We call attention to memory as a numbered collection of storage locations, and use this as motivation for introducing Scheme's vectors (one-dimensional arrays) as a way to access storage from within the high-level language. In the application section, we use vectors to program a simulator for our RISC architecture in Scheme. On Sun, Sep 6, 2009 at 4:45 PM, erik quanstrom wrote: >> True, I feel to be pushed to these.
