+
+   B*() is used to specify the base opcode bytes.  Fields to be filled
+        in later, leave zero.  Call this first.
+
+   F() and FE() are used to fill in fields within the base opcode bytes.  You MUST
+        call B*() before any F() or FE().
+
+   [UN]*O*(), PC*() appends operands to the end of the opcode.  You
+        must call P() and B*() before any of these, so that the fixups
+        have the right byte location.
+        O = signed, UO = unsigned, NO = negated, PC = pcrel
+
+   IMM() adds an immediate and fills in the field for it.
+   NIMM() same, but negates the immediate.
+   NBIMM() same, but negates the immediate, for sbb.
+   DSP() adds a displacement, and fills in the field for it.
+
+   Note that order is significant for the O, IMM, and DSP macros, as
+   they append their data to the operand buffer in the order that you
+   call them.
+
+   Use "disp" for displacements whenever possible; this handles the

+selects the 16 most significant bits.
+
+@smallexample
+  movw ax,#%hi16(_sym)
+@end smallexample
+
+@item %hi8()
+
+When loading a 20-bit (or wider) address into registers, this modifier

+
+@cindex line comment character, RL78
+@cindex RL78 line comment character
+The presence of a @samp{;} appearing anywhere on a line indicates the
+start of a comment that extends to the end of that line.
+
+If a @samp{#} appears as the first character of a line then the whole
+line is treated as a comment, but in this case the line can also be a
+logical line number directive (@pxref{Comments}) or a preprocessor
+control command (@pxref{Preprocessing}).
+
+@cindex line separator, RL78
+@cindex statement separator, RL78
+@cindex RL78 line separator
+The @samp{|} character can be used to separate statements on the same
+line.
