COM 1355 Assignment #3.
Assigned:  Thursday, 24 January 2003
Due:       Friday, 27 February 2003

Complete the quirk20 compiler that will be found in

    /course/com1355/Assignments/Assignment3

by implementing a code generator for quirk20 or for one of the
subsets of quirk20 that will be described on the quirk20 web
page.  (Subsets will earn partial credit.  You will get more
credit for writing a reliable code generator for a subset than
for writing an unreliable code generator for a larger subset.)

You may use your own implementation of the type checker and/or
attribute grammar evaluator, or you may use the instructor's.
In some cases, the instructor is providing class files instead
of source files, mainly to prevent students from wasting time
in studying the instructor's poorly commented code.

For this assignment you may modify the instructor's code, but
that is not recommended.  Please report any bugs that you find
in the instructor's code or in the specification of the code
generator.

Please submit your code for this assignment using the script in
/course/com1355/submit-1355.
