+@cindex line comment character, XStormy16
+@cindex XStormy16 line comment character
+@samp{#} is the line comment character.  If a @samp{#} appears as the
+first character of a line, 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 comment character, XStormy16
+@cindex XStormy16 comment character
+A semicolon (@samp{;}) can be used to start a comment that extends
+from wherever the character appears on the line up to the end of the
+line.
+
+@cindex line separator, XStormy16
+@cindex statement separator, XStormy16
+@cindex XStormy16 line separator
+
+The @samp{|} character can be used to separate statements on the same
+line.

+@code{@value{AS}} implements all the standard XStormy16 opcodes.

+
+@table @code
+
+@cindex @code{@@lo} pseudo-op, XStormy16
+@item @@lo()
+Computes the lower 16 bits of the given expression and stores it into
+the immediate operand field of the given instruction.  For example:
+
+    @samp{add r6, @@lo(here - there)}
+
+computes the difference between the address of labels 'here' and
+'there', takes the lower 16 bits of this difference and adds it to
+register 6.
+
+@cindex @code{@@hi} pseudo-op, XStormy16
+@item @@hi()
+Computes the higher 16 bits of the given expression and stores it into
+the immediate operand field of the given instruction.  For example:
+
+    @samp{addc r7, @@hi(here - there)}
+
+computes the difference between the address of labels 'here' and
+'there', takes the upper 16 bits of this difference, shifts it down 16
+bits and then adds it, along with the carry bit, to the value in
+register 7.
