This can work in most cases, but what is needed to make it work depends a lot
on the actual routines used, so there is no easy and portable way. Most
routines of the C library will use a set of zero page locations and expect
some of them to be setup in a special way (the argument stack pointer). Other
routines use the heap or other facilities. So your program has to take care
about the necessary setup.
