Numeric Solver for single formualas
Learning MSOLVR that solves numerically a list of formulas, I learned
to use a little program that manage the screen:
<< NAME STEQ
MINIT
TITLE LVARI MITM
CLEAR
MSOLVR
>>
NAME is the list of equations
TITLE and LVARI are a text string and a list of variables in the
desired order.
In the screen appears the title on the top and the variables down near
the function keys are in the desired order.
I learned that the sequence of keys
NUM.SLV, MSLV
correspond to the RPL command MSOLVR
Now I try to use single formulas numerical sover in the same way.
But I enconter two difficulties:
1) I don't find a RPL command to define the title
2) I don't find the RPL command that correspond to
NUM.SLV
1. Solve equation..
Somebody cam help me?

[gave example of using Multiple Equation (numeric) Solver (MES),
which has MINIT, MITM, MSOLVR setup commands,
and other related programmable commands found in 116 MENU,
yet is actually still a menubased solver, like another mentioned below,
not like the "Solve equation" singleequation form ]

Neither do I; the "Solve equation" form's title is constant.

#B4001h LIBEVAL for the numeric "Solve equation" form on all HP48G/49G/50G.
The only additional programmable command for finding a numeric root
for a variable in a single equation is ROOT (like MROOT of MES).
Alternate, menubased numeric solver, on all HP48/49/50:
'formula' STEQ 30 MENU (even on HP48S[X])
The menubased solver also accepts an equation { list }
just as does MES, but presents only one equation's variables
at a time, and does not automate the equation swapping
or solution procedure.
Go to next equation in list via NXEQ label in menu.
To add menu key definitions to a menu for a single equation:
[see page "188" in HP48G Series User's Guide]
{ 'equation' { keydefs } } STEQ 30 MENU
"HP 48G Series User's Guide" [as a scanned PDF file]
http://www.hpcalc.org/details.php?id=3937
http://www.hpcalc.org/hp48/docs/misc/hp48gug.zip
Almost everything in the above "HP48GUG" (including identical MES,
"Solve equation" form, and 30 MENU original solver)
still applies to HP49G/50G,
which is still like an HP48G[X] plus a far more advanced CAS
and Metakernel tools (e.g. Filer, onboard SysRPL/ML compiler).

Re: Numeric Solver for single formualas
In HP49G+ and HP50G you can use the command MSOLVR2 (very easy to use)
of the library 1210: COMANDOS V102.
This library is in the page:
http://cesarv.wetpaint.com/page/L1210+COMANDOS
In the file there are too 4 directories with examples.
