<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.
