- How familiar are you with machine language programming? HP has an assembler/linker and a set of system-rpl development tools
- that you can get for free that runs on an MS-DOS machine.
-
- Personally, I started ML programming on the HP48 before HP made these tools
- available, so I started out using the Star assembler by Jan Brittenson.
- Personally, I favor the Star assembler over the HP assembler for its use
- of the alternate mnemonic set (courtesy of Alonzo Gariepy) and for its
- powerful macro language. There are things that you can do in Star that
- you just can't do in HP's assembler.
-
- I have developed a fair amount of ML code for the HP48, including a game
- called "Vaders", which is essentially a space invaders clone, and some
- interesting sound development/playing code. In the
- process of doing these things, I have developed a multitasking, multiprocess
- programming environment for the HP48. Now that I have that done, I'm very
- reluctant to change assemblers.
-
- You should note that HP provides _no_ support for their tools. They are
- provided to us strictly out of the goodness of their hearts.
