@cindex @code{zero} directive
@cindex filling memory with zero bytes
This directive emits @var{size} 0-valued bytes. @var{size} must be an absolute
expression. This directive is actually an alias for the @samp{.skip} directive
so in can take an optional second argument of the value to store in the bytes
instead of zero. Using @samp{.zero} in this way would be confusing however.
