Thanks, we'll try relinking. As for ncl, are there any examples
available that use NclApiScalar, etc? The two advantages we see
for hlu are the nice example set and the fact that we can call LLU
routines without wrapping them. We're particularly interested
in examples like xyplot/xy12c.c and xy13c.c, which we had planned
to redo, using Tk widgets instead of the Xt and Xm window calls.
