Lock CAPS poking memory

[oblo]

I'm reading LastK, and it's for the "redefine keyboard" feature. Here is the code:

Code:

REM subrutina para definir las teclas del juego
sub redefinir()

    print at 16,11; flash 1; "\::"; : pause 0 : pause 0 :    arriba = PEEK 23560
    print at 16,6; "UP _ "; INK 3; chr$(arriba);
    print at 16,25; flash 1; "\::"; : pause 0 : abajo = PEEK 23560
    print at 16,18; "DOWN _ "; INK 3; chr$(abajo);
    print at 17,13; flash 1; "\::"; : pause 0 : izqui = PEEK 23560
    print at 17,6; "LEFT _ "; INK 3; chr$(izqui);
    print at 17,25; flash 1; "\::"; : pause 0 : dere = PEEK 23560
    print at 17,17; "RIGHT _ "; INK 3; chr$(dere);
    
    PRINT AT 18,13; "   ";
    print at 18,13; flash 1; "\::"; : pause 0 : cambio = PEEK 23560
    if cambio = 32 then
        PRINT AT 18,6; "SWAP _ "; INK 3; "SPC";
    else if cambio = 13 then
        PRINT AT 18,6; "SWAP _ "; INK 3; "ENT";
    else
        PRINT AT 18,6; "SWAP _ "; INK 3; chr$(cambio);
    end if
    
    PRINT AT 18,25; "   ";
    print at 18,25; flash 1; "\::"; : pause 0 : subir = PEEK 23560
    if subir = 32 then
        PRINT AT 18,17; "RAISE _ "; INK 3; "SPC";
    else if subir = 13 then
        PRINT AT 18,17; "RAISE _ "; INK 3; "ENT";
    else
        PRINT AT 18,17; "RAISE _ "; INK 3; chr$(subir);
    end if

end sub

I evaluated the 32 substracts option, but it only counts for letter (obviously) so I have to control if the pressed key is a letter or not and right now I'm in the last stage of the game development and... truth is I feel lazy, so I was looking for the shortcut -get CAPS always on :roll:

Cheers


EDIT: tried the values your link says and you were right on BASIC, but it didn't work on ZX Basic. Anyway, there's a thing I don't get. This is what Your Spectrum says:

Specifies cursor. Values zero, one, two or four specify the L/C mode, E mode, G mode or K mode respectively.

How can value 0 be L and C at the same time? Is not any other value/variable in the ZX Spectrum to check that CAPS is ON? And thanks again, 2018 and still learning things about this computer
