Note that if a line starts with a ‘<samp>#</samp>’ 78character then it can also be a logical line number directive 79(see <a href="Comments.html#Comments">Comments</a>) or a preprocessor control command 80(see <a href="Preprocessing.html#Preprocessing">Preprocessing</a>). 81</p> 82<a name="index-line-separator_002c-TIC6X"></a> 83<a name="index-statement-separator_002c-TIC6X"></a> 84<a name="index-TIC6X-line-separator"></a> 85<p>The ‘<samp>@</samp>’ character can be used instead of a newline to separate 86statements. 87</p> 88<p>Instruction, register and functional unit names are case-insensitive. 89<code>as</code> requires fully-specified functional unit names, 90such as ‘<samp>.S1</samp>’, ‘<samp>.L1X</samp>’ or ‘<samp>.D1T2</samp>’, on all instructions 91using a functional unit. 92</p> 93<p>For some instructions, there may be syntactic ambiguity between 94register or functional unit names and the names of labels or other 95symbols.
