We've done a little bit of hand-assembly and hand-disassembly already
this semester. Fortunately, you never have to do that (except in
classes!). Instead, a program called an ``assembler'' translates an
assembly-language program into machine code for you. So, the sequence
for creating a program for the HC11 looks like this:
Execute the command
% source /user/pfeiffer/classes/273/cshrc.cs273
Use your favorite editor to create an assembly-language program.
I recommend emacs, but you can use whatever you want.
