HP-42s/Free42/DM42 programs RPN is cool. The world needs more RPN. Let's program RPN. Listing export/import on Free42 and DM42 use unicode characters. For gopher client compatibility I am substituting these with ASCII characters, e.g. ^v<> for arrows and C-style inequalities (e.g. x!=0). Hopefully this will be obvious when reading. Raw files are included for direct import into Free42 and DM42.
