Pascal and Hex etc

Jul 30th, 2006

Hi

I'm trying to use "IBM PC Keyboard Scan Codes" in Pascal which involve Decimal Pair and/or Hex Pair codes. (similar to ASCII).

Could someone please tell me how to use these in VPascal. Preferably not Turbo Pascal, but any Pascal version would be appreciated!

A 'code' example would be
PageUp button being
(00,73) (decimal pair) or
(0x00,0x49) (hex pair).

(data from http://jimprice.com/jim-asc.htm)

Thanks

Hi,

Do you want to know how to obtain scan codes from keyboard or how to translate them to ASCII ?

Hi Denzal,

You need to read port Hex60. The following would work in Turbo Pascal (sorry I don't know VPascal :-)). Please replace underscores (_) with spaces ( ).

uses crt;

var
__sc: byte;

begin
__clrscr;
__repeat
____gotoxy(35,12);
____sc := port[$60]; {this makes sc the value of the scan code}
____write(sc,'___');
__until sc = 1; {exit on escape character}
end.

Greetings,

YS
