It will at least be more helpful than the manual, which has a really poor index, and makes it really hard to find the description of a specific function. I wish they made something like this for the 50g too, although I'm sure most of this stuff would apply equally well... -- Posted via a free Usenet account from http://www.teranews.com

HP calculators have long had a persistent ENG display mode for engineering notation (like scientific, but forcing the exponent of ten to be a multiple of three), whereas Casio requires you to press an ENG key every time that you want to see such a display; however, in return for this inconvenience, Casio lets multiple presses of the ENG key keep changing the exponent by three more, so as in effect to display "kilowatts" then "megawatts," etc. This can also be done on old and new HP graphing calcs, in several different ways (with real numbers, with specific unit objects, or with generalized "abstract units") See my two posts in this thread, which have further links and programs: http://groups.google.com/group/comp.sys.hp48/browse_frm/thread/74d05086653d7514 To copy programs from postings stored at Google, please click "show options" then "show original" (to get the original, unaltered plaintext) Best wishes from http://www.mum.edu and http://www.maharishischooliowa.org

"most" can be made a bit stronger: The 49G+ and 50G are program-wise *identical* (and even use the same ROM update), save only for additional flag -78 (set for using new serial port as "wire" port), and that some commands like VERSION or SERIAL return "50" for model number instead of "49" The 50G added the serial port, can be powered from the USB cable, has the most improved keyboard and different colors and texture, and otherwise is the same as any 49G+ [r->] [OFF]
