Hi Alan and Arjen,
Thanks for that piece of information about the f95 implementation
not requiring the array dimensions. With that awareness, I was able
quickly to modify the f77 code to compile correctly.
However, I am now having difficulties when I attempt to
execute. My executable is unable to find the device drivers. Here
is the message I get:
*** PLPLOT ERROR, ABORTING OPERATION ***
plInitDispatchTable: Could not open drivers directory, aborting operation
Requested device wingcc not available
Plotting Options:
Enter device number or keyword:
At the top of my main program, as implied by this output, I have
the line call plsdev('wingcc').
I copied the plplot dll and drivers directories into the
directory where I am trying to execute, hoping that might resolve the
problem. But it did not. Any suggestions as to what I am missing?
Thanks,
John

This is a typical message relating to the available interfaces for
plline. The thing is that with Fortran 95 and beyond you can define
a single interface name to be applied to multiple implementations.
The compiler looks at the actual argument list and decides to use
the implementation that matches that list (by number of arguments
and the type, kind and rank of each). If it can not find any
matching implementation, it will respond with a message like the above.
For the Fortran 95 bindings we have used the features provided by
that standard as much as possible. One is that arrays "know" their
size. So the routine plline queries the arrays xx and yy for their
size and there is no need to pass the size explicitly. That method
is actually rather error-prone.
If you want to pass a section of the array only, you can use:
Call plline( xx(1:10), yy(1:10) )
For instance.
