Alt-S is CHR$(0) + CHR$(31)
Alt-Q is CHR$(0) + CHR$(16)
You can write a simple program to find out other ones as well...

that will help hime alot thanx

Ascii Alt-Q and ascii Alt-S do not exist.
What Plasma357 put in his answer are the INKEY$ function return codes.And that's not the same than the keyboard sacan codes, that would be different. But nothing is defined in ASCII for Alt-Q and Alt-S.

Right, Antoni, a very important point.
Said another way, QB can identify Alt-Q and Alt-S combination keys via the QB INKEY$ function. But these combination keys are NOT part of the Ascii character set, and INKEY$ has to identify these by using 2 bytes, where for a real Ascii character it only needs to use 1 byte.
As a matter of fact, if I'm not mistaken, none of the combinations with ALT are represented in Ascii code. This means that if you wanted to save the Alt-anykey combination anywhere on a file, for example, you would have to use a two byte scheme to do this, which could get very tedious.

It only gets tedious if you have to remake the function for each program... unless you use modules/libs....
One of my current programs supports two-character combos...... I'm using INP(96) for now... but it is a pain.......

But Plasma's code handles two byte ASCII codes. You see the 'elseif'??? There you go
