"All About Applesoft" volume, and though it has useful descriptions of the functions of many Applesoft entry points, it is not a thorough dissection of the ROM. It focuses more on entry points that are likely to be used in a M/L extension to Applesoft than on the "housekeeping" routines. It is a good complement to a ROM disassembly, however. $D6A5 is the start of the LIST routine in the ROM. That would be a good place to start looking. > On Apr 22, 6:41 pm, "Michael J.
