+
+The sortMacroArray() macro
+allow to sort elements of a macro array. 
+
+The **limitation** is that sorted values are limited to 32767 bytes of length.
+
+See examples below for the details.

+~~~~~~~~~~~~~~~~~~~~~~~sas

+    array
+  <,valLength=>
+  <,outSet=> 
+  <,sortseq=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `array`             - *Required*, name of an array generated by the `%array()` macro.
+
+* `valLength = 32767`  - *Optional*, default value is `32767`, 
+                          maximum length of a variable storing macrovariable data.
+                          (the reason of 32767 limitation) 
+
+* `outSet    = _NULL_` - *Optional*, default value is `_NULL_`,
+                          an optional output dataset name. 
+
+* `sortseq  =`         - *Optional*, default value is `LINGUISTIC(NUMERIC_COLLATION = ON)`,
+                          sorting options for use in an internal `Proc SORT`.
