The original HP-PLOT/21 used features of HP FORTRAN/3000.
Around 1980, when I supported it, I rewrote it entirely
in standard FORTRAN, using a highly portable subset of
of the 1966 ANSI standard.  It is designed to be compiled
and run on a wide variety of architectures.

It's a 2-D graphics package consisting of 77 user-callable
routines.  It supports only the 7221 family of plotters.

I don't know whether it's still sold/supported.  If interested,
check with the San Diego Division.  Contact me if you have
trouble finding a lead.
