APL Compiler/Interpreter needed

[matt robinson]

I presently have a need to get a copy of an APL compiler/interpreter for
our systems.  We are running SunOS 4.1.1, with Sun 3/4 setups.  The program
is to be used for a class we currently have here.  Does anyone know of any
one that exists out there?  Please respond by E-mail, and I'll be eternally
in your debt. :)
