 checking to see

+You can also use variable references here to get the name of a varible
+to test by "indirection" (as we saw in the previous section on
+accessing/setting variables indirectly.  This is not a recommended
+way of doing things because it can be kind of obscure to understand,
+but it is possible to do this:
+
+.nf
+
+    foo = MyVarName
+
+    .ifany [FOO]
+        ...
+    .endif
+.fi
+
+This will test to see if either the variable \'MyVarName\' exists.
+You can also do indirection through an environment variable, but
+this is
+.B really
+not recommended because of the obscurity it introduces into a
+configuration file.  Say, $TERM is set to \'vt100\':
+
+.nf
+    .ifany [$TERM]
+        ...
+    .endif
+.fi
+
+This will test to see if a variable called \'vt100\' exists in the
+symbol table.  Perhaps, not the clearest possible construct!
