Keywords: keyboard, ascii codes


Here is a nice little program for finding out what codes each key on the
keyboard is sending to the system - it is especially handy trying to find
out what some function-keys are sending.

The program is developed under UNIX system V on a 3B2/400.

#!/bin/sh
# shar:	Shell Archiver
#	Run the following text with /bin/sh to create:
#	ascii.h
#	code.c
sed 's/^X//' << 'SHAR_EOF' > ascii.h
