<a name="1205121"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">The <font size=2 face=Courier><strong>blkw</strong></font> directive inserts a block of words in the instruction stream. The number of words to be generated is given by the first expression, the <font size=2 face=Courier><strong><em>size</em></strong></font>. The value of the words is given by the operands which follow the <font size=2 face=Courier><strong><em>size</em></strong></font>. Each of the operands is itself an expression.</font>

<a name="1205122"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">If no operands are given, or the <font size=2 face=Courier><strong><em>size</em></strong></font> given is zero or negative, then zero words are generated. If too few operands are given then the remaining words are set to zero. It is an error to give too many operands to the <font size=2 face=Courier><strong>blkw</strong></font> directive.</font>
