My instances can print the object code of a CompiledMethod in symbolic format. They print into an instance variable, stream, and uses oldPC to determine how many bytes to print in the listing. The inherited variable, sender, is used in an ugly way to hold the method being printed.

	blockReturnTop Print the Return Top Of Stack bytecode.
	doDup Print the Duplicate Top Of Stack bytecode.
	doPop Print the Remove Top Of Stack bytecode.
	jump: Print the Unconditional Jump bytecode.
	jump:if: Print the Conditional Jump bytecode.
	methodReturnConstant: Print the Return Constant bytecode.
	methodReturnReceiver Print the Return Self bytecode.
	methodReturnTop Print the Return Top Of Stack bytecode.
	popIntoLiteralVariable: Print the Remove Top Of Stack And Store Into Literal Variable bytecode.
	popIntoReceiverVariable: Print the Remove Top Of Stack And Store Into Instance Variable bytecode.
	popIntoTemporaryVariable: Print the Remove Top Of Stack And Store Into Temporary Variable bytecode.
	pushActiveContext Print the Push Active Context On Top Of Its Own Stack bytecode.
	pushConstant: Print the Push Constant, value, on Top Of Stack bytecode.
	pushLiteralVariable: Print the Push Contents Of anAssociation On Top Of Stack bytecode.
	pushReceiver Print the Push Active Context's Receiver on Top Of Stack bytecode.
	pushReceiverVariable: Print the Push Contents Of the Receiver's Instance Variable Whose Index is the argument, offset, On Top Of Stack bytecode.
	pushTemporaryVariable: Print the Push Contents Of Temporary Variable Whose Index Is the argument, offset, On Top Of Stack bytecode.
	send:super:numArgs: Print the Send Message With Selector, selector, bytecode. The argument, supered, indicates whether the receiver of the message is specified with 'super' in the source method. The arguments of the message are found in the top numArguments locations on the stack and the receiver just below them.
	storeIntoLiteralVariable: Print the Store Top Of Stack Into Literal Variable Of Method bytecode.
	storeIntoReceiverVariable: Print the Store Top Of Stack Into Instance Variable Of Method bytecode.
	storeIntoTemporaryVariable: Print the Store Top Of Stack Into Temporary Variable Of Method bytecode.

	printClass: Create a file whose name is the argument followed by '.bytes'. Store on the file the symbolic form of the compiled methods of the class.
