http://h30499.www3.hp.com/t5/Calculators/HP-Prime-FW-6030-Units-inconsistency-between-Home-RPN-mode-and/m-p/6534020#M14752
<P>I just got an HP Prime 2 days ago and yesterday I updated the firmware to the latest available (6030). I also updated the HP Prime Virtual calculator to the latest FW (6031) and I noticed an inconsistency in the way units are handled between bot Home RPN mode and CAS mode:</P><P> </P><P>If I try to enter any number of inches (the number doesn't matter, but in the Units menu, you must select Length > in to replicate), I notice the following:</P><P> </P><P>a) in Home RPN mode, if I enter "1in", it is displayed as "1_in", as expected (if I remember correctly from my HP49G+ days)</P><P> </P><P>b) in CAS mode, I get an error message the moment I hit "Enter" with a box containing a white "X" inside a red circle and the message "1_(in)". I tap "OK" to dismiss the message. If I then edit the command line (reading "1_(in)" to "1_(inch)" (by adding the "ch" manually), then I get something like "_(bracket 1 _inch bracket)".</P><P> </P><P>My questions are:</P><P> </P><P>a) It seems that "in" is recognized as a unit in RPN mode, but in CAS mode, the full name "inch" must be spelled out? It does not do the same for "cm" (another unit I tried) which is recognized no problem in both RPN and CAS mode. Why is this inconsistent between modes? Looks like a bug to me.</P><P> </P><P>b) What are all those superfluous characters tagged to units in CAS mode "_(bracket bracket)"? It looks horrible on screen and I have never seen a textbook express units that way. This seems like poor formatting to me (not necessarily a bug, but it surely looks bad)</P><P> </P><P>Thanks and regards.</P><DIV> </DIV><DIV> PS: I had to change the actual brackets in the CAS mode unit formatting to the word "bracket" because the board was choking on "html" and would not let me post.</DIV><DIV> </DIV><DIV> </DIV>Thu, 10 Jul 2014 03:54:26 GMThttp://h30499.www3.hp.com/t5/Calculators/HP-Prime-FW-6030-Units-inconsistency-between-Home-RPN-mode-and/m-p/6534020#M14752deadlocked2014-07-10T03:54:26ZHP50g - subset of a matrix - how to

<P>I copied a cell in a spreadsheet then went to the RPN side to paste to the input line. When I hit enter I get a syntax error.

http://h30499.www3.hp.com/t5/Calculators/HP-Prime-suggestion-for-RPN-Stack-access-in-Programs/m-p/6504860#M14676
<P>First I want to point out that the structure of the programming language is NOT suited for direct stack operations like RPN / RPL.<BR /><BR />I.e. you cannot execute a set of commands on stack arguments.</P><P> </P><P>E.g. in RPN or RPL, to return both the cube and logarithm of the sum of two numbers (assumed to be ready on the stack), you could do:<BR /><BR />RPL:</P><PRE> + DUP 3 ^ SWAP LOG</PRE><P> </P><P>RPN:</P><PRE> + ENTER 3 y^x x<>y LOG</PRE><P> </P><P><BR />these kind of direct stack operations are not suited to be used in an environment like HP-PPL.<BR /><BR />However, it would be convenient to take arguments off the stack and return arguments to the stack.<BR /><BR />For this purpose I propose two commands:<BR /><BR /><FONT face="helvetica">GETSTK(A1,A2,...A<FONT face="times new roman,times"><EM>n</EM></FONT>);</FONT><BR /><FONT face="helvetica">PUTSTK(A1,A2,...A<FONT face="times new roman,times"><EM>n</EM></FONT>);</FONT><BR /><BR />where A1,A2,...A<FONT face="times new roman,times"><EM>n</EM></FONT> are the <FONT face="times new roman,times"><EM>n</EM></FONT> arguments the user wishes to get from or put onto the stack</P><P> </P><P>You can get as many arguments off the stack as you need to use in whatever variation of functions you are using.<BR /><BR />So the above RPN/RPL example becomes:<BR /><BR /></P><PRE>EXPORT PRG1()
BEGIN
LOCAL a,b,c,d;
GETSTK(a,b);
<BR />c=(a+b)^3;
d=LOG(a+b);<BR />
PUTSTK(c,d)
END;</PRE><P> </P><P><BR /><BR />With this one can see that stack manipulation (e.g. DUP, SWAP used above) is not necessary.<BR /><BR />Further notes:<BR />GETSTK basically works like the RPL " <FONT face="courier new,courier">-> a1 a2 ... a<FONT face="times new roman,times"><EM>n</EM></FONT></FONT> " where a<FONT face="times new roman,times"><EM>n</EM></FONT> is level1 argument and a1 is level<FONT face="times new roman,times"><EM>n</EM></FONT> argument.<BR />GETSTK removes the arguments from the stack (similar to RPN/RPL using arguments)<BR />PUTSTK similarly puts A1 on first and A<FONT face="times new roman,times"><EM>n</EM></FONT> on last, i.e. A1 ends up on level<FONT face="times new roman,times"><EM>n</EM></FONT> and A<FONT face="times new roman,times"><EM>n</EM></FONT> on level1.<BR /><BR />Considerations:<BR />GETSTK does similar argument checking as the RPL " <FONT face="courier new,courier">-> a1 a2 ... a<EM><FONT face="times new roman,times">n</FONT></EM></FONT> "<BR />Stack availability use options:<BR />1) GETSTK and PUTSTK check the setting of the calculator and if not in RPN give an error,<BR />OR<BR />2) always use whatever is on the stack (I have noted that the stack seems to hide in the background when not in RPN mode, and upon returning to RPN mode the previous stack with all its history re-appears (in the emulator anyway)).<BR /><BR />However, option 2 may have the user confused about results.</P><P> </P><P> </P><P>In the manual it would also be useful to emphasise that these are the only stack commands available as HP-PPL does not lend itself to direct stack manipulation.<BR /><BR />Just my 2 cents worth.</P>Tue, 10 Jun 2014 14:01:57 GMThttp://h30499.www3.hp.com/t5/Calculators/HP-Prime-suggestion-for-RPN-Stack-access-in-Programs/m-p/6504860#M14676Bart dB2014-06-10T14:01:57ZHP 50g - graph of library function
