Prepare a tab separated file with x y and z and try

s.in.ascii sitefile in=asciifile sep=tab

It this doesn't work, maybe you will need to add a 
progressive integer number to the ascii file, that is, 
x <tab> y <tab> prog <tab> z 
in order to import it properly and to use it with 
interpolation modules.
Hope this helps, it's been some time since I imported
ascii files into site format
Best regards
