Hello, the third argument of REQUEST CMD, what means?

Code: Select all

testReq()
Prgm
  Request "enter x",x,0
EndPrgm

It's to show or hide it in the history once done.

but on ti-68k calculators

On TI 89, the third argument is for "alpha-lock on or off".
If it is 0, then alpha-lock is off... and it allows to enter numbers more easily.
Any other value, or no argument at all gets to alphalock ON.

On Voyage 200... this is totally useless !

Oops yeah, I read "Basic Nspire" in the code box and didn't really look elsewhere ...
Looks like the Nspire Basic is better on this regard, then

sorry for my bad english

The REQUEST CMD (TI-68K CALCS) is practically the same that the REQUEST of the TI-NSPIRE-CX-CAS

example#0

Code: Select all

reqDemo()
Prgm
  ClrIO
  Local statsvar,alphalck
  0→alphalck
  Request "Radious",r,alphalck
  expr(r)→r
  ok→statsvar
  If ok=1 Then
    Disp "Area = π*"&string(r)&"² = "&string(π*r^2.)&" u²"
  EndIf
  Pause:DispHome
EndPrgm

Now if you want to return to the HOME history, use the copytoh89.v2z/89z ASM PRG (renamed to return_h.v2z/89z)

Code: Select all

reqDemo1()
Prgm
  ClrIO
  Local statsvar,radious,area,r
  "radious"→radious
  Request radious,r
  expr(r)→r
  π*r^2.→area
  ok→statsvar
  If statsvar=1 Then
    return_h("radious","area")
  EndIf
EndPrgm

Comparing with the competition (hp-prime) the dialog boxes of Texas Instruments (TI-NSPIRE SERIES) is below, only equals, if the TI-development group re-incorporate to TI-BASIC the following structure (DO YOU AGREE?)

Code: Select all

Dialog

EndDlog

TI figured people didn't really need such dialog boxes, as sequential Request and/or arguments were enough for their purposes.
But it's not really wrong: dialog boxes are just a little graphically fancier, that's all.

Just look at the hundreds of programs that were written in ti-68k language with dialog boxes. //www.ticalc.org (that can not be port). This is a sufficient condition to have incorporated it from the first firmware versions of the ti-nspire series, but it is never late and I expect to see the structure Dialog ... EndDlog returned

With the current form if you want to enter n variables with the current REQUEST you must request them one by one, the code is extended, and is very tedious to enter data by data after pressing [ok]

Look how easy it is to create a dialog box in HPP-PL (HP-PRIME PROGRAMMING LANGUAGE), A solution is LUA, but LUA is not a BASIC-like language, which is equivalent code in LUA?

Equivalent in Lua would be like what FormulaPro has:



The code can be found here https://github.com/adriweb/EEPro-for-Ns ... 0FPGui.lua
But the core of having a few inputs and labels is just a few lines. here it's longer because of all the things it does in addition to just input.
