Hi,

your problem was so cute, see ...

>while (c=getkey() != 'q') {

the while is taking the getkey() return but is not asigning it to c,
you have to associate it before compare, consider something like,

>while ( ( c=getkey() ) != 'q') {
              ^    adding    ^

then you will be putting the getkey() return into c and then comparing with
'q';
it will work!.

Very interesting question.
