I am wondering if it is possible to launch the solve equation app inside of program.

I have a program that does a bit of house-keeping to setup to launch the solve equation app, just wondering how I could tell the program to go ahead and launch it versus have to do the RS 7 ENTER combo after running my program every time.

I am looking to launch this app:

Try calling the built-in menu for the solve equation app from within your program.

To specify a particular page of a menu, enter the number as m.pp, where m is the menu number and pp is the page number (such as 94.02 for page 2 of the TIME menu). If page pp doesn’t exist, page 1 is displayed (94 gives page 1 of
the TIME menu).

SYSEVAL, LIBEVAL and FLASHEVAL can cause calculator memory crash.

To access Solve equation input form use:

# 32002h FLASHEVAL (HP’s 49G/48GII/49G+/50G) or

# B4001h LIBEVAL (HP’s 48G/48GX/48G+ and 49G/48GII/49G+/50G)

yeah I tried that already. All that does is bring the menu up, it doesn't actually launch anything. Also, interestingly, even though I have soft menus enabled normally num.slv comes up in a popup anyway, but when calling it this way it puts it on the soft keys. No idea why that is.

That is incredible. That brings up the old 28S style solver (might also be how the 48 and 49 work, not sure since I don't own them).

For others that might encounter this.
You do the a program as he suggested and execute it.
Then do
5 soft key A
3 soft key B
left shift soft key C
The answer C:2 pops out.

This is as good (if not better) than using the application.

Thanks a ton.

And your English was perfect Smile

How would you go about entering that in a program?
Literally "# 32002h FLASHEVAL" ?

Yes, great. I also prefer this way.

'A=B+C' STEQ 30 MENU
works in HP’s 48SX/S, 48G/GX/G+/GII, 49G/G+ and 50G.

And, to the HP 28S (ROM version 2BB) is
'A=B+C' STEQ #1DE26h SYSEVAL

!!! WARNING !!!
In the HP 28 can not do backup. Sad

THE ADRESS #1DE26h WILL ONLY WORK WITH THE HP28S VERSION 2BB.
To know the version of your calculator, type:
#Ah SYSEVAL <ENTER>

Quote:How would you go about entering that in a program?

Yes. Only:
# 32002h FLASHEVAL
or
#32002h FLASHEVAL

Actually you can do the same safe trick with a different menu number on the 28S (just tried to make sure it still works)

'A=B+C' STEQ 24 MENU

That's a nice collection of HP-28C/28S links. Thanks. The only thing I might add is this one.

I forgot that the menus in the HP 28S can also be accessed through their numbers.
I have read the manual again, and in the Reference Manual (page 142, Edition 2) have the list:

1 ARRY
2 BINARY
3 COMPLEX
4 STRING
5 LIST
6 REAL
7 STACK
8 STORE
9 MEMORY
10 ALGEBRA
11 STAT
12 PRINT
13 PROGRAM CONTROL
14 PROGRAM BRANCH
15 PROGRAM TEST
16 MODE
17 LOGS
18 PLOT
19 CUSTOM
20 Cursor
21 TRIG
22 SOLVE (SOLVR_soft-menu_key)
23 USER
24 Solver (SOLV_key)

Suggest you add a new Forum message titled something like "Useful HP-28 Links" with the same information. This looks like a very useful set to have, but no one will ever find it past next week, buried in this thread.

Hello, Bob Prosperi.
Thanks for your suggestion. I will post the links in a new message.
Best regards.

I agree. It is also true that with a thread named properly one has to search it to find it (if the search function helps), so in doubt I added them to the hp calculators wiki.

Note that I found it only because I am reading through the general forum.

http://www.wiki4hp.com/doku.php?id=resources:start

Moreover with niche sites like hpmuseum.org one can really see how little changes in the search string return totally different results while one would expect that (or other search engines) should be able to handle the small differences:

site:hpmuseum.org useful link 28
I get the http://hpmuseum.org/forum/thread-6444-post-58046.html immediately.

site:hpmuseum.org useful links 28
I never get the wanted thread
