+What is REXX ?
+==============
+
+REXX is a programming language designed by Michael Cowlishaw
+of IBM UK Laboratories.  In his own words:  "REXX is a
+procedural language that allows programs and algorithms to
+be written in a clear and structured way."
+REXX doesn't look that different from any other procedural
+language.  Here's a simple REXX program:
+
+     /* Count some numbers */
+     
+     say "Counting..."
+     do i = 1 to 10
+         say "Number" i
+     end
+
+What makes REXX different from most other languages is that
+it is also designed to be used as a macro language by
+arbitrary application programs.  The idea is that
+application developers don't have to design their own macro
+languages and interpreters.  Instead they use REXX as the
+macro language and support the REXX programming interface.
+If a REXX macro comes across an expression or function call
+that it cannot resolve, it can ask the application to handle
+it instead.  The application only has to support the
+features that are specific to it, freeing the developer from
+handling the mundane (and time-consuming) task of writing a
+language interpreter.  And if all applications use REXX as
+their macro language, the user only has to learn one
+language instead of a dozen.
+
+
+Differences between TRL (The REXX Language) and REXX/imc
+========================================================
+
+The following are all nonstandard features of REXX-imc
+
+ * Rejection of labels ending with dot (in case of confusion between
+   function.(args) and stem.(tail))
+ * Compound variable accesses of the form "stem.'string constant'" and
+   stem.(expression)
+ * Acceptance of any non-zero number for logical truth, rather than just 1
+ * "SAYN expression" to output lines without carriage return
+ * "SELECT expression" to switch on a value
+ * "END SELECT"
+ * "PARSE VALUE" with multiple strings separated by commas
+ * "PROCEDURE HIDE"
+ * The following functions: chdir getcwd getenv putenv system userid
+   plus these I/O functions: open close fdopen popen pclose fileno ftell
+ * error messages 80-210, -1 and -3.
