             Single Line Assembler ADDRESSING MODES.

Note: This assembler is "Dumb" in it's handling of Address modes
5 and 6; it makes no attempt to decide "what you meant", but only
does "what you say". Also sub-mode 7,2 behaves in a manner similar
to mode 5; sub-mode 7,3 behaves in a manner similiar to mode 6.

Mode 5 appears as a subset of mode 6 where the index register has
been suppressed. That is, if the index register is ommited from the
source code line, mode 5 and mode 6 are indistingushable.  Some
assemblers will always choose the shorter form, mode 5 in this
case. This, however, prevents you from from selecting mode 6 with
index register suppression. This assembler requires you to suppress
a register using the "Z" prefix. You suppress a register
by prepending a "Z" to the register name. The following are
examples:

		($1234,a2,za0)		Suppress the Index register.
		($1234,za3,d7)		Suppress the Base register.
		($1234,zpc,a0)		Suppress the PC register.


		($1234,a2,za0)		Mode 6 (with register suppress).
		($1234,a2)		Mode 5 (with no index register).
