 ===========  ==========

+
+Macros
+------
+
+Reader macros are simply blocks of code evaluated by the tokenizer.
+Any reduced values created by the evaluation are appended to the block
+currently being read.
+
+Macros can be used wherever a constant is needed to improve evaluation
+speed.
+
+Example::
+
+    <34 2 mul :border>
+
+    box-width <border> add
+
+
+Currently, macro! values cannot be created by the user.
+A literal macro syntax may be added in the future.
