It won't crash your calc! You can still exit with EXIT. BUT, you won't
be able to type anything. When you start this program, it will repeat
the get part of the code till getkey returns anything else than 0. If
it's $37 the program will exit. If it something else the program will
jump to getsmall. Here exactly the same thing will happen, except that
program execution will jump to get again.
