My old turbo pascal book lists <ALT>-<F5> as "27 108", the 27 being an ESCape character. Other shifted, ctrl'd, and alt'd function keys range from "27 84" through "27 113". Also in Norton's 'Programmer's Guide to the PC'.

( ie function keys, pageup, page down, etc) The next call to getch will return the "scan code" of the key hit. You need to do some experimentation to figure out what all the codes are, or find some list. I wrote a program that that prints out the scan code and ascii value of keys pressed, among other things. /*****************************************************************/ /* No copyright, whatsoever */ #include <bios.h> #include <stdio.h> main() { int i=0; while((char)i != 27) { i=bioskey(0); /* get a key if is one waiting, else return 0 */ /* High byte of i is the scan code, the low byte is the ascii*/ if(i!=0) printf("%x %x\n",i,bioskey(2)); /* second call is to get */ /* mod key states */ } } /********************************************************************/ If you don't have turbo-c, then use some interrupt function to call interrupt 16 hex with 0 in _AX for bioskey(0), 16 hex, _AX = 2 for bioskey(2); Return value for both is in AX, I believe. ( and for those of you with extended keyboards, you can add 0x10 to the numbers and get extended codes as well!) Good luck, Robert Blair 6600m00n@ucsbuxa.ucsb.edu

I always used the table in the back of the Basic manual I received with my PC. I have two or three of these little green books kicking around the house now. I believe (from checking my Norton Guides Turbo C++ Database] that the scancode is 00+6C or NULL+108. So check for a NULL, if it is, check for 108. If you get 108, you have an Alt-F5 (that's assuming I have my information correct. It sounds right but without testing... :). Carl Schelin tcs@mailer.jhuapl.edu

I couldn't find a reference to them either so I had to write out
a program to print out their decimal value. This is what I got.
F1 - F10 : NULL+59 - NULL+68
w/ shift: NULL+84 - NULL+93
w/ ctrl : NULL+94 - NULL+103
w/ alt : NULL+104 - NULL+113
From this I get "alt-F5" == NULL+108.
I was unable to get the original post so I'm not sure if this is
exactly what you wanted.

No reason to exhibit the charm Princetonians are famous for :-) The key codes returned by the Alt-keys can be found in the same reference that lists the codes for cursor keys. I use the PS/2 Hardware Technical Reference (a blue ring binder). It goes into some detail how the scan codes differ for various IBM keyboards (each one having been announced as the "standard" keyboard to end all keyboards). Actually, in a pinch you can write a small program that calls the DOS interrupt (one of the very low-numbered services.) It returns a zero byte, then when you call it again the extended code of that key combination. Cay

When I've needed to know such stuff, I couldn't find it either. It turned
out to be a pretty simple C program to read the keyboard and output the
hex values. This also makes it immune from errors in the manual!
I suggest this approach, as you are probably writing a program to read
the keyboard anyway.
