Back to RPL ! (HP50G)

It's about 100 times bigger but also 100 times faster, and you can always store the "real" program on the SD card and create a small stub on the calc that loads the program and evaluates it.

I would only add that if size is a problem, hpgcc3 creates small executables that run just like any other object, by using EVAL or embedding it in a program.
Requires a custom ROM, so installation is a bit more involved but other than that it overcomes the size issue and all obstacles you face when working with hpgcc 2.0, including allowing you to create RPL objects and manipulate them from within the C program with ease, including doing STO into variables and directories from C.

I would add, if you get a 2 GB SD card, often it is preformatted with FAT32 and the calculator takes time to start. Formatting the card to FAT16 really makes a difference when starting the calculator (I use a 2 GB card).

Thank you, Ramon. I read this here on the forums years ago in another post when I got my first HP 50g. It is a good point that should be mentioned.
