Yes, and it is totally trivial to do so. I don't have my sources here at
the moment, but it is roughly like this:
c = readknob(); /* or whatever the cmd is for reading it */
if ( c < 64 )
{
print "a";
}
else if ( c < 128 )
{
print "b";
}
else if ( c < 192 )
{
print "c";
}
else
{
print "d";
}
or set a variable inside each if block and then run through a switch
statement later when you're doing your printing.
Sorry if my C is rusty. I do too many languages nowadays...
