+@cindex syntax, RL78
+
+The RL78 has three modifiers that adjust the relocations used by the
+linker:
+
+@table @code
+
+@item %lo16()
+
+When loading a 20-bit (or wider) address into registers, this modifier
+selects the 16 least significant bits.
+
+@smallexample
+  movw ax,#%lo16(_sym)
+@end smallexample
+
+@item %hi16()
+
+When loading a 20-bit (or wider) address into registers, this modifier
+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
+selects the 8 bits that would go into CS or ES (i.e. bits 23..16).
+
+@smallexample
+  mov es, #%hi8(_sym)

+@cindex RL78 assembler directives
+
+In addition to the common directives, the RL78 adds these:
+
+@table @code
+
+@item .double
+Output a constant in ``double'' format, which is a 32-bit floating
+point value on RL78.
+
+@item .bss
+Select the BSS section.
+
+@item .3byte
+Output a constant value in a three byte format.
+
+@item .int
+@itemx .word
+Output a constant value in a four byte format.

+
+@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.
