@section xc16x Machine Directives

The xc16x version of the assembler supports the following machine
directives:

@table @code
@cindex @code{align} directive, xc16x
@item .align
This directive aligns the section program counter on the next 2-byte
boundary.


@cindex @code{byte} directive, xc16x
@item .byte @var{expr}
This directive assembles a half-word (8-bit) constant.

@cindex @code{word} directive, xc16x
@item .word @var{expr}
This assembles a word (16-bit) constant.

@cindex @code{ascii} directive, xc16x
@item .ascii "@var{ascii}"
This directive used for copying @var{str} into the object file. 
The string is terminated with a null byte.

@cindex @code{set} directive, xc16x
@item .set @var{symbol}, @var{value}
This directive creates a symbol named @var{symbol} which is an alias for
another symbol (possibly not yet defined).  This should not be confused
with the mnemonic @code{set}, which is a legitimate xc16x instruction.


@cindex @code{bss} directive, xc16x
@item .bss @var{symbol}, @var{length}
Reserve @var{length} bytes in the bss section for a local @var{symbol},
aligned to the power of two specified by @var{align}.  @var{length} and
@var{align} must be positive absolute expressions.  This directive
differs from @samp{.lcomm} only in that it permits you to specify
an alignment.
