                  HP 48 System RPL Development

I am pleased to announce that HP will shortly be making available a set of
tools and documentation that will enable development of HP 48 applications
written in "system RPL," using IBM PC compatible computers as the development
platform.  The tools include an RPL compiler plus the supporting Saturn
assembler and loader.  The documentation includes a description of the RPL
language plus descriptions of the ~2000 supported (i.e.  frozen addresses)
system objects.

This material will be provided on an unsupported basis, meaning that you won't
be able to call up Customer Support for help.  Developers who want more formal
support should register with Hewlett-Packard; the only qualification is to be
able to show that you are engaged in commercial software development for the HP
48.

I am currently reviewing and revising the documentation, after which we will
publish the material.  I am making this preliminary announcement mostly to let
folks who have been struggling with home-brew tool development and trying to
understand the HP 48 internals that help is on the way within a couple of
weeks.  Distribution via the BBS is not practical because of the ~1 Mbyte of
files, but we will make it available on an ftp site (registered developers
will be mailed a disk).

[Top Secret: Don't tell anybody, but the disk that HP Corvallis is mailing to
developers is available from EduCALC as Goodies Disk #4!  Shhhh...  -jkh-]
