<p>The simplest way to use define is to write
</p>
<p><dl class='group--doc'><dd>#define <identifier> <replacement string><br />
</dd>
</dl>
</p>
<p>which will cause all subsequent occurances of 'identifier' to be
replaced with the replacement string.
</p>
<p>Define also has the capability to use arguments, thus a line like
</p>
<p><dl class='group--doc'><dd>#define <identifier>(arg1, arg2) <replacement string><br />
</dd>
</dl>
</p>
<p>would cause identifer to be a macro. All occurances of
'identifier(something1,something2d)' would be replaced with
the replacement string. And in the replacement string, arg1 and arg2
will be replaced with something1 and something2.
</p>
