This is a program written in HiSoft Basic for calculating RPN-expressions
It really started just a small program to see how difficult it was to handle
rpn expressions (not very). After that it turned into a prime example of
creeping featurism. It has (very limited) macro- and graphic capabilities
and an embryo for help-system.
It is hereby placed into the public domain so you may do whatever you wnat with it
