Matrix :
Nice functions, I'm sorry to nitpick, but for a monochrome screen isn't it B000 instead of B800.
Granted, of course nobody has a mono Hercules adapter anymore.

Wouldn't it be nice to have a big library with all those usefull functions ?
A bit like the old Fidonet Snippets, but with name/register conventions and organised in categories :
- Portable
- Dos
- Win32
....

Nobody should have to reinvent the wheel each time.

yeah, sorry for the long thread, i was thinking about people don't like to download if they only wanna take a look, but i guess i will make all as an attachment, my structure is currently: direct.inc bios.inc dos.inc
my only problem with libraries is i can't include a large library in all my files, maeby i'm lazy to copy my procs to my code? well ... Smile

so you think they whould be better if i make it a zip in an attachment?

, I have one,

Code:


hexBuffer db 0,0,0,0,  0



Start_Ax2Eax:
Ax2Eax:
        ; push cx
        push bx

        mov bx, ax
        and ax, 0xf0f0
        and bx, 0x0f0f
        shr ax, 4
        bswap eax
        mov ax, bx

        ;mov cl, 8
        mov bx, 4
        .again:
                ;cmp al, "9"
                ;jna .nadd
                ;       add al, "A"-"9"
                ;.nadd
                ;add al, "0"
                cmp al,10
                sbb al,69h
                das
                rol eax, 8 ; cl
                dec bx
                jnz .again
        rol eax, 8 ; cl
        xchg ah, al
        bswap eax ; comment this out if you prefer read it in Big-Endian way ¿?¿?¿? .. LOL

        mov [hexBuffer], eax
        pop bx
        ; pop cx
        ret
End_Ax2Eax
%assign Ax2Eax_size End_Ax2Eax-Start_Ax2Eax
%error The size of Ax2Eax is Ax2Eax_size

In that way are 48 bytes of function plus 5 bytes for the buffer, the previous one that I have was with the comments that are now comments.. (uh?), if you delete the preservation of bx and the store to memory the function will be 42 bytes, or the last bswap deleted and you get 39, tought bswap is for convert litle to big and viceversa.. then if you dont mind about.. ¿?.

Hope this help Smile

Why would you? I find these snippets especially useful.
