This is just a follow up to my question concerning passing
multi-dimension arrays using call_external. First I want to thank all
those who responded. The answer is rather simple. One just passes
the multi-dimensioned array as a simple array.

Using the example from my original post:

long junk(argc, argv)
int argc;
void *argv[];
{
long *nx,
*ny;

float *arr;

/* Assign passed in arguments */
arr = (float **) argv[0]; /* array */
nx = (long *) argv[1]; /* X dimensions of array */
ny = (long *) argv[2]; /* Y dimensions of array */

z = arr[ix + iy * nx];
}

Thanks again for all the help!
