+.CONCAT
+
+  Builtin function. The function allows to concatenate a list of string
+  constants separated by commas. The result is a string constant that
+  is the concatentation of all arguments. This function is most useful
+  in macros and when used together with the .STRING builtin function.
+  The function may be used in any case where a string constant is
+  expected.
+
+  Example:
+
+       .include        .concat ("myheader", ".", "inc)
+
+  This is the same as the command
+
+       .include        "myheader.inc"
