Hi, Brendan.  That worked great!

Thanks,

Hi Robert,

You can use the callgeng method as someone else suggested, but you
can also do it within the PRUNE function using static variables.

Inside your PRUNE function do this:

static boolean initialized = FALSE;
...
   if (!initialized)
   {
        --- read in the graphs
        initialized = TRUE;
   }

This will read the graphs in on the first time geng calls the PRUNE
function.  Make sure the data structure used to hold the graphs is
also declared static, so that it won't disappear when the function
returns.

Brendan.
