Hi everybody,
VPP> I would like to read a character from keyboard as it is
VPP> pressed for my menu system, but I havenät found a way to do
VPP> it, every function that I have found has to wait until enter
VPP> is pressed so send the buffer to my program. If there is a
VPP> way, please tell me.

The C FILE* streams can be tweaked to provide such.
Try something like this:
stdin->flags &= _F_UNBUF
You may have to look into stdio.h to get the actual names.
This is from K&R C.
