- You made your own 'Crt'? I'd like some help!
- The only thing I haven't been able to do so far is the stupid KeyPressed...
- I have successfully made a really good ReadKey (return a String [2], so I can
- even read arrows, Functions keys (even F11 and F12))
-
- Here's my ReadKey (I case anybody would like to have it),
- but I you could help me with the KeyPressed...
- (Byt the way, does your 'direct video' is made like this?
- Type
- VideoChar = Record
- Ascii : Char;
- Color : Byte;
- end;
- Var
- VideoRam : Array [1..25,1..80] of VideoChar Absolute $B800:0000; )
-
- Here's my 'ReadKey':
-
- Function Inkey : String;
- Var
- K : Word;
- T : String [2];
- Begin
- Asm
- mov ah, 10h
- int 16h
- mov K, ax
- end;
- T := '';
- If ((K and 255) = 0) or ((K and 255) = 224) then
- T := ' '+ Chr (Trunc ((K and 65280) / 256))
- else
- T := Chr (K and 255);
- Inkey := T;
- End;
-
- So what about a 'KeyPressed' ?
-
- Thanks 'n bye
