Does this happen only recently (since the update of PDCurses for DJGPP)?

Which other characters do you get? Can you find out what codes they give in C (using curses). I'm not sure if PDCurses comes with an according test program, but AFAIK the corresponding tests from ncurses can also be used with PDCurses.

If you can't easily test it, perhaps Maurice can. If you have the codes, it should be easy to translate them in crtc.c (e.g., like it's done with PADSTAR etc. which are the normal codes for these keys).

For me (djgpp/w98se/gpc-20020410) * - + work as expected but / and Enter give extended 255 with the following small test program:

-------------------------------------------------------------

program kybtest; uses crt; var c:char; begin writeln('hit some key (end for $)'); repeat c:=readkey; if c=#0 then begin c:=readkey; writeln('extended ',c,ord(c):5) end else writeln(' ',c,ord(c):5); until c='$'; end.

-------------------------------------------------------------

(with BP the same gives all as expected).

Of course, ksUnknown does not tell me much. I'd need the codes as reported by curses in order to do anything about it.

I am not able to write a C program to check.

I stepped through pascal and crtc.c (with rhide) It seems that the curses function is wgetch() if so the results are (for the numeric keypad)

/ 458 * 463 - 464 + 465 Enter 459

It's an old problem I always had, I think, but it becomes really annoying. My version of PDCurses seems to be 2.4.

The problem appears with Readln I tried to write a little program : ***************************** Program keytest; Uses Crt; Const Escape = 256+27; Var Touche : Word; Caractere : Char; Function Bioskey(Commande:Integer):Integer;C; Begin Repeat Writeln('Press a key + ENTER'); Readln(Caractere); Writeln(Caractere,' : ',Ord(Caractere)); Writeln('Press the same key'); Touche := BiosKey(0); Writeln(Chr(Touche),' : ',Touche, ' (',Touche Shr 8,' * 256 + ',Touche And $00FF,')'); Writeln; Until Touche = Escape; End. ***************************** Here is the output I get :

Press a key + ENTER - - : 202 Press the same key / : 13615 (53 * 256 + 47)

Press a key + ENTER ¤ ¤ : 207 Press the same key * : 14122 (55 * 256 + 42)

Press a key + ENTER ð ð : 208 Press the same key - : 18989 (74 * 256 + 45)

Press a key + ENTER Ð Ð : 209 Press the same key + : 20011 (78 * 256 + 43)

Press a key + ENTER - - : 203 Press the same key : 7181 (28 * 256 + 13) *****************************

Of course, if I suppress "Uses Crt", everything is OK.

Thanks for your help. -- "Couperin"
