who contributes programs for others to use,
it must be doing you karma a power of good and thanks to all
who have answered my mail.
BTW does any one have any handy hints for removing harden guck from
a flat bed scanner. I thought I'd ask before I nip downstairs and
borrow some acid from the concrete laboratory, cheers

PS my original message was:
Hi
I've been trying to use Darrell's s.surf.krig, could someone email me
^^^^^ sorry Chris
a data set and the input parameters (nugget range etc) so I can see
if I've got it working properly. I've tried using my own data but
I can't get it to work satisfactorially, I suspect I'm not using
correct parameters but I'd like to rule out a bug I may have
introduced while compiling it. BTW has anyone done a cokriger
for GRASS
