+
+The `%expandDataSetsList()` macro is dedicated to "lazy typers".
+
+It allows to expand data set names provides in form of a SAS list for a given library.
+
+See examples below for the details.
+
+The `%expandDataSetsList()` macro works as pure macro code.
+
+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%expandDataSetsList(
+    lib
+   ,datasets
+  <,quote=>
+  <,views=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `lib`              - *Required*, is a name of a library
+                         where data sets are looked-up.  
+
+2. `datasets`         - *Required*, is a list of data sets or views 
+                         to be expanded. Can be named list (e.g. `x_:`),
+                         can be enumerated list (e.g. `y_1-y_5`), or both.
+                         Also the `_ALL_` value is accepted. 
+
+*. `quote`            - *Optional*, binary indicator (default `0` means "no").
+                         Tells if data set names should be quoted. 
+
+*. `views`            - *Optional*, binary indicator (default `1` means "yes").
+                         Tells if views names should be listed too.

+
+The `%unifyVarsCaseSize()` macro converts *all* variables names into low-case or
+upcase letters for given library and list of datasets. Only necessary conversion is
+done, i.e., variable `abc` will not be converted to low-case letters. 
+
+See examples below for the details.
+
+The `%unifyVarsCaseSize()` macro works as pure macro code.
+
+[NOTE:] The macro internally uses the `%expandDataSetsList()` macro.
+
+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%unifyVarsCaseSize(
+    lib
+   ,ds
+  <,case=>
+  <,debug=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `lib`              - *Required*, is a name of a library
+                         where data sets are looked-up.  
+
+2. `ds`               - *Required*, is a list of data sets 
+                         to be expanded. Can be named list (e.g. `x_:`),
+                         can be enumerated list (e.g. `y_1-y_5`), or both.
+                         Also the `_ALL_` value is accepted. 
+
+*. `case`             - *Optional*, single letter indicator (default `L` means "low-case").
+                         Tells if variables names should low-cased (`l`,`L`) or upcased ("u", "U"). 
+
+*. `debug`            - *Optional*, binary indicator (default `0` means "no").
+                         Tells if processing notes should be printed.

+### EXAMPLES AND USECASES: ####################################################
+
+**EXAMPLE 0.** Create data sets for tests:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+data aclass1 aclass2 aclass3 bclass4 bclass5 bclass6;
+  set sashelp.class(obs=6);
+  Nn=_N_;
+  if 1=_N_ then output aclass1;
+  if 2=_N_ then output aclass2;
+  if 3=_N_ then output aclass3;
+  if 4=_N_ then output bclass4;
+  if 5=_N_ then output bclass5;
+  if 6=_N_ then output bclass6;
+run;
+proc print data=aclass1;
+run;
+proc print data=bclass6;
+run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 1.** Convert all variables names to low-case:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%unifyVarsCaseSize(work,aclass:)
+
+proc print data=aclass1;
+proc print data=aclass2;
+proc print data=aclass3;
+run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 2.** Convert all variables names to upcase:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%unifyVarsCaseSize(work,bclass4-bclass6,case=U) 
+
+proc print data=bclass4;
+proc print data=bclass5;
+proc print data=bclass6;
+run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 3.** No conversion done:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+data work.abc;
+  abc=42;
+run;
+
+%unifyVarsCaseSize(work,abc,debug=1)
+
+proc print data=abc;
+run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 4.** Variables in all data sets in `WORK` converted to upcase:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%unifyVarsCaseSize(work,_ALL_,case=L) 
+%unifyVarsCaseSize(work,_ALL_,case=U) 
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
