/* This is the prototype for the assembly language version. You may
|
|
have always thought that switch statements are implemented as a long
|
|
chain of if / else. Well, sometimes they are. Sometimes they are
|
|
implemented using binary search and still other times they are
|
|
implemented as jump tables.
|
|
|
|
My assembly language version is found in jmptbl.s.
