# LABEL	# LABEL & $FF	#< LABEL	# LOW LABEL	#L, LABEL	Returns Low byte (LDA LABEL)
/ LABEL	# LABEL / 256	#> LABEL	# HIGH LABEL	#H, LABEL	Returns High byte (LDA LABEL)
BGE LABEL	BCS LABEL	BCS LABEL	BCS LABEL	BCS LABEL	Branch if > = (After a compare)
BLT LABEL	BCC LABEL	BCC LABEL	BCC LABEL	BCC LABEL	Branch it < (After a compare)
.IN "D:PARTZ"	----	.INCLUDE #D:PARTZ"	INCLUDE D:PARTZ	.FI "DI:PARTZ"	Include a file for Assembly

NOTE: The F-S Macro Assembler uses a .AS ^ "HELLO" where the ^ is a Shift *sign.
