bytes. Both <var>number</var> and <var>fill</var> are absolute expressions. If the

comma and <var>fill</var> are omitted, <var>fill</var> is assumed to be zero. The

<var>size</var> suffix, if present, must be one of:

<p>Note - unlike the <code>.dcb</code> directive the ‘<samp>.d</samp>’, ‘<samp>.s</samp>’ and ‘<samp>.x</samp>’
|
||
|
|
suffixes do not indicate that floating-point values are to be inserted.
|
||
|
|
</p>
|
||
|
|
<p>If the <var>size</var> suffix is omitted then ‘<samp>.w</samp>’ is assumed.
|
||
|
|
</p>
|
||
|
|
<p>The byte ordering is target dependent.
