Hi John:

I noticed that you were using the f77 binding of PLplot which was
deprecated for release 5.9.10, and dropped for 5.9.11 for the reasons
we mentioned in those release announcements.  Instead, you should be
using the f95 bindings of the latest released version of PLplot which
is 5.10.0.

The support for Fortran 77 in our f95 bindings is actually pretty
good since Fortran 95 generally supports most of Fortran 77. For
example, your Fortran 77 code that worked (more or less) with the f77
binding normally should require very few changes (usually just the
addition of a "use plplot" statement) to work with our latest f95
binding. So please try that possibility with our latest release
(5.10.0), and let us know how it goes.

By the way, we are rewriting much of our f95 binding right now to make
those bindings much simpler for us to maintain, and also to make it a
lot easier to use by our users. For example, that rewritten binding
should provide a version of all PLplot calls with single precision
arguments and also double precision arguments which will be selected
automatically by the f95 binding (via function overloading) depending
on whether all the real arguments of a call to a PLplot Fortran
routine are all single precision or all double precision.  That
updated version is not yet working correctly for us, but when it does
we will commit it to our git master branch to give Fortran users like
you a chance to test it thoroughly on all platforms before we
officially release it. So please keep that future Fortran testing
opportunity in mind (which we will announce here when the time comes).
