Can I enter programs and edit them in the PC simulator? Is there a simple example/tutorial for doing this?
What is the PC simulator for newRPL meant for - can I use it like a 50G with all the features or just for some limited features, or just running RPL?
You are right that the graphical image is purely informative, but use it as a reference as to what the alphabetic keys do. For example the "R" key will take the square root of the number on the stack. If you press "Caps Lock" then "R" it will do X squared, or if you press "Ctrl" then "R" it will take the X'th root of the number in Y, where X is the number in stack level 1 and Y is the number in stack level 2. Etc.
Once you get used to it, it is pretty easy. As for the double arrow brackets "<< >>" you press the "Ctrl" key then the Plus key "+" on your keyboard. The curly braces {} are accessed by pressing "Caps Lock" and Plus "+". After you figure out how to decipher the graphical image it turns out to be a pretty useful reference. Also note that the "Alpha" mode takes a bit of getting used to. Use the "Tab" key to cycle through the three way Alpha modes. The first press of "Tab" puts you into "UPPER CASE" alpha mode, the second press of "Tab" puts you into "lower case" alpha mode, and the third press of "Tab" turns alpha mode off again. I hope that someday they add mouse support for clicking on the keys directly like most other desktop simulators, but for now it DOES have utility and even though it is a bit clumsy I have grown quite fond of the Emulator myself.

RE: newRPL - build 1001 released! [update:build 1016]
I tried the USB connexion between the simulator my PC and my HP50g.

Very easy to install : nothing to do and to use. But i've a problem : I can easily SEND very small objects from the PC to the HP50g. But i'm unable to send objects more than few bytes. The simulator returns 1 on the stack (send OK), but I get nothing on HP50g.

Is this a known problem ?

For exemple, i'm unable to transfert the NewRPL program http://www.hpmuseum.org/forum/thread-9962.html
from the simulator to the HP50g

Have you tried loading the program into the emulator and using "20 USBRESTORE" on the 50G and "USBARCHIVE" on the emulator?

That's not normal. Most of my testings were transferring lists with 10000 integers (generated with a simple FOR loop). at 4 bytes per integer, it was a roughly 40 kbyte transfer with no issues back and forth (automatic ping-pong).
Now I just updated my build environment to latest Ubuntu updates, latest Qt, also updated VirtualBox to latest version and did notice a couple of problems with USB. I can transfer the first object without a hitch, but then the entire USB stack in Linux crashes (??), and the kernel shuts down the USB subsystem. I'm not sure if this is a regression in VirtualBox, Linux, or a bug that was always there and now became apparent.
I need to investigate further, first test I'd do is to try it on real hardware to discard VirtualBox problems. What's your configuration? Running directly on Windows?

No, I tried the USBSEND command.

"ABCD" USBSEND is OK
but it dont work with a larger object

What I trie is, on the simulator :

'MyProgram' RCL USBSEND

EDIT : To Claudio : Yes , Its windows10

Confirmed, thanks for the report. I'll investigate and fix.

Sorry if it seems obvious, but did you run something like
10 USBRECV
on the receiving side?
Otherwise your program will be immediately executed, likely ending with some error, which perhaps vanished before you looked, making it seem like nothing happened.

After restarting my VM, I cannot reproduce any errors, it seems USB is running well, so I spoke too soon, can't find anything wrong with it.
EDIT: Further testing, I can send your program from that thread in ping-pong style without any problems, that doesn't discard there could be some timing problems on your hardware, but that would be extremely difficult to debug without me having your PC.

No... ;D
I just connect the HP50G, click in the simultor do init the connexion.
If I just do "Hello" USBSEND, I get this on first level of the stack in the HP50g.

I will read the doc in this forum or the wiki try again ;D.

That's good news, then there's no problem with your USB connection.
Basically the receiving side will "autoreceive" which includes executing whatever programs you send automatically (for remote control). You can disable it by setting flag -47. When you do, you'll see "RX" on the status area whenever an object is available, which you can receive "manually" using USBRECV.
Be aware that the selection dialog uses the remote control to retrieve the newRPL build number and verify the device is responding, so you need to clear flag -47 in order for the calculator to be recognized in that dialog box.
Now I find more useful to run USBRECV first on the receiving side (which will NOT execute anything automatically), then send it with confidence (without messing with flags). Another trick is to put the program on a list, then you need to extract it from the list on the receiving side, but won't be executed.
If you really don't want to touch your receiving side, then you can send a program to do a remote-controlled-manual-receive (if that makes any sense):
Code:
«   «     10 USBRECV DROP    »   USBSEND DROP    DO USBSEND UNTIL END »

You can call this program SENDOBJ, will send an object without executing it.

Idea:

Show on history view only the level + 1, that is, if not objects in the stack, then display 1:

if there are three objects, display 1: to 4:

I do not see the need to fill the whole screen with numbers

I made the change. I don't necessarily like the look but it is faster not to draw the numbers so I don't object.
I also implemented your suggestion to show the pixel grid. It's disabled by default but can be activated from the menu. I personally prefer not to show the grid.

Those who build their own simulator can test it immediately, others will have to wait until the next release.

Claudio,

Just curious where library objects are in the road map? I've got enough programs now that they would be nice to have.

I'd say solvers are needed first, then forms (GUI, plotting, etc.), then libraries. Libraries in RPL is a challenging subject so it's more interesting to me than plotting, for example. So I'm open to change the order here to libraries, then solvers, then forms. Anyone disagree?

I have to admit that all those things are needed. I'd say stick with your plan.

Claudio if you find libraries more engaging and it could result in fun mode for you, go for it. You are using your free time, you can use it as you whish.

Also libraries allows the community to expand while you do the rest.

Wikis are great, Contribute :)

Alive and kicking. I'm a few days away from releasing the user libraries module, just giving the final touches to the LIBS menu.

Great!

How well does newRPL work on HP 39gs? As well as 50g (besides ROM size)?

The 50g is so expensive these days, and you can get many 39gs for a decent price.

There's no difference in the software, newRPL will behave identical on the 39gs/40 and 50 series. The differences come from the hardware:
a) As you know, ROM and RAM amounts will vary.
b) SD card is obviously not available on the 39/40 unless you add it yourself (search for a post on that, not sure anybody but the original poster ever tried to do it, but it worked for him!)
c) The keyboard layout in newRPL is for obvious reasons following closely the original layout of the 50g, therefore on a 39/40 the labels on the keyboard have nothing to do with what the key actually does. This could change in the future, but I don't have a 39/40 therefore it's not easy for me to decide where you'd want each key to move.

Save for those items, the newRPL experience is nearly identical on all targets.
