st: adjacency matrix from neighbors for sppack

Hi all,
I am using Stata 11.2 MP on Mac and Unix. I would like to use the
-sppack- package for social network analysis, but the -spmat-
documentation seems to be incomplete and/or still not usable with
social network data.
(econweb.umd.edu/~prucha/Papers/WP_spmat_2011.pdf)
I have IDs of friends for each individual as an observation
(variables: friend1-friend10). I would like to repeat basically this
exercise, but for -spmat-:
http://www.ats.ucla.edu/stat/stata/code/adj_matrix.htm
It would be great to make use of the banded storage and also trust the
authors to use the matrix sensibly in -spreg- and -spivreg-.
Could anyone help me with making an adjacency (contiguity) matrix from
this data for this use?
Thanks in advance,
Laszlo
