Asking this because if not, I think I need to create one while I work through the "learning phase" of the userRPL. The calculator kind of have one build in, but it is only partial.Perhaps Andreas Möller's solutions would be useful for your (but it's commercial software): I also found Debug4x programming SDK there is some nice knowledge "hidden" in its nice Help Index, while I'm not jumping to C programming of the 50g the information provided is partly usefull of understanding some aspects of the calculator. |

There's no need for such a list. It's quite easy: * If there's a 49 version of the program you look for, then use that one. * If there's only a 48 version and not a 49 version, try the 48, it will likely work fine, otherwise somebody would've already "ported" it to the 49. * Anything done for a 49/48GII/49G+ will run on a 50g, with only a few exceptions: a) Games using grayscale may not look good on 49G+/50G due to hardware difference. b) Programs not using the larger screen of the 49G+/50G may have a blank or garbled area below the soft menu (but work fine otherwise). c) Programs depending on specific timing (mostly games) may work too fast on the 49G+/50G. There are programs to slow down the clock on the ARM models that help with this. As you can see, you'd find mostly games have issues, "serious" programs work fine 99.9% of the times. |

RPL Programming Guide from Goodies Disk 4. is a gem, discrace that HP didn't update it when they did launch 49 and 50 calculators, that is one documentation that should be in HPs own download section. *mad* Every single RPL command in the 48 still works on the 50g, so it is highly compatible. The 50g might have more powerful (newer) tools to do some things more efficiently, and lots of additional (new) commands (mostly CAS related) but you won't be wasting your time if you read the 48 documentation. Also, get the 50g AUR with bookmarks and hyperlinks, it's so much better to use than HP's one for quick reference. You can get it from this thread (somewhere in the middle): http://www.hpmuseum.org/forum/thread-3887.html |

RE: HP50g forums / community is there such alive?
Thank you Claudio, that kind of information just is not "easily" available for new user of HPs RPL line of products. Hopefully google will pict this thread.
I have again another question, is there a way to append arroys [..] inside UserRPL programs automaticly (=without dumping the arroy to stack and remaking it with new values)? Ie. for collecting values in loop structures to be used later. The arroy will not be declared at the beginning to final size. I know how to do it with lists {..} (+ command ), but seem to not find a way (atleast for now) to do it with arroys. {[a b] [c d] ... [n m]} atleast might work with some post processing. Also is there a "null" value that can be used in arroy as other datasets like NOVAL is used in some menu related stuff. |

Hello vtile,
{[a,b] [c,d] [e,f]} {[g,h] [i,j] [k,l]} - you get { [a-g,b-h] [c-i,d-j] [e-k,f-l]} But the lists must have same size. {[a,b] [c,d] [e,f]} {[g,h] [i,j] [k,l]} + you get {[a,b] [c,d] [e,f] [g,h] [i,j] [k,l]} {[a,b] [c,d] [e,f]} {[g,h] [i,j] [k,l]} ADD you get { [a+g,b+h] [c+i,d+j] [e+k,f+l]} {[a,b] [c,d] [e,f]} {[g,h] [i,j] [k,l]} DOT you get { a*g+b*h c*i+d*j } and for 3D vectors it works in the same way for CROSS, too. That's fine, isn't it, and I hope I answered your question,too. greetings peacecalc |

This at in UserRPL. Best solution I have found so far (while not tested it inside the program, it seems to work manually) is the doing a empty list object {} named 'TEST' as global and then : TEST : A B 2 ->Arry : + : 'TEST' STO : TEST : C D 2 ->Arry : + : 'TEST' STO TEST = {[A B] [C D]} Still even that seems need to loading the whole variable TEST to stack adding the new object to it and storing it back to its name.. OK.. I think I solved this, while typing the answer for you post, thx. I have been misreading the STO+ commands description (the AUM with links is 100x faster than static one). STO+ do what I'm after, but not in the way the description might give reason to believe. STO- seems not to work (not figured out yet how it works is more correct) atleast it isn't reversed STO+ with same object types involved. Quote:Using STO+ to add two arrays (where obj is an array and name is the global name of an array) requires less memory than using the stack to add them.Need some more testing with all data types it seems, but atleast this is somewhat decent solution for problem in hand. If object test have a list as TEST = {[A B] [C D]} Then: [8 8] 'TEST' STO+ => TEST = {[8 8] [A B] [C D]} Next thing is to test it with pure Arroys, but it might turn to typical adding machine instead of append command. -Vtile |

For arrays, I think you are looking for the COL+ and ROW+ commands, depending on how you want your array organized, each pair could be a row for example, which you can append with ROW+. But in many cases, it's just more convenient to leave your results in the stack until you have the very last one, then you can make a list or an array (only once) at the end of the program. Remember you have an infinite stack, which you can access with PICK/UNPICK and ROLL/ROLLD, and adding an element is as easy as leaving it there. |
