+The bpPIPE() [Base Plus PIPE] macro executes OS command

+Under the hood it uses `_` filename reference to PIPE device.

+## >>> `%dirsAndFiles()` macro: <<< <a name="dirsandfiles-macro"></a> #######################  
+
+The `%dirsAndFiles()` macro allows to extract info about all files 
+and subdirectories of a given `root` directory. 
+
+The extracted info may be just a list of files and subdirectories or, if 
+the `details=` parameter is set to 1, additional operating system information 
+is extracted (information is OSS dependent and gives different results for Linux 
+and for Windows)
+
+The extracted info can be narrowed down to files (`keepFiles=1`) or to 
+directories (`keepDirs=1`) if need be.
+
+The extracted info can be presented in wide or long format (`longFormat=1`).
+
+The extracted info for files can be narrowed down to only files with particular
+extension, for example: `fileExt=sas7bdat`.
+
+The extracted info can be narrowed down maximal path depth 
+by setting up the `maxDepth=` parameter.
+
+See examples below for the details.
+
+### REFERENCES: ###################################################################
+
+The macro is based on Kurt Bremser's "*Talking to Your Host*" article 
+presented at WUSS 2022 conference.
+
+The article is available [here](https://communities.sas.com/t5/SAS-User-Groups-Library/WUSS-Presentation-Talking-to-Your-Host/ta-p/838344)
+and also as an additional content of this package.

+                   Number of parts must be positive integer.
+
+2. `set`         - *Required/Optional*, the name of the dataset to split.
+                   If empty then `&syslast.` is used.
+
+3. `prefix`      - *Required/Optional*, the name-prefix for new datasets.
+                   If missing then set to `part`.

+### EXAMPLES AND USECASES: ####################################################
+
+**EXAMPLE 1.** Split `sashelp.cars` into 7 parts: datasets carsInParts1 to carsInParts7:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  %splitDSIntoParts(7,sashelp.cars, carsInParts)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 2.** By default splits the `_last_` dataset into `part1` to `part3` datasets:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  data lastData;
+    set sashelp.cars;
+  run;
+
+  %splitDSIntoBlocks(3)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 3.** Works with `SPDE` engine too:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  options dlcreatedir;
+  libname test "%sysfunc(pathname(work))/testSPDE";
+  libname test;
+  libname test SPDE "%sysfunc(pathname(work))/testSPDE";
+
+  data test.test;
+    set sashelp.cars;
+  run;
+
+  %splitDSIntoParts(3,test.test,work.spde)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
