Detailed Description

Data structures to manage LISP-like lists.

Author

Olivier Hureau, Hugo Feydel , Julien ALaimo Simple program to test whether running a user program works.

Just do a "syscall" that shuts down the OS.

NOTE: for some reason, user programs with global data structures sometimes haven't worked in the Nachos environment. So be careful out there! One option is to allocate data structures as automatics within a procedure, but if you do this, you have to be careful to allocate a big enough stack to hold the automatics!
