Welcome to my HP 48G AUR Command Reference Guide. Included here are command descriptions and stack diagrams for every command in section 3 of the HP 48G AUR. This page is in no way meant to be a substitute for the actual AUR - that's why I've only included the command descriptions and stack diagrams. I do not intend to add anything else from the AUR to these pages.
You can order the HP 48G Advanced User's Reference Manual directly from HP. The part number is 00048-90136. The address printed on the inside back cover of the AUR is Hewlett-Packard, Calculator Support, 1000 N.E. Circle Road, Corvallis, OR 97330, U.S.A. The telephone number is (503)757-2004 (Mon. - Fri. from 8:00am - 3:00pm Pacific time).
I did type this all in by hand. I used xemacs, shell scripting and a lot of free time to do it. If you find errors, please let me know by emailing me at the address at the bottom of the page. I have attempted to follow exactly the content of the AUR, and in a one case, I have found an error in the delimiters used in the AUR (matrices are always delimited with double square brackets except for one instance in the ROW+ command). I have copied that verbatim. Additionally, in the SIGMA- command, the Level 1 heading is omitted from the stack level table. I have included it. And I can't tell what they're indicating in the square root stack diagram, second result. There is one place in the AUR that had extra text which I left out (the UVAL function). However, it is entirely possible I have introduced a fair number of other errors in my entry of this data. I have carefully checked the information, but I can make no assurances of its accuracy.
As HTML does not have a sufficiently large character set to allow me to perfectly duplicate necessary characters in command names, I have had to take some liberties with command names. In general, greek letters typed in capital letters indicate that the particular letter should be substituted - in particular, SIGMA represents the greek letter sigma, PI represents the greek character pi and GAMMA represents the greek letter gamma. In every case of the name of the reserved variable "SIGMADAT", I have listed it as "EDAT" because when italicized, the E looks sufficiently close to a sigma for my eye. I have used the notation -> to indicate a right-pointing arrow, and UPARROW and DOWNARROW for up- and down-pointing arrows, respectively. For equality tests, <= represents less than or equal to, >= represents greater than or equal to, and =/ represents not equal to. Finally, SQRT indicates the square root symbol.
You can download zip and tgz files of this guide. All files have a .html extension, and many are longer than 8 characters. As errors are pointed out, I will correct them and make available updated zip and tgz files. The latest files were created on June 22, 1998.
