In the Settings menu of SPIM set Bare Machine OFF, Allow Pseudo Instructions ON, Load Trap File ON, Delayed Branches OFF, Delayed Loads OFF, Mapped IO ON, Quiet OFF.
Run the programs by clicking SimulatorGo and then OK in the pop-up panel.
Add a third subroutine that prints "Wonderful" to the Full, Impractical, Program of the chapter (ass36_6.html). Add an entry to the jump table and a call to the new subroutine to the main routine of the program.

Add several more subroutines that print out various words to the Full, Impractical, Program of the chapter. Put each new entry point into the jump table. Write a loop in the main program so that the entry points in the jump table are invoked in order, one per loop iteration.

Add several additional objects to the Complete Program of ass36_19.html. Modify the main program so that it exercises several of the methods of the objects.

Add two methods to the
Complete Program>
(above).
Add a clear() method
that makes the first byte of an objects
string the null byte (in effect deleting the string).
Add a capitalize() method
that changes each lower case character
of the object's string to a capital
letter.
Do this by adding 0x20 to each lower case letter.
Modify main to test the new methods.

Design an object that has an integer for its data.
Its methods are
set(),
double(), and
print().
The
set()
method is passed a parameter
in $a0 and sets the object's
data to that value.
The
double() method doubles
an object's integer, and the
print() method prints
out the integer.
Write a main routine
that creates several objects and
tests their methods.
