I'm relatively new to sas, but here's what I'm trying to do:

Among my variables, is a dichotomous variable (called 'status') of 1's and
0's
which define whether a tree is alive or dead. The orchard where the trees
reside is a perfect grid and the tree's position can extracted from the row
and
column variables.

i.e.    id        row    col    status    etc
        B7        7        B        1

I want to convert the 'status' variable into a two-dimensional array of 1's
and
0's, and then create a new variable containing the number of dead trees
around
each tree. I 'm just having trouble with the array part and can figure out
the
searching part of the algorythm. Thank you in advance for any help anyone
can provide.
