Key remapped in vDOS y/z

[muescha]

I use a german keyboard.

In vDOS on the command line and in my dos programm I can type normal y and z and also the umlauts (öäüß).
The shift modifier works as expected and print: YZÖÄÜ

Things becomes interesting when I try to use it in combination with the modifiers (ctrl/strg or alt). Then the keys are switched. 

I tested it with the helper programm scode: here is it interesting that scode always has switched the y and z and also other keys are the us layout.


As workaround I was able to use KEYCODE to remap the one with the most PITA which was needed because it would be often used in my programm: ctrl+y

KEYCODE = 2C1A=1519
btw. in vDOS the CHCP is 850

Could you post a screenshot of SCODE, mine is:

Only z and y are switched on German vs English keyboard. That's why I have only a foto with this combinations from yesterday:

You got me confused.
I assumed the reported ASCII values of Ctrl+Y or Z were incorrect with your QWERTZ keyboard.

Windows reports no Unicode values since those are missing for Ctrl+... keys.
As a last resort, vDos then indeed mostly fallbacks to the USA keyboard layout definitions.

But your screenshot shows the correct ASCII values. So your test should be for the ASCII value exclusively.
It will then also work with other keyboard layouts like for instance QWERTY or AZERTY, not just QWERTZ.

A (more) KEYCODE= seems no sensible solution, or I’m missing something?

I know that is confusing.

In vDOS everything print in german keys and also in my program the german keys are on the right place. this is fine.

but with SCODE everything is in us english. when I press on keyboard the german z then it shows the english Y SCODE and when I press on german keyboard the german Z it shows Y in SCODE. and the umlauts results in the keys placed on the us english keyboard: []\';


and in the program only the modifier+z/y are switched (I don't tried the other keys with modifiers because I need only the modifier+char without umlauts)


with an multi KEYCODE I would able to switch
ctrl+z = ctrl+y
ctrl+y = ctrl+z

and maybe if i find more problems then I assign them to other keys.

but now my need was only to have ctrl+y to have it on the right place (muscle memory - you know)

I read in other threads that some user need more key assignments for a czech keyboard

SCODE’s key descriptions are based on the scan code. And it will only have them for the US International keyboard.
Those descriptions of course don’t effect how the keys are actually passed on to and handled by DOS programs.

I mentioned Windows doesn’t report an Unicode for Ctrl+char.

LOL, it actually DOES!

But before vDos goes into translating a keypress, it drops the Unicode if Ctrl is down.
That was once added because Wine seemingly misinterpreted Ctrl+char keys.
I commented out the Wine correction and now get:



Seems correct, so you just have to check the ASCII value for Ctrl+Y/Z to let it work with any keyboard layout.
I’ll verify if Wine still needs that correction.

Could you reference the Czech keyboard issue?
That other was specific to DataEase and two years ago: NumLock on, -/+ key of the numeric keypad. So an eventual vDos solution should then also be DataEase specific.

I only referenced to czech keyboard, because there was a requirment for multi - KEYCODE

[Jos]

The Czech keyboard layout is surely to some extend different from US International.
But many are, so I’m merely curious what would be specific to Czech, requiring multi - KEYCODE.

Do you know where to find that Czech keyboard issue?

the request was to remap the full keyboard - I remember one of your solution was to create CP_{number}.txt files for codepage mapping.

[muescha]

there are similar problems where multi KEYCODE maybe was one solution:
- vdos.proboards.com/thread/577/remap-keypad-keys
- vdos.proboards.com/thread/400/keycode-error

[Jos]

Thanks for the links.

The first was already somehow solved, the NumPad +/- keys work as expected in DataPerfect.
The second required a specific codepage. A keyboard remap would be no good.

is KEYCODE a swapping like:

key1 = key2 and key2 = key1

or is it only a one-key replacement?

Key1 = key2 but key2 is still k2

[Jos]

It's no swapping.
So key1 is only substituted by key2.
