+## >>> `%mcDictionary()` macro: <<< <a name="mcdictionary-macro"></a> #######################
+
+The `%mcDictionary()` macro provided in the package 
+is designed to facilitate the idea of a "macro dictionary" 
+concept, i.e. *a list of macrovariables with common prefix 
+and suffixes generated as a hash digest* which allows 
+to use values other than integers as indexes.
+
+The `%mcDictionary()` macro allows to generate other macros 
+which behaves like a dictionary. See examples below.
+
+The `%mcDictionary()` macro executes like a pure macro code.
+
+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%mcDictionary(
+   H
+  <,METHOD>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `H`      - *Required*, a dictionary macro name and a declaration/definition, 
+              e.g. `mcDictionary(HT)`. It names a macro which is generated by
+              the `%mcDictionary()` macro. Provided name cannot be empty 
+              or an underscore (`_`). No longer than *16* characters.
+
+2. `METHOD` - *Optional*, if empty (or DECLARE or DCL) then the code of 
+              a macro dictionary is compiled.
+              If `DELETE` then the macro dictionary named by `H` and all 
+              macrovariables named like "`&H._`" are deleted.
+
+---
+
+### THE CREATED MACRO `%&H.()`: ####################################################
+
+The created macro imitates behaviour of a dictionary. 
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%&H.(
+  METHOD
+  <,KEY=> 
+  <,DATA=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `METHOD` - *Required*, indicate what behaviour should be executed. 
+              Allowed values are:
+                - `ADD`, adds key and data portion to the macro dictionary,
+                   *multiple data portions* are NOT available for one key.
+                - `FIND`, tests if given key exists in the macro dictionary
+                   and, if yes, returns data value associated with the key.
+                   For multiple data portions see the `data=` parameter.
+                - `CHECK`, returns indicator if the key exists in dictionary.
+                - `DEL`, removes key and data portion from the macro dictionary.
+                - `LIST`, prints out a dictionary to the log. 
+                - `CLEAR` removes all data and keys values.
+
+* `KEY=`    - *Optional*, provides key value for `ADD`, `FIND`, `CHECK`
+              and `DEL` methods. 
+              Leading and trimming spaces are removed from the value.
+              The `MD5(...)` function is used to generate the hash.
+              Default value is `_`.
+
+* `DATA=`   - *Optional*, provides data value for the `ADD` method. 
+              Default value is blank.
+
+
+When macro is executed and when data are added the following types of 
+*global* macrovariables are created:
+- `&H._########_K`,
+- `&H._########_V`,
+- `&H._KEYSNUM`.
+
+The `#` represents value generated by the `MD5(...)` function for the given key.
+
+The first type keeps information about the key.
+
+The second type keeps information about the value of a given key
+
+The third type keeps the number of unique values of the key.
+
+See examples below to see use cases.
