HP-48GX & 50G Question Message #1 Posted by Matt Agajanian on 8 Dec 2013, 7:59 p.m. Hi all, although the RPN/RPL stack in limited by available memory, what are the pending operations/parentheses level limits in Equation Entry and Algebraic Expression/Single-Line Entry (' ') modes on both the 48GX and the 50G?

Re: HP-48GX & 50G Question Message #2 Posted by David Hayden on 8 Dec 2013, 9:49 p.m., in response to message #1 by Matt Agajanian Interesting question Matt. I know that algebraic expressions are actually stored in reverse polish notation (aka postfix). So there is no limit in the encoding. The only limit I can think of would be the command line parser and there it is probably limited by available memory. Dave

Re: HP-48GX & 50G Question Message #3 Posted by Matt Agajanian on 8 Dec 2013, 10:17 p.m., in response to message #2 by David Hayden Well Dave, being that my calculator collecting days go as far back as 1972 and, with the release of TI's SR-52/56 models, I still use the pending ops/parentheses levels nomenclature. Even though we are far beyond the AOS days of yore, old habits of applying that technology to modern day calcs is a very worn habit of mine. Thanks for the updated insight.
