Are HP 48 library structures documented?

Thanks. I'm not a C guy but if I have to look at C I'll use Kermit's code rather than a derivative. Right now I plan to go based on the Kermit doc rather than looking at code.

You need to also look at Mika Heiskanen's entries.srt file if you want to create commands that are also usable in algebraic expressions.

Thanks. I've downloaded almost everything in site/sight. This one's on the list.

Libraries are quite un-structured -- any apparent structure is due to the few requirements placed on the first few nibbles of a library object and commonly accepted schemes (e.g. how library commands are organized, name hashing, etc.). A library could contain virtually anything. This is why there will never be a library "breaker" that handles all possible ways one can disassemble a library into its components.

Thanks, this is good to know. But specifically, I don't have any interest in breaking apart libraries. I do want to be able to make my own without the complications that the Linux tools seem to require and possibly automate the process ala USERLIB which is not available in Linux.
