At select the compilations/Horn section. You will need the Goodies Disc 10 for the hackers tools. One tool, a program L->DIR, takes a library and converts it into the directory which created it.

Goodies Disc 4 is a number of HP tools explaining the SystemRPL and assembly language. You will most likely find that library programs combine these "advanced" code, not the programing language explained in the Users manual.

Tal, based upon the theme of many of your requests, you will find that there is no direct means to accomplish much of what you want to do. You need to learn more; I know I did. You may isolate a program from a library, but you won't know if other segments of the library or even the entire library is necessary to execute the command. I created a library for my own use and it consists of ten interrelated program and data objects. Extract one program and it WON'T WORK! And, I now use SystemRPL more than User code. (I just don't know assembly and judging on the time it took to grow comfortable with SystemRPL...). If you don't have access to manuals of SystemRPL, my programs would make no sense to you. Plus, you can't edit or view them anyway without further non-HP tools (found at

Don't give up but expect a challange.


PS: What library are you attempting to get in to?
