     CSE 109    HW 4    9 PM  Tuesday  25 March 2008

     This homework is an exercise in writing simple Simpletron programs
     and is meant to have you become familiar with the Simpletron language.

     Write two Simpletron programs.  The first should read in a list of non-
     zero integers, the list being of any length, write out each number, and
     write out the cube of the sum of the positive numbers and the square of
     the sum of the negative numbers. The second should read in 5 pairs of
     positive ints and for each pair write 1 if the square of the first
     number in the pair is greater than the second number in the pair and
     writes out a 0 otherwise.  A 0 should serve as a sentinel for the first
     list.  Use sml (stored in /proj/csc109/bin/sml) to make sure your program
     works properly.  Note, with sml you can use the -v option to get more
     verbose output. The first sml program should use the following data:
     18 4 -4 6 12 5 -3 7 6 -4  0.  The second sml program shoud use the
     following data:  3 4 8 3 12 12 17 33 288 12. Of course your programs
     should work for other sets of data.

     To submit your homework, create a subdirectory of cse109.081 called
     hw4 (that is, from your root directory /cse109.081/hw4).  In hw4 store
     two files, the first called hw4.prog1 and containing your first
     Simpletron program and the second called hw4.prog2 and containing your
     second Simpletron program.  The subdirectory hw4 should contain no other
     files.

     NOTE: This homework (and all homeworks) will only be collected once
     (unlike programming assignments, for which there will be multiple
     opportunities to submit your solution).
