I was just wondering, has anybody compared the variour versions of the HP
48SX? By this I mean, downloading the memory 00000-7FFFF and generating
a difference report. I guess what I'm really asking is: when doing low
level coding (RPL or ML) what addresses can relied upon. I would guess
anything rthat a Library references is fair game.

This makes bug fixing rather tricky, he observed, but they're HP, so they can do anything. He did imply that perhaps a very few SYSEVAL addresses might move, but only becuase those were deemed not usable from any program other than their callers. Mark Adler madler@piglet.caltech.edu
