DBL/ and DBLR bugs: 56-bit word size, unsigned math, HEX, 5F7Ed0AE425dF1, ENTER, 3A, ENTER, bE, DBL/.  An HP-16C returns 4EA664Cdb79766 but the emulator returns 4EA664CA644FC4.  Try the same arguments with DBLR.  The HP-16C returns 3d but the emulator returns 277CF2A79.  (These took me several hours of degugging effort to find using my e program, an HP-16C, and Derive software on a PC.)

Nice, thanks.  I think we both got to roughly the same place (LastX = 190).  What does the Derive software do?

This is a good idea, and one I have toyed with; however it may be beyond what can be accomplished for a version 1 program.  The program did not even get released to Beta until the version 1 features were complete.

This is a very good idea.  I think we could add an option for this type of behavior.  It needs to be an option because there will be a certain set of folks who will desire an accurate simulation, without shortcuts.

Let me try to redeem myself after my DBL/ red herring earlier. †(You are right, what I described is not a defect.)

Confirmed and repaired.

I cannot reproduce your particular example:  

1, ENTER, 2, ENTER, 3, ENTER, 4, CLx (blue shift, BSP), 5

This sequence results in a stack of (T) 1, (Z) 2, (Y) 3, (X) 5 on both calculators. †However, I did find a problem where rolling the stack up or down sometimes did not Enable stack lift. †I fixed the latter one.
 
I'm not sure why this was the Root Cause of the problem in your e program, as I haven't yet got the first program to run to completion?  And that one doesn't have a CLx instruction.

3) I could really use a "run at full speed" option when using my 4-hour program to help debug the emulator...

 
I'm still working on this. †As the program instructions are interpreted, and there is large overhead in certain operations, it will never be incredibly fast. Of course, the goal is to emulate the HP-16C, not a P4, but I think we can offer some speed-up.

Explanations: I couldn't make the "find e in binary" program to work on the emulator, so to continue making progress I made a separate program to find e to only 32 decimal places.  It worked (in hindsight, by not encountering the DBL/ and DBLR bugs) and allowed running the 2nd "convert to base 10" program, that failed, due to the CLx RCL(i) sequence not behaving as expected.  I think I then tried the manual 1 ENTER 2 ENTER 3 ENTER 4 Clx 5 sequence just after finding the Clx RCL(i) bug and it failed.  I was doing RollDown at various points to check the stack.  But I can't replicate it now either.  (Fortunately I did mention the core CLx RCL(i) problem.)  AFTER finding the CLx RCL(i) bug, I did the CLx RollDown RCL(i) workaround and went back to the full "find e in binary" program, to find the DBL/ and DBLR bugs.  (Whew!)
 
Bottom line: I will email separately my .16c file that can be used as a test program via Factory Reset, load program, GSB A.  Since the emulator has more register + program memory than the 16C, both halves of the program and all manual setup can be done in the emulator program.  Currently it would take about 4 hours to run.

A few programming bugs
« Reply #26 on: Jun 30th, 2005, 3:58pm »

1.  The clear program command (F-Rdown) should only delete programmed instructions when you are in program edit mode.  In regular calc mode, this command should still reset the current instruction to 0, but should not delete any instructions.
 
2.  The pause command (g-X<>Y) does not work exactly the same as the original hp16c.  I ran into a similar problem with my academic project, and I had to choose not to execute show-base commands from inside of programs.
 
Here is a short program that highlights the differences:
001 - HEX
002 - 9
003 - 8
004 - 7
005 - f-BIN  (show binary)
006 - f-DEC (show decimal)
007 - g-X<>Y (pause)
 
Original calculator will show 100110000111 b for 1 second,
2439 d for 1 second, 987 h for 1 second, and then finish executing the program and show the final result permanently (987 h).
 
Your emulator will just show 2439 d for 1 second, and then it will finish executing and show the final (wrong) result of 100110000111 b.  The calculator should be in hex mode here, not binary.

You're right. †The Clear Program operation was backward. †I think I now have the Show Number Mode stuff working in program run mode.
 
Many thanks to Chris_L and RickN as well as everybody else for helping out with bug reports. †A new Beta has been released tonight.

Jamie,
 
The new rev 1.3.2.10 is great! I especially like the "Execute at Max Speed" and "Tri-Section button" features.  The "e to 400 places" program, re-written to be one long program with no setup needed, executes and gives correct results in about a minute instead of 5 hours.
 
I noticed on the tri-section buttons that the f-shifts have very little vertical mouse distance allocated to them -- having the mouse in the middle of the yellow text is already outside the allowed mouse space.

That's true, but I can't make it test outside of the button itself, and I didn't want it to be easy to accidently hit f+func or g+func.

Regarding the HP-16C Emulator version 1.3.6.15 (8/27/05),
 
I really like it!
 
Enhancement: Remember the on/off state and location of the stack, reg, and program windows so I can quit the program and restart where I left off.
 
Enhancement: Allow resizing of the stack, reg, and program windows.  (The real desire here is to get all 3 of these and the calculator window on-screen at the same time, not overlapping.  Maybe leave them a fixed size, but with non-overlapping layout a goal.  The register window seems to stay at the widest size ever needed which usually includes lots of white space.)
 
Bug: Clicking on the calculator window will not raise it above the stack, reg, or program windows.  I tried "Keep on top" but figured out this keeps the whole set of windows on top of other applications, not what I wanted.

We already do save stack contents, regs, program, and IP. †I agree that saving the state of the stack would allow restarting so I'll add that.

This is a bunch of extra work, but maybe necessary at this point. †I hadn't noticed because I run at 1280 x 960 minimum, but not everybody does.

That's a Windows limitation for child windows and can't be changed, but maybe resizing child windows will make this moot.

Jamie: I mentioned the on/off state and location of the *windows* involved.  I would like to start the application and have all 4 (or fewer) windows onscreen where I last left them, the same size as I last left them.
 
Another thing about resizable windows -- The current Registers window isn't big enough to show a 64-bit register in binary.

True. It would have to be huge by default to satisfy that, however you CAN resize the columns and use a horizontal scroll bar to get to all of the data.

1) I compared the checksum example on page 90-93 of the owners manual with the emulator and got different results.  I did this:
 
- Factory Preset
- Load your provided chksum.16c program
- Initialize registers 1 through A to a 7 b 1 3 d a 2 d 6.
- GSB D (I get "6" which agrees with the manual.)
- x~y (I get "B" which disagrees with the manual's "1".)
 
I didn't check my real 16C, but assume it agrees with the manual.
 
2) Enhancement: Flag 3 displays leading 0s in the calculator display, but not in the Registers window.  (I wanted to see leading 0s in the Register window and this was the way I assumed would do it.)
 
3) Enhancement: Display numbers in the Stack and Registers windows using a fixed-width font so the digit positions line up.  (With 64-bit wordsize, compare 1111111111111111 to CCCCCCCCCCCCCCCC and see the latter appears several digits longer.)

In Program mode with a program in memory so the current IP is shown in the calculator display, right-click on a different step in the Program window and select Move IP to Cursor.  The calculator display stays on the old IP location instead of indicating the new IP location.  (The IP did actually move, as can be seen with SST, BST.)

Thanks for the reports.  As a general rule, there aren't any more enhancements planned for the initial release.  The emulator is feature complete.  I only plan to fix bugs from now to release, which I hope is very soon if all goes well.

Defect (emulator version 1.3.7.16 2005-09-02): Sometimes adding a program step *overwrites* an existing step instead of being *inserted* after the IP.  Do this -- Factory Settings, BSP (to clear Pr Error), P/R, 1, 2, 3 (so you have a program of 3 steps), open the Program window, left-click on step 2 to highlight it, right-click on step 2 and Move IP to Cursor, BSP (to delete step 2 -- so far so good, step 1 ("1") and 2 ("3") remain, and IP appears to be on step 1), 8.  The new step ("8") correctly becomes step 2, but step 3 ("3") is gone.

Jamie: Current comments on www.hp16c.net for the 2005-09-24 version say "Many bug fixes."  Could you list all changes and defects fixed?  It will help those of us doing testing know where to focus our efforts.  If you want to be more private about the defects, please consider posting them only here in the forum instead of on the download website.  - Rick
