+## >>> `%downloadFilesTo()` macro: <<< <a name="downloadfilesto-macro"></a> #######################  
+
+The downloadFilesTo() macro copy files (in binary mode
+using `filename()` function with options `lrecl=1 recfm=n`) 
+from list provided by user to a directory indicated 
+in the macro call.
+
+Macro can be executed in two possible ways:
+1) by providing list of files to download in a `datalines4`(`cards4`) list 
+   directly after macro call:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  %downloadFilesTo(</path/to/target/directory>)
+  datalines4;
+  <link to file1>
+  <link to file2>
+   ...
+  <link to fileN>
+  ;;;;
+  run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+2) by create a dataset with a list of links and use of `DS=` and `DSvar=` parameters.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  %downloadFilesTo(</path/to/target/directory>
+  , DS=<dataset with list>
+  , DSvar=<variable with list>
+  )
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+See examples below for the details.
+
+The `%downloadFilesTo()` macro **does not** execute as a pure macro code.
+
+Temporary dataset `work.______locationInfoData` is generated during processing.
+
+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%downloadFilesTo(
+    target
+  <,DS=>
+  <,DSvar=link>
+  <,inDev=URL>
+  <,outDev=DISK>
+  <,inOptions=>
+  <,outOptions=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `target  `     - *Required*, a path to target directory.
+                    If empty the `WORK` location is used.
+
+*. `DS= `         - *Optional*, name of data set with list 
+                    of files to download. 
+
+*. `DSvar= `      - *Optional*, name of variable in data set 
+                    with list of files to download. 
+
+
+*. `inDev=`       - *Optional*, type of device used by the 
+                    `filename()` function to access incoming files.
+                    Default value is `URL`.
+
+*. `outDev=`      - *Optional*, type of device used by the 
+                    `filename()` function to access outgoing files.
+                    Default value is `DISK`.
+
+*. `inOptions=`   - *Optional*, list of additional options for the 
+                    `filename()` function to access incoming files.
+                    Default value is empty.
+
+*. `outOptions=`  - *Optional*, list of additional options for the 
+                    `filename()` function to access outgoing files.
