Are HP 48 library structures documented?

You may want to learn and use the Hack set of (what else?) hacking tools (I think its called "AS Hack") and also Jazz 6.8. Both found on hpcalc.org. These tools run on the 48 itself and make small edits/recompile/etc. quite easy once you have the major portions coded.

They also include simple to use tools for making and breaking libraries. For example you can create a folder with a number of individual routines, then with a single command, build/transform that into a library. While it's not intended for commercial scale library building, it works fine for hacking together stuff to learn 48 SysRPL and internals.

I strongly suggest you get some 48 RAM Cards. At least a 128KB is needed, but I also suggest a 1MB card (which acts like 8 ports of 128MB cards). They are not cheap, but readily available at TAS.

Enjoy!
