the error. If I comment out the Plplot calls and compile without
Plplot, the error goes away. It’s acting as if Plplot has occupied all
available I/O units and declared them to be unformatted. How do I fix
this?

Hi Don:

The answer depends on whether this is a regression we have recently
introduced or a long-standing characteristic of our Fortran binding
(or more likely our core C library which is interfaced by that binding
since I believe all the PLplot I/O is done by our core C library).

So to help us formulate that answer, do you get similar problems for
the previous PLplot release (5.10.0) or not?
